Sounds Coming from the Vehicle and Their Meanings

 

                                           Sounds coming from a vehicle can indicate certain malfunctions. If sounds from the car are ignored, problems that could be solved quickly can escalate. These sounds can be caused by various reasons. They can range from noises from the exhaust and front suspension to engine or braking system malfunctions. Based on these sounds, it's appropriate to discuss common issues seen in most cars.

                                                        Noises coming from the engine   

                          • Clicking Sound: This is a sound coming from the top of the engine block. It originates from the valves and pistons. If the oil level is low, a clicking sound will come from the engine. Insufficient oil level prevents the valves from being adequately lubricated. Checking the engine oil level and taking precautions beforehand will prevent the problem.

                           • Humming Sound: The humming sound coming from the engine is primarily caused by the lower section. It's a humming sound that increases with wear on the belt. The V-belt can wear down and loosen over time. When it loosens, the humming sound gradually increases. Malfunctions in the alternator, water pump, or air conditioning components can also cause a humming sound.

                                                        Sounds Coming from the Brakes     

                             • Squeaking Sound: This is the most common sound heard when braking. The main cause of the sound is the brake pads. Wear on the brake pads prevents them from making full contact with the disc when the brakes are applied. If contact with the disc is lost, squeaking sounds will occur.

                            • Grinding or Friction Sound: If you hear a sound like metal rubbing against something when you press the brake, this is a serious problem. It indicates that the brake pads are completely worn out. If not resolved quickly, there will be a sudden drop in braking performance.

                                                  Noises Coming from the Steering System

                           • Clicking or Knocking Sound: Clicking noises coming from the steering wheel are related to the steering box or tie rods. If a clicking sound is heard when the steering wheel is turned, it means that wear has begun in the box section. This fault should be suspected if the steering response is slow.

                         • Humming or Buzzing Sound: If you hear a buzzing or excessive humming sound from the wheel while turning the steering wheel, it indicates wear on the connection between the steering wheel and the wheel. Addressing the problem before it worsens can prevent major malfunctions.

                                                    Noises coming from the transmission 

                Noises originating from the transmission are usually due to a decrease in transmission oil. A decrease in oil level or the use of poor quality oil can increase the noise coming from the transmission. The noise is most noticeable during gear changes. Thorough inspection of transmission components and resolution of wear problems will improve the situation.

                                                         Sounds coming from the exhaust

                  A rattling sound from the exhaust indicates a problem caused by a puncture or wear on the exhaust surface. It's normal for the exhaust to develop punctures over time due to excessive heat. If the sound is very loud when accelerating, it indicates gas leaks. A decaying exhaust system causes these leaks, and the sound intensifies with each acceleration.

                                                            Suspension Noises

                    Squeaking noises coming from the suspension indicate that the shock absorber part is broken or severely worn. If the squeaking noise increases on bumpy roads, checking the shock absorber bushings will solve the problem.

Self-Charging Electric Car Models

 

                            Electric vehicle models have approached modern technology with the initiative of major brands. Vehicles that derive their motor power from electricity have become remarkable with their long-range capability. Recently, the most talked-about are self-charging electric vehicles. By generating their own electrical current, the problem of connecting to an external power source is eliminated. Self-charging vehicles are hybrid models. Hybrid models are systems based on the simultaneous operation of the motor and electricity. Hybrid technology does not rely on external power. It renews energy when braking or when the vehicle is stopped. It extends the battery life in a short time. Simultaneously, gasoline use is activated, converting the energy it receives from there into charging. Some prominent brands are switching to hybrid systems in their electric vehicle models, completely eliminating the need to stop and recharge on the road.

                                                  Self-Charging Electric Vehicles  

                         1. Toyota Corolla Hybrid: This model, developed by Toyota using entirely hybrid technology, features a self-charging system. It generates energy independently by recharging itself during frequent stop-and-go city driving, eliminating external dependence. With a full charge, it has a range of 1000-1200 km.

                        2. Honda CR-V e:HEV: This Honda model, capable of fully self-charging, draws its power from hybrid operation for short distances. It recharges itself when braking in traffic or while waiting at red lights. There's no need to recharge the battery in city driving. With a full tank, it can travel 800-1000 km on a long range.

                      3. Hyundai Tucson Hybrid: This model has two different power outputs. With its self-charging hybrid system, it can travel 80 km in the city. There is no need for external charging. The range will increase slightly when the battery is fully charged. Charging is not necessary in the city; you can continue driving using its self-charging feature.

                     4. Kia Sportage Hybrid: The Sportage model, produced by the KIA brand with hybrid technology, has become independent of external power sources by charging itself. Thanks to its self-renewing technology, it can travel 70-80 km in city driving. Its range increases with a fully charged battery.

                     5. Lexus NX Hybrid: Lexus, experimenting with hybrid technology, achieved a range of 96 km in urban areas. This electric vehicle, notable for its self-recharging technology, allows for comfortable long-distance travel on a full tank.

                     6. Renault Austral E-Tech: Renault's shift towards electric vehicles has greatly contributed to its self-charging system. Its latest model can activate its own charging capacity in city driving, covering 80% of the range. When the hybrid battery mode is activated, it has a range of up to 1200 km.

                     7. Nissan X-Trail e-Power: Nissan has implemented its own brand of electric vehicle technology and developed a self-charging vehicle. It has demonstrated advancement by generating its own electricity in urban areas and achieving long-distance travel. With its dual-motor technology, its range can exceed 1000 km.

                                             How does the self-charging feature work?

             Hybrid technology helps the vehicle convert its own electrical current into power. Electric vehicle models can operate with the power of two motors. Self-charging electric vehicles derive their operating principle from hybrid power. When braking in the city, the motor generator current is activated. The generator converts the electricity it receives from the motor into a charge. The charge is replenished with stop-start driving. It is entirely based on the principle of converting energy from the motor into electricity and charging.

Car Engine RPM Increase Problem and Solution

 

                           A vehicle engine provides performance by operating at a specific RPM level. Sudden increases in RPM, or the engine's inability to regulate itself, can cause malfunctions. When an RPM surge malfunction occurs, the vehicle may exhibit erratic behavior. Problems can progress to spontaneous acceleration, rapid starting, or noisy engine operation. Sudden RPM surges lead to increased fuel consumption. Wear and tear on engine parts can occur, and serious problems may arise over time. The spontaneous increase and decrease in RPM, and its continuation while driving, causes the vehicle to consume more energy than normal. If an RPM surge malfunction occurs, prompt inspection and repair are recommended.

                                                 Reasons for Increased Car Engine RPM

                 1. Dirty or Faulty Throttle Body: The throttle body is responsible for regulating engine speed. If the throttle body becomes dirty, it cannot deliver enough airflow to the engine compartment. This dirt can lead to throttle body malfunction. It is the first part to be checked.

                2. Vacuum Leaks: If vacuum leaks occur along with the part called the intake manifold, the engine will draw in unnecessary air. This airflow, outside of its normal settings, will cause sudden increases and decreases in engine speed. Parts that can cause vacuum leaks should be regularly maintained. 

               3. Sensor Errors: Fluctuations in engine speed can be caused by malfunctions in the engine coolant temperature sensor, temperature sensor, airflow regulator parts, and the accelerator pedal. These parts directly regulate the engine's own settings.

               4. LPG Adjustment Problem: Improper adjustment of the LPG system in vehicles, or failure to check the LPG settings for an extended period, can trigger engine speed problems. If there are gas leaks in the vehicle, the engine speed cannot be adjusted to its full capacity.

            5. Electrical System Problems: If the battery voltage is low or there is wear and tear on the battery, it cannot transmit electrical current properly. A system that does not receive a proper electrical voltage will experience deviations in speed regulation.

         6. Clutch Disc Slippage: If the engine speed increases while moving when the gas pedal is pressed but the vehicle doesn't accelerate, the clutch disc is worn out. The necessary parts should be replaced as soon as possible.

                                           Solution to the Engine Speed ​​Increase Problem

               • Diagnostic tool to identify the problem. 

              • Throttle body cleaning or replacement. 

             • Checking vacuum hoses and related parts. 

            • Maintenance and repair of necessary sensor components.

Car Ignition Failure Symptoms and Repair

 

                                 Ignition failures in vehicles can lead to increasingly serious problems. When the ignition system malfunctions, the vehicle experiences unforeseen problems. The ignition system, which enables the vehicle to start, prevents the vehicle from running if it doesn't receive the necessary electricity. Without ignition, the engine cannot reach full capacity. Ignition engages during the initial start-up. If the ignition doesn't fully reach the spark plugs when the ignition is turned, the engine speed decreases. The car experiences shaking and difficulty starting the engine. It can also lead to sudden stalling. Early detection and repair of ignition system failures will prevent major damage.

                                                  Ignition System Malfunction Symptoms

                        Difficulty Starting the Engine: If the car is difficult to start in the morning or in cold weather, or if it stalls after starting, it indicates an ignition problem. If the engine vibrates excessively and makes a loud noise when the car starts, the problem may be related to the ignition.

                        Engine Misfiring and Shaking: If the vehicle fails to reach a stable RPM after starting and shakes excessively, it means the ignition system is not transmitting electrical power properly. If misfiring occurs while the vehicle is in motion, it indicates a problem with the ignition system and the spark plugs.

                        Power Loss and Acceleration Problem: If the acceleration time drops below normal when the accelerator is pressed, there is a power loss due to the ignition. A decrease in speed again during acceleration is a problem stemming from the same fault.

                         Increased Fuel Consumption: Power loss and strain on the vehicle are factors that increase fuel consumption. Hard operation and inefficient running while the vehicle is in motion lead to rapid fuel depletion.

                       Gasoline Smell from Exhaust: When the ignition doesn't burn sufficiently, the gasoline can't reach the required temperature. This causes a smell or smoke to come from the exhaust.

                                               Ignition System Malfunction Repair     

                   1. Repairing Spark Plugs and Spark Plug Wires: The chrome plating on spark plugs can wear down, preventing them from transmitting power properly to the engine. If the spark plug wires are broken or malfunctioning, they must be replaced as a set. Repairing or restoring them is not possible.

                  2. Ignition Coil: A malfunction in the coil means that insufficient electricity is reaching the cylinder. Ignition coils cannot be repaired. Replacing the coil with a new one after a malfunction will solve the problem.

                 3. Distributor Replacement: Distributor failures are common in older model vehicles. The surface of the part can easily absorb moisture, preventing the clutch from reaching the spark plugs. The part cannot be repaired; replacement with a new one is recommended when it fails.

              4. Ignition Sensor Repair: If the sensor inside the ignition module malfunctions, it can cause the vehicle to stall along with the crankshaft. Identifying and directly replacing the faulty part in the ignition system is the definitive solution to the problem.

How to Choose the Right Oil for Your Vehicle Model

 

                         There are several factors to consider when choosing the right oil for your vehicle model. Selecting the correct oil involves careful calculations, from the car's make to its fuel consumption. Since each brand has its own unique engine operating system, using the wrong engine oil can lead to serious malfunctions. Engine oil selection should be done at professional service centers. For new vehicles, it's wise to entrust the process to experts to ensure optimal performance.

                                                        How should oil be chosen?

                 Fluidity: Oil containers have numbers on the front. Each number represents the appropriate fluidity for the engine of the vehicle make. Using oil that does not provide sufficient performance in terms of fluidity will gradually shorten the engine life.

                 Oil Type: In newer generation vehicles, the oil type is generally synthetic. A synthetic oil type suitable for seasonal conditions is required. Oil types that are not compatible with the vehicle engine and do not transmit fluidity properly will cause damage.

                 Driving Conditions: For continuous city driving, very high-quality oils should be selected. Those who drive long distances should use oils that can withstand high temperatures. If the vehicle is used in dusty environments or harsh weather conditions, frequent oil changes should be performed.

                Fuel Type: Selectivity is key in diesel vehicles. Additive changes are different in diesel engines. Oils that sense the vehicle's operating system are the first choice. In other engine types, quality-enhancing options will be accepted.

                                         Malfunctions Caused by Incorrect Oil Selection

               Using the wrong engine oil can cause malfunctions in the parts that enable the vehicle to operate. The engine will overheat, leading to wear and tear on other parts. Engine components that cannot withstand the heat will quickly fail. Using incompatible oil can cause leaks and, combined with high temperatures, can even lead to a fire in the car. Choosing oil quality that matches the vehicle's engine and the car's brand is paramount to avoid causing further damage.

What to do if the brakes fail while the vehicle is in motion?

 

                         This is the most serious malfunction that can occur in cars. This type of malfunction, which can reach a very dangerous level, brings with it major problems. If the brakes fail while the vehicle is in motion and the car accelerates, it causes great panic for the driver. It's a malfunction caused by brake failure. If the brakes fail, they lose all function. No matter how hard you press the brake pedal, it won't work. Staying calm will prevent a potentially bad scenario.

                                                       What to do if the brakes fail   

                           1. Taking Your Foot Off the Gas: If braking has no effect while the vehicle is traveling at a normal speed, you need to take your foot off the gas. Panicking and holding down the gas pedal will only cause the vehicle to continue increasing its speed.

                          2. Pumping the Brake Pedal: Repeatedly pressing and releasing the brake pedal helps to disperse any air pockets that may have formed. Pressing and holding the brake pedal down quickly won't help. Pumping the brake pedal by pressing and releasing it repeatedly can be beneficial.

                         3. Downshifting Method: In manual cars, it is necessary to reduce speed by downshifting. The vehicle is slowed down by downshifting in a controlled manner. The handbrake is applied and released depending on the decrease in speed. In automatic cars, the gear should be put into "S and L" mode.

                         4. Using the Handbrake Carefully: Pulling the handbrake too quickly will cause the vehicle to swerve. This poses a significant risk of accident. It is advisable to pull and release it slowly and carefully. When downshifting, the handbrake should be used according to the vehicle's deceleration rate.

                      5. Warning the Surroundings by Turning On the Hazard Lights: If the brakes fail and the vehicle is in a crowded area, it's necessary to immediately turn on the car's hazard lights to warn those around you. Hand gestures can also be used to signal a warning to oncoming vehicles or those in front.

                      6. Steering the Vehicle to a Safe Location: Calmly driving the car to the side of the road, into an empty field, or onto an escape ramp will be advantageous. Turning the vehicle towards a steep, inclined area like a ramp will greatly help in reducing speed.

                                                  Things to Avoid Doing in a Panic

                   • Not taking your foot off the gas pedal. 

                  • Pulling and releasing the handbrake suddenly. 

                 • Driving into a crowded area instead of a quiet road. 

                • Trying to stop the vehicle by turning off the ignition.

Reasons for Smoke Coming from the Hood While the Vehicle is in Motion

 

                                  This is a type of malfunction that can occur in vehicles. Smoke rising from the front of the vehicle while it is in motion is a risky situation. It requires calm handling. While smoke from the hood may be normal in some cases, it can sometimes indicate a very serious malfunction. If smoke starts rising from the hood and its intensity increases, it is recommended to stop the vehicle immediately and take precautions. The causes of smoke vary. A malfunction starting in the engine can change as other parts become involved due to overheating. If the cause of the smoke from the hood is correctly identified, repairs can be carried out quickly. Solving the source of the malfunction that triggers the smoke is the primary goal.

                                                Reasons for Smoke Coming Out of the Hood

                     Overheating: The vehicle overheats due to an increase in engine temperature. This can be caused by overheating due to a malfunction in the engine cooling system, resulting in cracks in the pipes. Smoke can also result from a combination of radiator leaks and engine heat.

                     Oil Leak: Oil leaks, such as seepage of engine oil or similar spills, can cause smoke to be produced when combined with heat.

                     Cylinder Head Gasket Failure: Excessive heat is generated after coolant leaks into the combustion chamber. This causes the smoke to rise and increase.

                     Electrical System Malfunction: A cable malfunction in the electrical box produces a small amount of smoke along with high heat. If the electrical system malfunction is significant, the intensity of the smoke gradually increases.

                                                     What to do if smoke starts coming from the hood?

                        1. Stop the Vehicle Safely: After smoke starts coming out, the vehicle needs to be stopped safely. Bring the vehicle to a safe location. Allow the engine to cool down

                         2. Don't Open the Hood Immediately: The hood shouldn't be opened immediately. Because the engine temperature is very high, opening the hood can cause excessive smoke to fill the vehicle. This creates an environment for the release of more heat than necessary.

                         3. Check: Once the engine temperature returns to normal, check the oil level and coolant. This will identify any leaks or pipe cracks.

                      4. Call for Help: If the problem persists after the checks, starting the vehicle will likely lead to a major breakdown. It's wise to call for help if the problem continues.

Symptoms of Clutch Failure in Ford Vehicles

 

                                   Ford malfunctions occur due to various fault types. Some malfunctions recur frequently. One of them is clutch failure. Clutch failures in Ford vehicles can occur suddenly. While the cause of the malfunction increases depending on the vehicle model, in most cases the problem can be fixed with simple methods. If the symptoms of clutch failure are well understood and detected quickly, the repair process becomes easier without prolonging the process. The clutch is directly connected to several parts. If wear or breakage occurs in any of these parts, it affects clutch operation. If the severity of the malfunction is significant, the clutch becomes unusable.

                                                      Clutch Failure Symptoms

                 Clutch Slippage: The engine speed increases but the vehicle doesn't accelerate. Clutch slippage weakens vehicle control and causes difficulty shifting gears.

                  Stiff or Loose Pedal: If there are leaks or spills in the hydraulic system, a clutch malfunction occurs. The pedal becomes loose due to wear.

                  Delayed Gear Shifting: If gears shift slowly even when the clutch is pressed, there is a problem with the clutch system. If the gears don't change at all even when the clutch is pressed, it requires repair quickly.

                       Squeaking or Noisy Sounds: If a squeaking or similar noise is heard when the clutch is pressed while the vehicle is in motion, it should be checked first.

                       Vehicle Vibration: If the vehicle vibrates severely when starting off, it may indicate a major problem with the clutch system. Vibration makes it difficult to start the vehicle and reduces performance while driving.

                                                   Key Sources Causing the Failure

                      Clutch Upper/Lower Mechanism Failure: This is caused by the breakage of plastic parts. If there are leaks in the hydraulic system supplying power to the clutch, problems will manifest themselves in the upper and lower mechanisms.

                       Clutch Disc Life: Heavy city traffic, frequent stop-and-go driving, and prolonged use at high RPMs shorten clutch disc life. Clutch disc failures directly affect the clutch assembly and can quickly worsen the problem.

                        Clutch Switch: This is a crucial part that ensures the clutch assembly functions correctly and properly. If the clutch switch malfunctions, it can cause the vehicle to struggle when starting off and on inclines.

Throttle Body Troubleshooting and Repair

 

                                 Throttle body malfunction is a type of fault that should not be taken lightly and requires repair. A malfunction in the throttle body directly affects the vehicle's performance. While the pulling power weakens, if left untreated, it can lead to serious problems. If it affects many related parts, it can cause significantly higher material damage than normal. Throttle body malfunctions stem from many causes related to the parts. Sometimes they are due to simple reasons, but more often they develop into a type of malfunction involving more advanced parts. Throttle body malfunctions require on-site diagnosis and the correct repair method, and preventative measures should be taken without delay.

                                                        Causes of Malfunction

                         • Excessive Contamination and Clogging

                        • Electrical Problems

                        • Mechanical Wear

                                         What are the symptoms of a malfunction?

                1. Irregular Idling: The engine speed constantly fluctuates when the vehicle is idling. It can rise excessively or drop suddenly, as if it's about to stop.

               2. Lack of Acceleration and Delayed Speed: There is a problem with sensing when the accelerator is pressed. Acceleration problems occur later. Sudden acceleration followed by sudden deceleration issues are observed.

              3. Misfiring or Stalling: If the vehicle misfires or suddenly stalls while in motion, there is a blockage in the throttle body. This prevents the vehicle from running smoothly.

             4. Warning Light: If the instrument panel displays a warning light related to an engine malfunction, it may indicate a throttle body malfunction. Inspection and diagnosis are required.

                                                    Throttle Body Repair

                   Throttle Body Cleaning: The throttle body is removed, and all necessary cleaning and general maintenance are performed. If replacement is necessary, the throttle body part is replaced with a new one.

                 Sensor Replacement: If there is no advanced fault in the throttle body and the fault is caused by the sensor, replacing the sensor will suffice. There is no need to replace the entire throttle body.

                   Complete Replacement: If the throttle body is malfunctioning, shows significant wear, and there are problems with the electronic motor, a complete replacement of the parts will solve the issue. Otherwise, the same fault may recur after a certain period following the repair.

How to turn off the Ford Engine Malfunction Light

 

                                    Ford malfunctions are based on technical problems. Ford models may experience chronic electrical or ECU (engine control unit) issues. While they don't usually lead to major breakdowns, the warning light on the dashboard can be annoying. Why does the Engine Malfunction Light Come On? This can happen in Ford models. A warning on the dashboard indicating an engine malfunction suggests a normal malfunction or a very serious problem. It may flash intermittently, or it may become permanently visible every time the vehicle is started. If an Engine Malfunction Warning appears, Ford vehicles should be serviced. Ignoring the problem can cause the engine malfunction to spread to other parts of the vehicle.

                                        Why does the engine malfunction light come on?

                When the engine malfunction light comes on, it indicates an electrical problem directly related to the engine control unit (ECU). If one of the parts that plays an active role in engine operation malfunctions or breaks down, the engine malfunction light will automatically illuminate. It is not directly related to the engine itself. If the parts that act as a bridge between the engine and the ECU are repaired, the warning light will disappear shortly. However, if the warning light persists despite such checks and repairs, it indicates a problem with the engine itself. Immediate intervention is strongly recommended.

                                   How to turn off the engine malfunction light

              Among Ford malfunctions, the engine malfunction light is a prominent feature, and this type of fault can be resolved by repairing the faulty part. If there is a malfunction in the parts that establish an electrical connection with the ECU (engine control unit), they should be checked and serviced. After the necessary repair work, the engine malfunction light should turn off. If the engine malfunction light continues to stay on after fault diagnosis or repair, it indicates a serious problem with the vehicle's engine. Having the engine compartment checked by a technical service center and starting the appropriate repair work as soon as possible will solve the problem.

Oil Burning Problem in Ford Focus Vehicles

 

                             "Oil burning" is a common problem among Ford malfunctions. If an oil burning issue occurs in Ford Focus models, prompt action is necessary. If left unchecked, oil burning can worsen and affect many components. Oil circulation, which directly contributes to the engine's performance, impacts engine power in various malfunctions. Engine power decreases, and the problem can even lead to the vehicle's system shutting down. Oil burning issues are diagnosed on-site, and early intervention ensures successful results. In Ford Focus vehicles, malfunctions indicating oil burning are evident, and it's necessary to inspect the relevant parts to understand the problem.

                                                     Signs of Fat Burning

                • Blue smoke coming from the exhaust 

               • The vehicle constantly consuming oil 

              • Significant decrease in engine performance 

             • Oily residue on the spark plugs and exhaust 

            • The oil warning light frequently coming on

                                                    Reasons for Fat Burning

                       1. Piston Ring Wear: If the piston rings inside the engine wear out, oil leaks into the combustion chamber. Due to engine heat and piston insufficiency, the oil begins to burn itself inside. Leaks will start over time.

                     2. Valve Seals: Valve seals and gaskets harden and wear over time. As a result of hardening, oil continues to leak out. Hardening and excessive loosening of valve seals cause an oil burning malfunction.

                     3. Turbocharger Failure: If the vehicle has an aftermarket turbocharger, oil leaks can cause oil burning. If the turbocharger leaks oil, it will cause oil burning due to overheating.

                   4. Cylinder Wear: If the internal surface parts of the engine wear down and become deformed, oil burning will occur over time. If the cylinder operation system goes out of control, it will cause excessive oil loss.

                 5. Using the Wrong Oil: The most suitable oil for Ford Focus vehicles must be selected. If low-quality oil or oil with very low levels is used, oil leaks will occur, leading to combustion. Care should be taken to use oil compatible with the vehicle model.

                                                        Repairing Oil Burning Malfunction     

                          • Piston ring replacement

                        • Valve adjustment and replacement if necessary

Reasons for Noises When Turning the Steering Wheel

 

There are multiple reasons for noises coming from the steering wheel. Inspections should start with the steering box and extend to the suspension system. Some noises in the vehicle indicate a steering wheel malfunction. It's not possible to immediately identify the problem based solely on the noise. The root cause of the problem needs to be determined through thorough inspection. Identifying the noises coming from the steering wheel will help in determining the cause. Service centers can easily diagnose steering wheel noise problems by connecting the vehicle to a computer. Listing the identified problem and the parts causing it will greatly assist in the repair process.

                                                     The Sound and Its Causes

                    1. Squeaking/Frictioning Noise: If there is wear in the steering box, it will produce a squeaking sound when the steering wheel is turned. If the tie rod ends dry out or wear occurs at their tips, it will also cause a friction noise.

                  2. Rattling Noises: If the tie rod ends experience a severe malfunction, a rattling sound will occur when the steering wheel is turned. A loosened stabilizer bar is the same cause of the malfunction. The stabilizer bar is the part that holds the steering components in place. Its deterioration or loosening will cause rattling noises. Worn-out suspension bushings that are no longer functioning properly will increase the rattling sound on rough roads.

                3. Humming Noises: If the power steering fluid is low or leaking, it will turn into a loud humming sound. If there is a malfunction or wear in the power steering pump, the humming sound will be heard more intensely when the steering wheel is turned.

              4. Cracking Noises: If you hear a crackling sound when the steering wheel is turned fully to the right or left, there is a problem with the axle head. Replacing the axle head should stop the noise from the steering wheel. Some malfunctions may be less severe. The noise may stop again if repaired or maintained.

               5. Tire or Surface-Related Noises: Tires that are worn or have a damaged surface can cause various noises. Low tire pressure will also cause steering noise. Steering noise should disappear after tire maintenance.

                                         When Should a Malfunction Be Taken Seriously?

              . If the noise is increasing day by day

            . if the vehicle is vibrating 

           . if the steering wheel is pulling the vehicle from side to side 

           . if the steering wheel is stiff

Turbocharger Failure Causes and Repair

 

                                      Turbocharger failures in vehicles can be quite troublesome. The turbocharger is a component directly related to the vehicle's performance. If its relationship with the engine is poor, it restricts the vehicle's normal operating potential. If turbocharger failure progresses and is left untreated, a noticeable decrease in pulling power will occur. As engine power weakens, the extent of the malfunction can progress all the way to the exhaust outlet. Turbocharger maintenance and, if necessary, repair are essential to prevent problems. Immediate intervention when a malfunction occurs in the vehicle's turbocharger is a priority. The turbocharger works in conjunction with many other parts, and a problem in this area can have a ripple effect on other components.

                                                    Turbocharger Failure Causes

                       1. Lubrication Problem: The turbocharger is a mechanism that operates at high speeds. Over time, it will experience wear and tear. If there is a lack of oil, the use of old oil, or leaks, the turbocharger will lose its operational capacity. A decrease in engine speed will occur, triggering a malfunction.

                        2. Air Filter Contamination: If the air filter becomes dirty or clogged, the turbocharger cannot operate at the desired speed. Due to the contamination, no current is sent to the engine. Contamination originating from the turbocharger can also cause fan malfunctions.

                      3. High Temperature: If the engine heats up more than normal, it will cause the turbocharger to wear out due to the heat. Suddenly stopping the vehicle after a long journey can seriously damage the turbocharger due to the high temperature.

                    4. Foreign Object Entry: If foreign objects enter the turbocharger, the turbo impeller may break. Especially if hard objects get into the turbocharger, the impeller can shatter. This will lead to serious malfunctions.

               5. Pressure Problems: If excessively high pressure builds up in the vehicle, it can damage the turbocharger. High or low pressure flow prevents the turbo from functioning properly. Over time, the symptoms of malfunction become noticeably more severe.

                                                             Turbocharger Failure Symptoms

                         • Loss of power 

                       • Black or blue smoke from the exhaust 

                      • Humming noise in the engine 

                     • Oil consumption and leaks 

                    • Engine malfunction warning light coming on

                                                  How to Repair a Turbocharger

                       1. Fault Diagnosis: At the service center, the vehicle is connected to a computer for fault diagnosis. A pressure test is performed to check the level. Oil leaks are checked. The degree of play in the turbocharger is measured.

                       2. Turbo Removal: The turbocharger is carefully removed, and all its parts are checked. It is connected to a diagnostic device for testing. Parts giving warning signals are repaired or replaced.

                    3. Repair and Parts Replacement: Following tests and inspections, bearings, seals, shafts, and propellers (if faulty) are replaced. If the severity of the fault is low, repair work is carried out on the parts.

                  4. Cleaning: The oil channels are meticulously cleaned, and any clogged sections are cleared. After repairing leaks, cleaning continues in the same area. Important hoses leading to the turbo are also cleaned and replaced if necessary.

                 5. Installation and Testing: The turbocharger is correctly installed. It is checked again for any errors. A test drive is conducted to observe pressure changes, RPM, and engine performance. Oil pressure and any new leaks are checked, and the same test drive is repeated several times.

How to Check and Change the Engine Oil of a Vehicle

 

                                  Regular checks of engine oil in a vehicle are essential. Engine oil directly affects the vehicle's operating system. Low oil levels, incorrect oil usage, oil leaks, and filling the oil level below the required level are all harmful. How to Check Engine Oil? It is logical to determine the correct oil level and complete the changes appropriate for the vehicle make. The danger arising from low engine oil can trigger malfunctions that eventually spread to engine parts. If the source of the malfunction is not clearly understood and addressed, unexpected problems will occur in the vehicle due to the oil level.

                                                        How to Check Engine Oil     

                               1. Checking Before Starting the Vehicle: To check the engine oil, the vehicle engine must be cold. The dipstick should be removed before starting the car.

                             2. Opening the Hood to Remove the Oil Dipstick: After opening the hood, pull out the oil dipstick. Wipe the tip with a clean cloth and reinsert it. Wait a moment before putting it back in.

                             3. Checking by Re-removing the Dipstick: After cleaning and putting it back in, remove the dipstick again and check the tip. The tip of the dipstick indicates the oil level. If the oil level is below or halfway down, it indicates the need for refilling.

                           4. Cleaning and Reinserting the Oil Dipstick: Once the necessary checks have been performed on the engine oil dipstick, the tip should be cleaned again before reinserting it. No tampering or excessive pressure should be applied.

                                                         How to Change Engine Oil       

                             • Opening the Engine Oil Cap: Once the hood is open, the oil cap is located on the top or side of the engine. The cap has a symbol indicating "Oil". Wear gloves when opening the cap. Ensure the engine is cold. Never open the oil cap on a hot engine.      

                             • Proper Oil Selection: The most suitable oil for the vehicle make and model is selected. Choosing the right oil is crucial as it directly affects engine power and performance. Using the wrong or very low-quality oil can quickly affect engine performance and lead to serious malfunctions.

                            • Filling with Oil Using a Funnel: After opening the oil cap, a wide-mouthed funnel is placed over the cap area. Oil is carefully poured through the funnel. Avoid splashing or spilling. Visually inspect the engine through the cover and complete the filling process until the oil level is sufficient.

                          • Oil Dipstick Removal and Check: In the final stage, the oil dipstick is checked one last time. Wait 5-10 minutes after filling with oil. Remove the dipstick, clean it, and reinsert it. After waiting and removing it, if the oil level is sufficient, the process is complete.

Vehicle Door Lock System Malfunctions and Repair

 

                             Door lock system malfunctions, a common problem in vehicles, are based on specific causes. There are important parts underlying the lock system. It's difficult to diagnose the problem without knowing its source. All connections that work in conjunction with the lock system are checked. This involves meticulous work, from the battery to the ignition switch battery. In some vehicles, even engine power can affect the system. The lock system weakening to the point of exhaustion can progress to the point of trapping the driver inside the vehicle. Complete door failure can develop into a malfunction affecting other components.

                                              What are the symptoms of a malfunction?    

                     • Doors not locking or unlocking at all. 

                   • Only one door working, the others malfunctioning.

                  • Control being possible from inside the vehicle even though the remote control is not working. 

                • Locks opening and closing by themselves, causing loss of control. 

               • Sound coming from the remote control but the doors not opening.

                                                           Causes of Malfunction

                  1. Central Locking Motor Failure: The motor is the brain of the locking system. If the locking motor malfunctions, the door locking system becomes uncontrollable. The remote control will become inoperative. Generally, the inability of a single door to open or close is the cause of a motor failure.

                2. Fuse or Electrical Problem: A blown fuse can occur in the fuse box, directly affecting the vehicle's locking system. If electrical current is not transmitted to the locking system, contact cannot be established between the remote control and the system. This can trigger and worsen the malfunction.

                3. Dead Remote Control Battery: This is a classic type of malfunction. Sometimes it goes unnoticed because it's not considered important. If the remote control battery dies or weakens, it loses its function. Even a low battery can affect the operation of the remote control and the locking system.

               4. Door Lock Mechanism Jamming: Dust accumulation, wear and tear, rust, and lack of lubrication can cause the mechanism to jam. The lock system will be unable to engage due to the jam. The remote control will be inoperative in such cases.

               5. Vehicle Control Unit (ECU) Malfunction: If there is a malfunction or damage to the vehicle's ECU, the locking system will automatically shut down. The electrical components will absolutely not work until the ECU module is repaired and the malfunction is corrected. This directly affects the locking system, causing it to move uncontrollably.

                                                         Troubleshooting      

• Central locking motor replacement or repair. 

• Fuse box check and electrical current correction. 

• Remote control battery replacement, or replacement of the remote control itself. 

• Service check and all maintenance of the vehicle's ECU (engine control unit).

Clutch Disc Wear Failure

 

                                   Clutch plate failure can become a threat to the vehicle over time. While noticeable signs of failure appear, ignoring them can lead to significant damage. Clutch plate wear causes a decrease in vehicle performance and makes gear changes extremely difficult. It is necessary to accurately identify the causes and symptoms of clutch plate failure and approach the solution accordingly. It directly affects important parts of the vehicle and, if left unchecked, can spread to other areas.

                                                           Signs of Clutch Disc Wear 

                           1. Increased Engagement Point: If the pedal starts engaging from its highest point, it indicates a wear problem. If gear changes occur without fully depressing the pedal, the wear fault has progressed to its initial stage.

                         2. Clutch Slippage: If the engine power increases but the speed remains at the same level, the clutch is slipping. As the slippage progresses, it will cause clutch plate wear.

                       3. Difficulty Shifting Gears: This is the most noticeable symptom of a malfunction. Shifting gears becomes excessively difficult, and sometimes the gear may slip into neutral when the clutch is released. In such cases, clutch wear is a prominent symptom.

                       4. Stiffening Clutch Pedal: If the pedal becomes stiff when pressed with the foot, this is due to clutch plate wear. As the clutch plates wear down, the clutch pedal becomes stiffer.

                        5. Burning Smell: Due to excessive friction and wear on the brake pad surface, a sharp burning smell is noticeable. If the daily brake pad smell increases, it means the brake pad wear problem has progressed.

                        6. Shaking During Start-up: If the vehicle struggles to start or shakes excessively, the clutch plates have begun to wear out. This wear prevents the vehicle from starting smoothly and results in a decrease in vehicle performance.

                                                            Factors that Cause Wear and Tear    

                        • Using the Half-Clutch

                       • Stop-and-Go in Heavy Traffic

                       • Harsh and Unnecessary Starts

                       • Driving with Heavy Loads and on Inclines

                                                   Solution to Brake Pad Wear Problems     

                If a clutch disc wear failure occurs, the entire clutch assembly needs to be replaced. The problem, caused by disc wear and friction, can spread from the clutch cable to other parts. Replacing only the disc will not solve the problem. Installing a disc compatible with your vehicle will resolve the issue; using discs from different brands will cause the same problem to recur. Using discs from less than reputable brands can lead to incompatibility between the clutch and the disc. This can cause gear changes and vibrations in the vehicle. Choosing a disc that is closest to your vehicle's brand and model will be effective in resolving the problem.
