What Causes the Noise After the Car Engine Stops?

There are both normal and abnormal reasons for the noise after the car engine stops. Normal reasons: 1. Cooling sound of the catalytic converter: The normal working temperature of the catalytic converter is between 400 to 800 degrees. After turning off the engine, its operation gradually stops, and the temperature drops, causing the internal metal parts to expand and contract, resulting in noise. 2. Cooling sound of the exhaust pipe: During cold idle, the exhaust pipe also expands and contracts due to heat, producing noise. 3. Cooling sound of the turbo: Normally, the exhaust gas temperature reaches 600 to 700 degrees, accelerating the friction-generated heat from the turbo's rapid rotation. After turning off the engine, the heat expansion and contraction are quite noticeable, leading to noise. Abnormal reasons may include loose screws at the catalytic converter interface, damaged carbon canister solenoid valve, or poor operation of the starter motor.

Why do the handbrake light and ABS light come on at the same time?

The simultaneous illumination of the handbrake light and ABS light may indicate a malfunction in the ABS system or handbrake. It is recommended that the owner immediately inspect the ABS system. On the dashboard, there is an indicator light for the ABS system. When the ABS system is functioning, the indicator light will blink. If the ABS system malfunctions, the indicator light will remain continuously lit, and the driver should take the vehicle to a repair shop for inspection. If the ABS system fails, the wheels may lock up during braking while driving, which is extremely dangerous. Additionally, if the handbrake is not fully released, the handbrake light will also stay on. The ABS system, or Anti-lock Braking System, is a standard feature in almost every vehicle. This system prevents wheel lock-up during emergency braking.

What are the symptoms of low manual transmission fluid?

The symptoms of low manual transmission fluid are: 1. Jerky feeling when shifting gears, with rough gear changes; 2. Difficulty in shifting gears, feeling dry and stiff; 3. Vehicle jerking during gear shifts. In severe cases, the increase in engine RPM does not correspond to the increase in vehicle speed when pressing the accelerator. This means the RPM rises normally, but the speed does not increase accordingly, feeling as if the gear is not engaged properly, and starting the vehicle becomes particularly strenuous. For the transmission, the lack of oil increases friction, causing the transmission to overheat, leading to gear surface damage, transmission burnout, and reduced transmission lifespan. Transmission fluid serves to clean, lubricate, cool, and seal the transmission, maintaining the cleanliness of the gear system and providing lubrication and extended lifespan to the transmission components.

What are the symptoms of low oil in a manual transmission?

Manual transmission low oil symptoms: There will be abnormal noise from the transmission, difficulty in shifting gears, and in severe cases, it can burn out internal transmission components, leading to the transmission being scrapped. A manual transmission, also known as a mechanical gearbox, requires manually moving the gear lever to change the gear meshing positions inside the transmission, altering the gear ratio to achieve the purpose of shifting. The transmission mainly refers to the car's gearbox, which is divided into manual and automatic types. The manual transmission mainly consists of gears and shafts, achieving speed and torque changes through different gear combinations; the automatic transmission (AT) is composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations.

What to Do When Car Windows Fog Up?

Press the defogger button, turn on the air conditioning (A/C) switch, set the temperature to the lowest, and turn on the external circulation to defog. You can use either cold or warm air to defog car windows, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it is important to note that warm air should not be used for defogging on rainy days, as it may initially worsen the fog. When car windows fog up, always use the external circulation. The reasons for car windows fogging up: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface of the lower-temperature side will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on promptly, the exhaled air has high humidity, and the windshield will quickly fog up. At this point, you can turn on the air conditioning to blow cold air onto the windshield, using the dehumidifying function to remove the fog quickly. If the humidity is too high and the air conditioning is not effective enough, you can slightly open the windows to quickly reduce the humidity inside the cabin. Of course, combining both methods will yield faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, use warm air to blow hot air onto the glass, quickly raising the temperature of the front glass and reducing the temperature difference between the inside and outside surfaces of the window. This can prevent excessive fogging on the windshield. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to remove all the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. Do not set the air conditioning temperature to the coldest position, as this may cause frost to form on the outside of the windshield over time. Spraying Anti-Fog Agents for Prevention: Spray a small amount of defogging agent onto the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed on the glass, effectively preventing water vapor from condensing and forming fog. This is especially suitable for cold winters. Alternatives to anti-fog agents include dish soap, soapy water, glycerin, alcohol, or salt water. After applying, let it dry and then wipe off excess residue with a chamois or soft dry cloth. This will keep the car windows fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not too heavy, you can open the windows on both sides to create airflow between the inside and outside of the car, reducing the temperature difference and allowing the fog to disappear slowly. The principle of this method is the same as using cold air from the air conditioning. The downside of opening windows for airflow is very obvious—it cannot be used during rain, snow, on highways, or when the fog is heavy. Rear Windshield Heating: Most cars have a rear windshield electric heating function, although the button positions may vary, the function is the same. Turn on the windshield heating switch, and the fog on the rear windshield will disappear in about a minute.

How Often Should Manual Transmission Fluid Be Changed?

Manual transmission fluid should be replaced when the vehicle reaches approximately 30,000 kilometers. If the vehicle is not used frequently, it can be changed at around 50,000 kilometers. Transmission fluid is the lubricant used in the transmission system, and its primary function is to lubricate the various components inside the transmission, ensuring it operates smoothly. The main purposes of transmission fluid are to keep the gear-shifting system clean and to lubricate the transmission components, thereby extending their lifespan. Due to differences in transmission design, transmissions are categorized into manual and automatic types. Each transmission design has specific technical requirements, and even the same transmission model installed in different vehicle models will have its own designated specialized transmission fluid as specified by the manufacturer.
