What parts need to be replaced during a 30,000-kilometer car maintenance?

Is it normal to have water vapor inside the car taillight?

It is abnormal to have water vapor inside the car taillight. Avoid inferior bulbs: The performance of bulbs is crucial as it affects nighttime illumination and driving safety. High-quality headlight bulbs are a strong guarantee for safe driving. Perform regular maintenance: Cars require regular maintenance, such as checking whether the oil and oil filter need replacement and whether the brakes are functioning properly. Similarly, headlight bulbs should also be inspected periodically for integrity and replaced promptly when necessary. After driving approximately 50,000 kilometers or around 2 years, the brightness of headlight bulbs tends to diminish. At this point, it is advisable to have them inspected at a 4S store. If the brightness is insufficient, it is best to replace the bulbs immediately, preferably replacing both sides simultaneously to maintain uniform brightness.

Is it normal for the ABS light to come on and then go off after restarting?

ABS light comes on and then goes off after restarting. If the ABS warning light is on, it is recommended not to continue driving. Because the ABS light indicates a malfunction in the vehicle's anti-lock braking system, during emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. The role of ABS: To maximize the effectiveness of the brakes, reducing braking time and distance. It effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. It allows steering during emergency braking, providing excellent steering control. It avoids severe friction between the tires and the ground, reducing tire wear. How ABS works: During braking, ABS quickly determines the wheel lock-up status based on the speed signals from each wheel speed sensor, closing the normally open input solenoid valve on the wheel that is starting to lock, keeping the braking force constant. If the wheel continues to lock, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to drop rapidly due to the direct connection to the brake fluid reservoir, preventing the wheel from fully locking due to excessive braking force. This keeps the braking state at the optimal point (slip rate S of 20%), achieving the best braking effect and the highest driving safety.

Does Coating Liquid Damage the Car?

Coating liquid can damage the car. Reduces the thickness of the car paint: The coating agent chemically bonds with the car paint, which can cause some damage. Before applying the coating, the car paint needs to be polished, and polishing itself is harmful to the paint as it reduces its thickness. Additionally, the coating agent chemically fills the gaps between the paint molecules, which can disrupt the original molecular structure of the paint. Short duration of effectiveness: The coating agent's effects are short-lived, requiring multiple applications. Each application necessitates polishing the car paint again, which gradually makes the paint thinner. Thinner paint makes the car more susceptible to scratches.

Why Doesn't the Fuel Gauge Rise After Refueling the Car?

There are several reasons why the fuel gauge doesn't rise after refueling: instrument damage, wiring damage, or fuel float damage. Inspection methods: Check the wiring. If normal, remove the fuel float and move it up and down manually. If it moves, the fuel float is damaged. If it doesn't move, check the fuel gauge. Fuel gauge: The fuel gauge is used to indicate the amount of fuel remaining in the car's fuel tank. It can be either a pointer or a digital display. The fuel gauge consists of a fuel level indicator with a voltage regulator and a fuel level sensor. The low fuel level warning device alerts the driver when the fuel in the tank falls below a certain level.

Is It Normal for a Car's Exhaust Pipe to Have Black Carbon Deposits?

It is not normal for a car's exhaust pipe to have black carbon deposits. Poor spark plug condition: When the car is in a cold-start state, if the spark plugs are not functioning properly, the air-fuel mixture will not burn completely, resulting in excessive black smoke. Oxygen sensor malfunction: If the engine has been used for too long, its overall performance may degrade, causing the car to inject fuel without properly mixing it with air for combustion, leading to excessive black smoke. Incorrect engine timing and ignition timing: If the engine timing and ignition timing are misaligned, this timing discrepancy will prevent oxygen and engine oil from fully mixing and burning. Other possible causes include a faulty temperature sensor or clogged fuel injectors.
