What should Toyota Corolla maintain when driving 40,000 kilometers?

Generally speaking, the service life of vehicle brake pads is about 4-5 years or 40,000 kilometers. Of course, according to different driving habits, driving environment and speed, the degree of wear is also different. Generally, the brake pads of vehicles that often run at high speed are not worn, and they often drive in urban areas, and the brake pads that are often blocked by traffic are seriously worn. We can check the thickness of the brake pads ourselves. Pay attention to the rear drum brake, which will take a long time to replace.

Check and replace the spark plug.

A good spark plug can generally be used for 2-3 years or 20-30 thousand kilometers, but if the vehicle is running under insufficient power or the vehicle is shaking at an accelerated speed, it means that there may be something wrong with the spark plug and it should be checked as soon as possible.

Clean the throttle and fuel injectors.

Throttle and nozzle are driven for a long time, which are easy to get dirty or have carbon deposits, and need to be cleaned regularly. General vehicles need to be inspected and cleaned when they travel more than 50 thousand kilometers, but the frequency of cleaning depends on their driving environment. When the environment is dirty, cleaning time should be shortened.

Clean the water tank.

When the vehicle travels more than 40 thousand to 50 thousand kilometers, the inside of the water tank is often dirty, which affects the cooling and cleaning of the engine. Therefore, if it is really dirty, the water tank should also be washed. Bian Xiao suggested here not to listen to the shop's bluff casually, but to ask more questions. If the water tank is really dirty, there is no need to clean it.

Change brake oil.

In addition to brake pads, brake oil should also be changed regularly, which can be changed according to brake pads or mileage. Brake oil should be of good quality, after all, the braking system of the vehicle is the most critical.

Pay attention to tires, especially spare tires.

The average life of automobile tires is four to five years. Even if the mileage is very small, the aging phenomenon is very common because the tires are often exposed to the sun. Therefore, it is necessary to check whether the tire should be replaced when the lateral crack is large or the tread pattern reaches the minimum. In addition, don't forget to change the spare tire, although it is not used often, just in case.
