The car needs great maintenance when it travels 40 thousand kilometers. Do you know what to replace?

Hello, I'm Feng Zi, and I'm an auto mechanic. Car maintenance is my daily work. In fact, in the eyes of our maintenance workers, there is no such thing as major maintenance. What we do is an acquaintance's car, paying attention to phased maintenance, and what kind of maintenance is done at any kilometer. An unfamiliar car owner or a car owner who rarely enters the store, you tell him to do a lot of projects, but he doesn't recognize it, thinking that you want to make his money. But out of a sense of responsibility, we will still tell the owner the problem, and the final decision is still in the owner himself.

40,000 kilometers of maintenance actually does not need too many projects. At present, the mileage of a family car 1 year is about1-20,000 kilometers. Counting 40 thousand kilometers of cars, there are not many years. Many projects are mainly based on inspection. The purpose of inspection is to confirm a basic condition of the vehicle, and the service life of the next wearing parts on the vehicle can be predicted through the current vehicle condition.

First, you need to change the oil and oil filter every time you do maintenance. Replace the air filter element and air conditioning filter according to the use environment. It is suggested that the air filter should be replaced at least once every 1 year, and the air conditioning filter should be replaced once every six months. These two filter elements directly supply air, one is responsible for air passing through the engine and the other is responsible for air filtration in the cab.

Second, the gasoline filter, this is divided into built-in and external. It is suggested that at least 20,000 kilometers should be replaced with external parts and 40,000 kilometers with internal parts. At present, the quality of domestic gasoline is not particularly good, so it is better to change it several times. Especially those engines that eat flour and rice, we should pay more attention and try to refuel at regular gas stations such as Sinopec.

Third, the suggestion of brake maintenance is to do it once every 20,000 kilometers. Although some people think the frequency is a bit high, experience tells us that safety is no small matter. Brake maintenance is more than just polishing brake pads. The purpose of brake maintenance is to check whether the piston of the brake pump leaks oil or is stuck, and whether the piston pin is short of oil and worn.

Fourth, it is suggested to change the position every 30,000-40,000 kilometers. The purpose of transposition is to make the tire wear more uniform. At present, most cars are still driven by front wheels. This causes the front wheels to wear faster than the rear wheels. Transpose regularly, so that the front wheel will not wear to the limit and the tread of the rear wheel is still very new.

Fifth, replace the spark plug as appropriate. If the front has not been replaced, it is necessary to remove it this time to check the electrode gap and confirm the electrode gap to calculate how many miles the spark plug can still use.

Sixth, throttling, throttling also depends on the situation. Personally, don't clean the throttle for many kilometers. If it is not very dirty and there is a lot of carbon deposit, cleaning is not recommended.

Seventh, 40,000 kilometers of coolant should be replaced. Although some cars look at the bright color of coolant, this one must be replaced regularly. Coolant has many functions and can be used for several years once replaced. Don't let the engine cooling system go wrong because of a little money.

Eighth. If the brake fluid has not been changed before, it needs to be changed. Manual transmission oil also needs to be changed. In addition, check whether there is oil leakage in all parts of the chassis and whether the rubber sleeve is worn and aging.

In fact, the car is a prototype, not a repair. After maintenance, it is also worry-free to use. One more thing, if conditions permit, I personally suggest that the car should be fixed-point maintenance. You frequently change repair shops or mechanics, and he doesn't know what maintenance you did last time. This may lead to excessive maintenance of your car.

I am Feng Zi, and I am a repairman. Car maintenance problems can be concerned or commented.

Basically, all models of 40,000 companies have to be overhauled.

Cleaning throttle, air intake and injector, three-way catalysis, carbon deposition in cylinder, and cleaning engine lubrication system;

Replace spark plug, oil filter, antifreeze, directional oil (not needed for electronic power assist) and brake oil;

Check the chassis, brake pads and steering mechanism, and do four-wheel positioning;

Manual transmission oil change;

Automatic gearbox: domestic car replacement, joint venture car replacement of 50 thousand kilometers, all imported cars according to the model!

Brother Hummer lets you know more about cars and repair them. Dont Ask For Help, you will never be fooled again!

Dear theme, hello!

What should be changed is:

Oil and oil filter, air filter, air conditioner filter, gasoline filter (ask the owner where to refuel to determine whether to replace or extend it), vehicle brake fluid, gearbox oil, spark plug. If it is a four-wheel drive, the rear axle oil should be changed, and the antifreeze should be inquired to record whether to replace it.

Tires need to be replaced according to the age of the car and the actual wear and damage of the tires. Use the battery detector to check whether the battery can continue to be used.

The normal maintenance of 40,000 kilometers is mainly to replace engine oil, three filters of engine oil and three filters of gasoline, and the first two should be replaced during normal maintenance. It is no problem to change the gasoline filter every tens of thousands of kilometers.

The other is to test the brake pads to see if it is necessary to replace them. Check the spark plug and look at the throttle. If necessary, you can clean the throttle.

Nothing else, 40 thousand kilometers is not much. Under normal circumstances, these things don't need to be replaced as long as there is no problem in testing.

It's usually 50 thousand kilometers

Oil change, four filters, gearbox oil, spark plug, brake oil, antifreeze, booster pump oil, throttle cleaning and so on are basically so much.

Normal 40,000 km car maintenance items include: engine oil, three filters, spark plug inspection, brake pad inspection,

Oil change, four filters, gearbox oil, spark plug, brake oil, antifreeze, booster pump oil, throttle cleaning and so on are basically so much.

I haven't had major maintenance for a long time, so I followed normal maintenance, and major maintenance has long been eliminated.

Every brand has different requirements, depending on what brand of car you are.

No, it would be nice if the machine filter, air filter, engine oil and coolant were changed regularly.
