What does a 30,000-kilometer car need to be maintained?

The items that need maintenance for a 30,000-kilometer vehicle include: four filters of engine oil, cleaning of throttle valve, replacement of spark plug and cleaning of air conditioner.

1, four engine oil filters

Four of the four oil filters include: oil filter, air filter, fuel filter and air conditioner filter. The oil filter needs to be replaced every maintenance, while the air filter is recommended to be replaced every 654.38+00,000-654.38+05,000 km, and the fuel filter is recommended to be replaced every 30,000 km. It is recommended to replace the air conditioner once every six months. If you want to save costs, you can subtract air conditioning filtration. However, the fuel filter for 30,000 km maintenance must be replaced, remember.

2. Throttle cleaning

There is no need to clean the throttle before 30 thousand kilometers. If the receptionist of a 4s shop or repair shop recommends this project when the car is 65,438+0,000 or 20,000 kilometers, you can directly refuse it.

3. Replace the spark plug

It's almost time to change the spark plug after driving 30 thousand kilometers. Although the ignition performance of the 30,000 km spark plug has not been completely lost, the ignition performance has been greatly reduced. The deterioration of ignition performance directly affects the phenomenon of vehicle idling jitter, lack of cylinder and weak acceleration The decrease of ignition performance and the increase of engine load are also one of the reasons that affect fuel consumption.

4, air conditioning cleaning

Air conditioning cleaning can clean the dust and dirt in air conditioning pipes. And sterilization effect. This project is free to choose. If the car has never been air-conditioned before 30 thousand kilometers, it is time to do air-conditioning cleaning.
