Basic knowledge of automobile maintenance that must be known

As we all know, car maintenance can ensure the excellent performance of vehicles and increase driving safety. However, the friction generated in the process of automobile use will cause losses to automobile parts.

If drivers know and master certain knowledge and skills of car maintenance, they can better protect their cars and effectively extend their service life. So how to maintain it is correct?

0 1 check

observational check

Before driving, look around the vehicle and check whether the paint surface is scratched, the lampshade is damaged, the body is tilted, the chassis is leaking oil/oil, and the door/hood/back door/glass is damaged.

Liquid level check

Check whether the engine oil level, brake fluid level, windshield washer fluid level, power steering fluid level and coolant level are normal.

tyre

Cold state: check tire pressure and state (wear, bulging, aging cracks, hard injuries, etc.). ) and check the spare tire.

Engine front cabin

Check whether the pipe is worn or folded. Check the lighting of lamps and lanterns, and check the indicator light of instruments.

02 maintenance

clean

Clean the exterior of the vehicle, clean the interior of the engine compartment (oil and other dust left in the radiator, condenser and engine), clean the interior of the vehicle and clean the rear door. (Tips: Cleaning the vehicle with clean water can protect the paint surface of the vehicle to the maximum extent. )

Chassis anticorrosion

Check the anti-corrosion and protective layer of the chassis regularly, and repair it at the sales service provider if necessary.

Paint protection

In order to ensure the durability of automobile paint surface, it is necessary to remove the substances that damage the paint surface in time, such as bird droppings, resin, insect residue, scorched oil stains, road deicing salt, industrial falling objects and so on. Waxing once or twice a year helps to keep the paint smooth. (Note: ① Don't let the polishing agent touch the plastic surface, otherwise it will be difficult to clean. ② Don't clean the car in strong sunlight. )

radiator

It is recommended to clean the radiator surface once a year. After the engine is turned off, clean the radiator fins with compressed air or water to blow away insects, leaves and other sundries. The pressure of air and water should not exceed 150kPa. If the pressure exceeds 150 kPa, the radiator fins will be damaged.

capacitor

When the engine is off, clean the condenser by blowing air from the back to the front through the radiator.

tyre

Check the tire surface regularly for cuts, foreign bodies and uneven wear. The uneven wear of tire tread may be caused by inaccurate wheel positioning. If the wear depth reaches the limited value, the safety will be greatly reduced, and it is recommended to replace it.

Leather finishing and maintenance

Wipe the leather surface with a damp cloth and towel and dry it with a clean soft cloth. Very dirty surfaces can be cleaned with neutral detergent. During normal use, it is recommended to maintain the leather once every six months and use a special conditioner for leather. When maintaining, don't rub the leather surface too wet, especially don't let the liquid penetrate into the cracks.
