Car University: Preparing for the holiday car special care strategy

I. Body cleaning inspection

First, the exterior parts such as the chassis, tire rims, front and rear lights, bumpers, door and window glass should be thoroughly cleaned, and then the exterior of the body should be inspected With or without scratches. Many car owners are unfamiliar with the road surface or some road conditions are poor, which may cause obvious scratches and dents on the exterior of the vehicle, especially in the front bumper. The cracks in the paint layer caused by some collisions are not very large and do not affect the appearance of the vehicle, so they are ignored. When the metal under the paint begins to rust, it can be seen from the outside, and the internal metal layer has been severely rusted. When dealing with it, it is necessary to “break the muscles and bones”.

Second, check the air-conditioning system

In order to enable the air-conditioning to start smoothly in summer, it is necessary to check the air-conditioning, and repair it in time if any problems are found. The owner of the car can test the limit refrigeration of the air conditioner through the temperature sensor, as long as it can be equal to the normal temperature, otherwise, it is necessary to go to a professional after-sales service station for inspection and maintenance. Generally, the limit refrigeration of automobile air conditioners is relatively fixed. For example, European cars can reach 3 ??C.

Third, check the tires

Tires are the only parts of the vehicle that touch the ground, so there is a higher chance of injury. Owners can check their tires for obvious trauma and scratches. If there are obvious scars on the sidewall, it is best to replace it, because the sidewall of the tire is thin and the pressure it bears is limited, and the chance of having a scratched tire will be greatly increased. During maintenance, first check the tire pressure, wear condition, whether the nut is loose or fall off, and remove sharp debris such as inserts and iron nails between the twin tires or on the tread. If the car deviates or swings when driving, it is necessary to re-do the four-wheel alignment or dynamic balance.
