Returning from the Spring Festival Maintenance car focuses on these components

According to the Wuwei Public Security Traffic Police:

Return home from the holiday

Experience the Spring Festival

After the boat is tired and frequently used

A car may appear

One question or another

For example, tires deviate during driving

The body was unusually loud and the steering wheel was shaking abnormally

Problems such as abnormal brake braking

All require special attention

Share today a long drive back

Knowledge of vehicle safety inspection and maintenance

01

Check the oil level

After a long drive, be sure to check the oil level in time, especially for vehicles with many years of use and mileage, there may be a situation of "burning oil".

If the oil consumption is serious, consider replacing components such as valve oil seals and piston rings.

02

Check the chassis for oil leaks or loose screws

When using a car every day, some small stones on the road at high speed will splash up and hit the chassis, sometimes it may hit some pipelines to cause oil leakage, or the bursting of the exhaust pipe, which will cause hidden dangers to the safety of the vehicle; another situation is that the body is too low, and it is easy to rub the chassis.

When inspecting the chassis, the most likely to overlook is the "screw", complex bumpy road conditions are easy to cause the screws on the suspension to loosen, should be checked and tightened the screws of the front and rear suspension, hem arm, and subframe.

03

Check the tires

Tires are parts that come into direct contact with the ground and are subject to sharp objects such as gravel and broken glass.

First check the appearance of the tire to see if there are any nails or damage, if there is a crack or bulge on the side of the tire, consider replacing it, otherwise there is a risk of puncture.

04

Check the brake discs and brake pads

The brake system encounters water after high load use, the brake disc is easy to deform, resulting in abnormal brake use, such as the body and steering wheel shaking when braking, the brake disc must be replaced; the brake disc and the brake pad are badly worn or scratched, and then need to be repaired or replaced in time.

05

Check the air filter

If the friends drive to the dusty countryside or suburbs, they must replace the air filter in time.

An air filter is a barrier to the entry of air into the engine. If air enters the engine without filtration, it will accelerate the wear of the piston group and cylinders, which will seriously affect the life of the engine. When the air filter is heavily dirty, the intake resistance increases, resulting in a decrease in engine power.

06

Check the lighting system

Turn on the headlights to detect whether the high and near lights can be switched normally, and whether the rear tail light running lights, brake lights, and front and rear turn signals are normal.

Check whether the lights and bulbs outside the car have burned out faults, and if there is a burn out fault, they need to be replaced immediately. Although surface cracks do not affect the illumination performance of the headlamp, moisture will seep into the luminaire along the cracks, which will reduce the service life of the bulb.

07

Four-wheel positioning

Complex road conditions and bumpy driving environment are easy to cause the wheel inclination, inclination and elopement value of the vehicle to change, resulting in heavy steering, trembling, deviation, incorrect, non-return or unilateral wear of the tire, when driving, the car feels floating, bumpy, rocking and other phenomena.

If necessary, the vehicle is positioned on four wheels. Four-wheel positioning can effectively maintain the steering wheel upright when traveling straight, maintain straight driving and driving smoothly, thereby improving driving safety and reducing tire wear.
