Vehicle maintenance in winter

In winter, the weather is cold, and if the vehicle is not started for a long time, some failures may occur. Before leaving the vehicle, a detailed inspection of the vehicle should be carried out to ensure that all parts can work normally before departure.

1. Check whether various oils need to be replenished. Including coolant, oil, urea, fuel, glass water, etc.; if there is a decrease, replenish it in time, and the addition of various types of oil should be kept between the upper and lower limits; in addition, it is necessary to check whether there is leakage of each component, if there is leakage It is best to contact a service station for repairs.

2. Check the battery power. If the vehicle is not started for a long time, the battery will lose power, and it needs to be charged in time to start smoothly.

3. Check the gas circuit and oil circuit. Water in the oil circuit may cause the vehicle to become weak. Before leaving the car, you can use the hand oil pump or electronic oil pump to pump oil to check whether the low-pressure oil circuit has air intake; Oil and other impurities to avoid blockage of the gas path; finally, remember to clean up the water in the coarse filter collection cup in time to avoid the deposition of moisture and impurities.

4. Check various gas paths and pipelines. Check whether various lines and pipelines have cracks and aging phenomena, and whether the sockets are loose, and promptly investigate and deal with hidden dangers.

5. Check the tire pressure. If the vehicle is parked for a long time, the tire pressure may change. Before leaving the vehicle, you should carefully check each tire of the vehicle to check whether the pressure is consistent, and keep the tire pressure on both sides as consistent as possible to prevent unnecessary tire wear. In addition, you need to check Check whether the tire has cracks and air leakage, and remove the gravel mixed in the tire pattern.

6. Check the brake system. The brake system is very important for driving safety. The brake system must be overhauled before leaving the car. Vehicles without automatic adjustment arms need to manually adjust the brakes. Vehicles with automatic adjustment arms need to check whether the adjustment arms need to be lubricated, and Check the air chamber return spring, brake shoe tension spring, etc. for problems; in addition, check the wear degree of the brake pads and replace them in time.

7. Pay more attention to the three major items. There are generally no problems with the three major parts, but once a problem occurs, it may seriously affect the normal operation of the vehicle. Before leaving the car, everyone should also check the three major parts, and pay attention to whether there is abnormal noise after starting.

8. The steering system also needs to be checked. Many truck drivers may ignore this part of the inspection, mainly to check the lubrication of the mechanical connection of the special system, whether the steering oil and filter element are sufficiently clean, whether the steering rod and pressure bearing are in normal condition, and shake the steering wheel up and down to check whether there is a gap, etc.
