Professional RV Modification Experts Teach You How to Inspect And Maintain Your Vehicle in Winter

Vehicle appearance inspection and maintenance

1. If your car has obvious scratches, spray paint outside in time. Because the role of paint is not only beautiful, its more important role is rust prevention;
2. Choose a sunny day to wax the whole car to maintain the car paint. Do not polish the damaged parts many times. It is recommended to paint again;
3. In winter, the rubber of the tire becomes hard and brittle, which not only reduces the friction coefficient, but also causes air leakage and puncture. Check whether the tire has obvious external injuries and scratches, and whether the tire pressure is up to standard. Pay attention to frequently remove tread inclusions and replace worn tires. It is a good idea to use winter tires in ice and snow areas;
4. Don't forget to check the lights. If the headlight bulb becomes dim, it needs to be replaced in time, and the fog lamp should not be ignored. The brake lights are easily damaged and should be checked and replaced in time;
5. When using glass cleaning fluid, it is better to buy winter-specific products in cold areas;
6. If the wipers have not been used for a long time, they need to be replaced. There are a lot of rainy and snowy weather in winter, and visibility is not very good, so be sure to pay attention to the field of view of the windshield.

Vehicle performance testing and maintenance

1. As the temperature changes, the general water content increases
As the air temperature decreases, the viscosity of the lubricating oil will also deteriorate. The increase in friction resistance of auto parts during movement will lead to difficulties in cold starting, reduced engine power, and even accidents such as burning tiles and axle sticking. It is recommended to replace the engine oil in winter;
2. It is more difficult to start the car in winter, and the battery is more likely to lose power. The oxide on the battery pole should be removed to ensure good contact and eliminate the hidden danger of starting difficulties. For car owners using rechargeable batteries, the liquid level of the battery electrolyte should also be checked. If the liquid level is below the mark, they need to add distilled water. It is recommended to send the car with insufficient power to the repair shop for charging in time;
3. Antifreeze is usually replaced every two years. In winter, it is recommended to go to the repair shop for a freezing point test to determine whether the antifreeze needs to be replaced;
4. The heating system should be checked and repaired in time;
5. The brake fluid is safe and cannot be careless. Good quality winter brake fluid needs to be replaced.

Chassis performance test and maintenance

1. Carefully check the suspension and front axle for oil leakage, etc. On flat ground, press your body on the four wheels of the car to see if there is any abnormal noise;
2. Also check the brake pads, brake pads and brake drums. Including the handbrake system. If there is no problem, use the air gun in the repair shop to clean the dust on the drum brake. Uneven brake pads should also be polished to make them flat.
