In recent days, a large area of ​​the country has cooled down. While we are adding clothes, we should also test and maintain the car for our own car. As the saying goes, three separate, seven points raised, if the car is not well maintained, performance will be greatly affected.
If the car has obvious scratches and scratches, external painting must be done in time. Because the role of paint is not only beautiful, its more important function is rust prevention.
Pick a sunny weather and do a full car waxing to conserve the car paint surface. For those that are already defaced, do not polish many times. It is best to do a new paint.
Tire rubber becomes relatively brittle in winter. Not only does the coefficient of friction decrease, but also it is easier to leak and puncture the tire. Check whether the tire has obvious trauma or scratches and whether the tire pressure is standard. Pay attention to the frequent removal of inclusions in the tread and replace the more worn tires. In snowy areas, using special winter tires is a good idea.
Do not forget to check the lights, if the headlight bulb dims it needs to be replaced in a timely manner, fog lights should not be ignored. Brake lights are relatively easy to damage, but must be checked and replaced.
When using glass cleaning fluids, it is also important to note that it is better to purchase special winter products in colder areas.
If the wiper is used for too long, it must be replaced. Winter rain and snow, visibility is not very good, windshield vision must pay attention.
With the change of temperature, the viscosity of ordinary lubricants will also deteriorate with the temperature and the fluidity will worsen. The increase of frictional resistance during the movement of automobile parts will cause the cold start of the automobile to be difficult, the engine power will decrease, and even the burning of the bearing bush can be serious. In accidents, it is best to change the oil in winter.
It is more difficult to start the car in winter and it is easier for the battery to lose power. The oxides on the battery poles should be removed to ensure that the poles are in good contact and eliminate the hidden dangers of inability to start. For car owners who use liquid-filled batteries, they must also check the liquid level of the battery electrolyte. If the liquid level is lower than the marking line, it must be filled with distilled water. Less than the best car to send a timely repair shop to charge.
Normally antifreeze is changed every two years. In winter, it is best to go to the repair shop to do a freezing test to determine if antifreeze needs to be replaced.
The warm air system must be inspected. If there are any problems, repair it in time.
The brake fluid is safe and must not be sloppy and must be replaced with good quality winter brake fluid.
To carefully detect the suspension there is a front half shaft to see if there is an oil leak and so on. On the ground, use your body to press the 4 wheels of the car to see if there is abnormal noise.
Brake pads and brake discs as well as brake drums are also checked. Includes hand brake system. If there is no problem, use a blower gun in the workshop to clean the drum brake dust. Grind the uneven brake pads to make them even.
In fact, many of these maintenance items can be carried out on a regular basis by the owner of the vehicle. Perhaps many of the owners are busy or ignore the car's care. People say that you don't love cars and cars don't love you. The above-mentioned precautions are actually very simple and not just for the winter. The author still hopes that each owner will develop a good habit of checking vehicles regularly.
