Cars should be carefully maintained in winter. Because the temperature is very low, the parts of the car are fragile. If you do not pay attention to the use of the method, it is likely to be the problem. You should be careful to use it to protect your car. This article will introduce the winter maintenance of car knowledge.
The winter maintenance of the engine
Cars often have trouble starting in winter. This is because the external temperature is too low, resulting in increased oil viscosity, resistance, engine starting difficulties also appear.
In such a situation, its fundamental cause is the engine temperature is too low. In winter, parking should pay attention to the front of the wind, as far as possible against some tall objects to the wind.
The car body and chassis of winter maintenance
To the car body, to meet the arrival of cold, it is necessary to do hairdressing. Waxing your car is a great way to protect your paint as the number of times you brush your car decreases in the winter. After waxing treatment, the body is not easy to touch water, it is not likely to appear frozen into ice condensation beads. A car paint coating containing Teflon peek self polymer can also be added to resist acid rain, acid snow, and saltwater. In winter chassis because of frequent contact with rain and snow, is easy to rust. A conditional word can do rust-proof processing to chassis.
Battery maintenance in winter
The battery is a component that does not undergo cold. At low temperatures, the capacity of the battery is much lower than at room temperature. So before the arrival of winter, it is necessary to supplement the electrolyte and adjust the proportion of electrolyte. Clean up the dirt on the terminal of the battery and apply special grease to protect it to prolong the service life of the battery. If the vehicle is not used for a long time, it is recommended to remove the battery to prevent the battery from icing damage.
The winter maintenance of tires
Winter temperatures are low, so tire rubber tends to harden and become brittle, leading to leakage and puncture. If the tire has an injury and is still on the road, especially at high speed, the injury can expand over time, causing the tire to leak. If the tire is worn, please replace it in time. Also need to pay attention to the tire pressure, the owner must pay attention to the changes in the tire pressure of the car. Unlike other seasons, low tire pressure coupled with thermal expansion and contraction in winter can easily lead to deformation on both sides of the tread.
Maintenance of power supply system in winter
The battery is very “sensitive” too low temperature, and the battery capacity at low temperature is much lower than that at room temperature. Although the batteries are now maintenance-free, there is no need to supplement the electrolyte of the battery and adjust the proportion of the electrolyte. However, before the advent of the cold season, the battery terminal should also be cleaned and coated with special grease to protect, ensure reliable start-up, prolong the life of the battery. If the vehicle is not used in the open air or garage for several weeks, the battery should be removed and stored in a warmer room to prevent battery damage.
