Precautions for Vehicle Maintenance in Winter

Oct. 28, 2020

The low temperature in winter makes vehicles more prone to problems. "Three-point repair, seven-point maintenance" refers to the discovery and elimination of some initial, potential, and hidden faults through active inspection and maintenance, so as to ensure that the vehicle can survive the severe cold winter smoothly.


Engine maintenance

In winter, the fluidity of engine oil at low temperatures deteriorates, and it cannot quickly reach the friction surfaces at the moment of starting. The metal parts lacking the necessary lubrication dry friction with each other, which greatly increases the movement resistance, causing problems such as difficulty in starting the vehicle and easy flameout after starting. These damages to the engine are very great, and it is necessary to replace the lower viscosity oil in time.


Check the brake system

The brake system is very important to the driver's life safety. Although there is a warning system, some of them will turn on the warning light when the brake shoes have been completely worn out. Therefore, the warning lights should not be blindly believed, and the brake pads should be replaced in time. In addition, it is most important to check the brake fluid level regularly, at least once a month.


Check tire pressure

Winter rubber will become hard and brittle, and the friction coefficient will decrease. This requires that the tire pressure should not be too high, but not too low. Low outside air temperature and low air pressure will accelerate tire aging, increase friction between tires and the ground, and reduce tire life.


Correct selection of antifreeze

Antifreeze is mainly to ensure that the engine can work within the normal temperature range. Under normal circumstances, it needs to be replaced twice a year. As far as the choice of antifreeze is concerned, the lower the freezing point, the stronger the antifreeze resistance will be. The freezing point of the selected antifreeze should be 10℃ lower than the lowest temperature in the area.


Regularly check the cooling system

In winter, check whether the radiator, water pump and transmission belt, water pipe, water supply tank and other parts are working properly and whether there is any leakage. If there is damage or malfunction, it is best to repair or replace in time.

Check the sprinkler system regularly

The use of the wiper water spray system in winter will be significantly reduced, but it cannot be ignored, especially in the north. In summer, clear water can be used instead of glass water, but in winter these alternatives may freeze. In the environment below zero degrees Celsius in winter, the antifreeze winter glass water should be replaced.


Body and chassis protection

It is best to check whether the chassis armor is defective and take protective measures for the car chassis. For the car body, coating or mirror glaze, etc., it can resist the erosion of salt water formed by acid rain, snow, and road salt after snow.


The battery is most afraid of low temperature

The battery capacity is much lower in a low temperature environment than at normal temperature. Therefore, before the cold season comes, the battery electrolyte should be supplemented, the density of the electrolyte should be adjusted, and the battery terminal should be cleaned and coated with special grease for protection to ensure startup Reliable and extend battery life. If the vehicle is parked in the open air or garage for more than 25 days or so, the battery should be removed and stored in a warmer room to prevent damage to the battery from freezing.

The above is a few common sense about winter car maintenance brought to you by the number plate frames supplier. I hope you will pay attention to avoid inconvenience to your own travel.
