Car maintenance is done seasonally, just like people wear clothes. So what are the methods for winter car maintenance? Let's first take a look at the topic of cars being heated in place and the engine idling causing damage to the car.

It will be winter in a while, and many drivers do not understand how to maintain and drive their vehicles safely in winter. According to the statistics of the municipal highway law enforcement department, there have been more than 50 traffic accidents caused by improper maintenance of vehicles since the New Year. A senior mechanic teaches you winter car maintenance tips.

Car overheating in place, engine idling causing damage to the car

Car maintenance experts say that with the decrease in winter temperatures, it is necessary to warm up the car. However, most car owners believe that it is best to start the car early in the morning or for a long time without using it. After starting the car, idle it in place and wait for three to five minutes before driving on the road.

According to statistical data, over 90% of the wear on engine components is caused within three minutes of starting a cold car. Therefore, in winter, especially in the extremely cold winter, idling and warming up the car in place can easily damage the engine. It is recommended that car owners use a low-speed and slow driving method to warm up the car.

Winter car maintenance knowledge

The main reason for a hot car is that after being parked for a long time, the engine oil flows back into the oil pan at the bottom of the engine. Therefore, after ignition, the upper part of the engine is in a state of no oil and lack of lubrication. It takes about 30 seconds after starting to transport oil to the piston, connecting rod, crankshaft and other components that need lubrication the most due to the operation of the oil pump.

Although it is necessary to warm up the car, idling the car in place is not advisable because only the engine is running and the rest of the parts are not, and kinetic energy cannot be converted. Only by slowly driving for a period of time after hitting the road can the engine working conditions be improved.

The correct way to warm up a car is to hit the road 30 seconds to one minute after starting, but at this time, do not drive at high speed. Keep the speed low, and the engine speed should not exceed 3000-3500 revolutions per minute, usually kept at 2000 revolutions per minute. Otherwise, the severe wear and tear on the engine and gearbox cannot be restored. After the engine temperature rises to normal operating temperature (which may take 3 to 5 minutes), resume normal driving.
