Maintenance of winter car cooling system is key

In winter, the atomization conditions of gasoline are poor, and it is generally not easy to start. It is also impossible to immediately switch to normal operation after startup. Therefore, during winter maintenance, it is necessary to clean and clear the oil passages and air passages, and check the working conditions of the throttle valve, choke valve, acceleration pump, and vacuum pump, and should be adjusted to the best condition. The circuit is mainly to check the platinum gap of the distributor and the electrode gap of the spark plug. The distributor platinum contacts should be clean and free from ablation, the contact surface should be above 70%, and the gap should be between 0.3 and 0.45 mm.

In the cold winter, the maintenance of the cooling system is critical, first of all to check the cooling system from the appearance, such as: the water drain hole of the pump, the thermostat joint, the upper and lower water pipe joints, the water outlet, the water tank cover and the water tank, etc. There is no trace of leakage at the site. When everything is OK, check the freezing point of the antifreeze. In addition, check the thermostat. If the thermostat does not work properly, the engine will be in a low-temperature state for a long time. This will increase the wear of the engine and shorten the life of the engine. Winter tire rubber will also become hard, the first thing to pay attention to is the tire pressure; secondly, pay attention to the pattern of the tire.
