Automotive water cooling system consists of water pump, radiator, cooling fan, thermostat, compensation bucket, liner water in the engine block and cylinder head, as well as other auxiliary devices. The cooling system works by circulating fluid through the engine's pipes and passages. As fluid circulates through a hot engine, it absorbs heat, thereby lowering the engine temperature. Once the fluid has passed through the engine, it then flows to a heat exchanger (or radiator), where the heat from the fluid is dissipated into the air.
The maintenance content of the automobile cooling system is as follows:
1. Selection of cooling water: River water with low hardness, such as well water, should be boiled and softened before use. It is best to use antifreeze;
2. Pay attention to the technical conditionof each part: if the radiator is leaking, it must be repaired. if it rotates or makes abnormal noises, it should be repaired in time. If the engine overheats, you should quickly check for water shortage. If there is a lack of water, stop the engine. After cooling, add sufficient cooling water. If the thermostat does not work properly and causes the engine operating temperature to be too high or too low, it should be repaired or replaced in time
3. Inspection and adjustment of fan belt tightness: The fan belt tightness is too weak, it will not only affect the cooling air volume, increase the workload of the engine and accelerate the wear of the belt due to sliding. If the belt is too tight, it will accelerate wear on the water pump bearings and generator bearings. Therefore, the tightness of the belt should be checked during use and hascorrected if necessary. If it does not comply with the regulations, it can be adjusted by changing the position of the generator and the adjustment arm;
4. Clean the scale regularly: after using the engine for a while; will be deposited in the water tank and radiator, which will affect heat dissipation. Cleaning should be carried out regularly. The cleaning method is to add enough cleaning fluid into the cooling system, let it soak for a while, start the engine and run it. at low and medium speed for a while, release the cleaning fluid while it is hot, then rinse it with clean water.
