How Car Cooling Systems Work

A car cooling system works by circulating fluid through the pipes and passages in the engine. When the liquid flows throughthe high-temperature engine, it will absorb heat, thereby reducing the temperature of the engine. after the liquid flows throughthe engine, it will flow to the heat exchanger or radiator), and the heat in the liquid will be dissipated into the air through theheat exchangerMaintenance content of car cooling system:1. Selection of cooling water: River water with low hardness should be used such as well water, which should be boiled andsoftened before use. It is best to use antifreeze2. Pay attention to the technical status of each part: if the radiator is found to be leaking, it should be repairedfound that the water pump and fan are rotating, swinging or making abnormal noise, it should be repaired in time. If the engine isfound to be overheated, it should be checked in time for water shortage. If the thermostat is not working properly and the engineoperating temperature is too high or too low, it should be repaired or replaced in time;3. Inspection and adjustment of the fan belt tightness: If the fan belt tightness is too small, it not only affects the coolingir volume and increases the engine workload, but also accelerates the wear of the belt due to slippage. If the belt tightness istoo large, it will accelerate the wear of water pump bearings and generator bearings. Therefore, the belt tightness should bechecked during use, and adjusted if necessary. If it does not meet the requirements, it can be adjusted by changing the positionof the generator and the adjusting arm;4. Regular cleaning of scale: After the engine has been used for a certain period of time, scale will be deposited in the waterank and radiator to affect heat dissipation, so it should be cleaned regularly. The cleaning method is to add enough cleaningliquid to the cooling system and start the engine after soaking for a period of time. After running at low and medium speed forcertain period of time, release the cleaning solution while it is hot, and then rinse it with clean water.
