1. Car engines operate best at moderately high temperatures. If the engine cools, it will accelerate the wear of parts, reducing engine efficiency and emitting more pollutants. Therefore, another important role of the cooling system is to warm up the engine as quickly as possible and maintain a constant temperature. 2. Another important role of the cooling system is to warm up the engine as quickly as possible in order to maintain a constant temperature. Fuel burns continuously in a car engine. Most of the heat generated during the combustion process is removed from the exhaust system, but some of the heat remains in the engine, causing an increase in engine temperature.
3. Selection of cooling water: River water with low hardness, such as well water, should be boiled and softened before use. He isBetter to use antifreeze. 4. Pay attention to the technical condition of each part: if the radiator leaks, repair it. If the water pump and fan oscillate or make abnormal noise, they should be repaired in time. When the engine overheats, quickly check for water shortage. If the engine runs out of water, stop it. After cooling, add sufficient cooling water. If the engine temperature is too high or too low due to abnormal operation of the thermostat, the thermostat should be repaired or replaced in time.
5. Check and adjust the fan belt tightness: If the fan belt tightness is too loose, it will not only affect the cooling air volume and increase the workload of the engine, but also speed up. belt wear due to slipping. If the belt is too tight, it will accelerate the wear of the water pump bearings and the engine bearings.generator. Therefore, during use, the tightness of the belt should be checked and adjusted if necessary. If it does not meet the requirements, it can be adjusted by changing the position of the generator and the adjustment arm. ?
