How to maintain the cooling system
1. It is recommended to use antifreeze.
2. If the radiator is leaking, it needs to be repaired. If the water pump or fan oscillates or makes abnormal noises, it should be repaired in time. If the engine overheats, you must quickly check if there is a lack of water, stop the engine. After cooling, add sufficient cooling water. If the thermostat does not work properly and makes the engine operating temperature too high or too low, it should be repaired or replaced in time.
3. Improper tension (tightness) of the fan belt will affect the normal operation of the generator and water pump. When the fan belt is too loose, the belt will partially slip in the spleen groove, causing the motor to overheat and reduce the power generation rate; when it is too tight, the belt rollsgenerator and water pump bearings will speed up; to carry.
4. After a certain period of engine use, scale will be deposited in the water tank and radiator, which will affect heat dissipation. Therefore, it must be cleaned regularly. To add enough cleaning fluid to the cooling system and let it soak for a while, start the engine and run it at low to medium speed for a while, release the cleaning fluid while it is hot, then rinse it. with clean water.
The cooling system includes the front fan, radiator, water tank, water pump, water lines, water jacket in the engine and a very important thermostat. When the engine temperature is not high, cooling water only. flows. Little circulation, i.e. water does not pass through the thermostatand the radiator. When the water temperature reaches a certain level, the deformed metal in the thermostat opens due to the high temperature. passes through high circulation and passes through the radiator. Ensures normal operation of the cooling system.
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 systeme exhaust, but some of the heat remains in the engine, causing the engine temperature to increase.
3. 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. 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, itwill not only affect the cooling air volume and increase the workload of the engine, but also accelerate. belt wear due to slipping. If the belt is too tight, it will accelerate wear on the water pump bearings and generator bearings. Therefore, during use, the tightness of the belt should be checked and adjusted if necessary. If the conditions are not met, you can change the generator and adjust the position of the adjustment arm. ?
