How to Maintain the Car Cooling System?

[BriellaLee]

Here are the methods for maintaining the car cooling system: 1. Selection of coolant: It is best to use river water with low hardness. If well water is used, it should be boiled and softened before use. The best option is to use antifreeze. 2. Pay attention to the technical condition of each component: If the radiator is found to be leaking, it should be repaired. If the water pump or fan is found to wobble or make abnormal noises, they should be repaired promptly. 3. Inspection and adjustment of fan belt tension: If the fan belt is too loose, it not only affects the cooling airflow but also increases the engine workload and accelerates belt wear due to slipping. If the belt is too tight, it will accelerate the wear of the water pump bearing and generator bearing. Therefore, the belt tension should be checked during use and adjusted if necessary. If it does not meet the specifications, the position of the generator and adjusting arm can be changed for adjustment. 4. Regular descaling: After the engine has been used for a certain period, scale will deposit in the water tank and radiator, affecting heat dissipation. Therefore, regular cleaning is necessary. The cleaning method involves adding enough cleaning solution to the cooling system, soaking for a period, then starting the engine to run at low to medium speed for a certain time before draining the cleaning solution while it is hot, followed by rinsing with clean water. 5. If the engine is found to be overheating, check promptly for water shortage. If there is a shortage, stop the engine and add sufficient coolant after it cools down. If the thermostat is not functioning properly, causing the engine to operate at excessively high or low temperatures, it should be repaired or replaced promptly.
