1, the water tank is dirty and the water temperature is high, so it is necessary to clean the water tank and replace the antifreeze. After replacing antifreeze, be sure to exhaust, otherwise the water temperature will be high.
2. There is something wrong with the cooling fan of the water tank. Clean the coolant in the water tank, add antifreeze after cleaning, and check the cooling fan until it works normally.
3. Water leakage in water pipe joints, tees, water tanks, water plugs, water storage kettle covers and other parts leads to insufficient antifreeze and high water temperature. Solution: Find out the leak and fix it, and add antifreeze.
4. The air is not exhausted when the antifreeze is replaced due to car repair or other reasons, resulting in the water temperature rising and falling during driving. The solution is to exhaust again and add antifreeze.
5. The fault phenomenon of high water temperature in operation indicates that the water thermometer indicates high or the water storage kettle overflows. Severe high temperature will cause the water pipe to break or accelerate weakly, and even cause the engine cylinder gasket or cylinder pulling.
