1. Replace water temperature sensor. Not boiling the pot just means that the water temperature is high, or it may be caused by the inaccurate water temperature sensor.
2. Replace the thermostat. When the thermostat is not turned on, cold water and hot water will not circulate. When the water temperature reaches 90 degrees, open the engine compartment cover and touch the water pipe near the engine. If the water tank is not hot, it means that the water is not circulating. Both sides are hot, otherwise the thermostat will be replaced.
3. Change the water pump. The water pump is the most expensive and should be replaced last. After driving for a long time, the fan blades of the water pump are broken, dropped or blocked, and the water pump does not work well, which can not let the water circulate, resulting in a rapid increase in water temperature. This requires replacing the water pump.
How to deal with the high water temperature when the engine is running;
When the engine is running, once the water temperature is too high, observe whether the radiator water inlet faces outwards when the engine is running. If the water inlet of the radiator faces outwards, the easiest way is to make the beverage can into a shape similar to the inner diameter of the water inlet and cool it to the water inlet of the radiator.
If the temperature is too high or the temperature indicator is flashing all the time, stop to check whether the cooling water in the water tank is normal and whether there is any leakage in the water tank and water pipe. If no abnormality is found in the inspection, you can replenish cooling water and continue driving. If the temperature is still too high after driving for a certain distance, the cooling water will decrease after parking inspection, which is mostly due to sand holes or perforations in the water jacket of the cylinder block. After this fault is found, it should be repaired.
