Insufficient cooling medium: high-end cars need to be filled with antifreeze, water or distilled water all the year round: temporary substitution, water tank cover leaking.
Temperature controller damage: If you want to remove the temperature controller, plug the small circulation at this time, so as to ensure that the coolant is completely dispersed by the water tank. When installing a new thermostat, you should pay attention to the water hole. For example, Santana has no water hole. At this time, you should drill a hole with a 6mm drill. One function is used for marking; Another function is that when the car heats up, it will produce the temperature difference between the two sides of the thermostat, so that the thermostat can be opened accurately with the water temperature.
Precautionary measures for high water temperature of automobile
It should be noted that if the temperature is still too high after driving for a period of time, the cooling water volume will decrease after parking inspection, mostly because there are sand holes in the water jacket of the cylinder block, which will cause perforation and loss. If this fault occurs, it must be repaired. If the temperature of the automobile engine is too high, touch the temperature of the upper and lower pipes by hand to judge the fault.
If the temperature difference between the two water pipes is relatively large, it can be judged that the thermostat is not working. If you can't buy accessories on the way, you can remove the thermostat and bring it back to your unit or have a place to repair it. You should replace it immediately.
