Solutions to high water temperature:
1. Check whether the water tank is leaking. Open the water tank and see if the water level is below MIN. If the water level is very low, it is likely to be leaking. Add water, open the exhaust screw near the engine to exhaust, and check for water leaks. Air in the water tank will also cause the water temperature to be high. Water leakage usually occurs when the car is cold, so check it after the car is hot and cool down. Pay attention to see if there is any leakage in the heater water pipe joint leading to the driver's compartment. If there is a large amount of water leakage, look at the ground under the car when you get up in the morning. knew. If there is no leakage point, but the water gradually drops below the lowest point after a week or half a month after filling it with water, then there is another possibility that the cylinder gasket is stuck and the water has seeped into the engine and been consumed. Open the oil filler port to see if there are foam and bubbles, see if there is oil in the water tank cap, and see if there are white water droplets on the oil dipstick. If there is, water has seeped in. The cylinder gasket needs to be replaced.
2. Replace the water temperature sensor. If the pot is not turned on and the water temperature is only high, it may be caused by an inaccurate water temperature sensor. Replace the water temperature sensor.
3. Replace the thermostat. The thermostat cannot be opened, causing hot and cold water to not circulate. After the water temperature reaches 90 degrees, open the hood and touch the water pipe near the engine to get hot (be careful to scald your hands). If the water tank is not hot, it means that the water is not circulating. It should be hot on both sides. Otherwise, the thermostat needs to be replaced.
4. Replace the water pump. The water pump is the most expensive, so it should be replaced last. Over time, the fan blades of the water pump may become broken, fall off, or become clogged. I once saw with my own eyes that there were a lot of rubber-like things stuck in the water pump of my car. The water pump was not working well and could not circulate the water, causing the water temperature to rise rapidly. rise. This will require replacing the water pump.
