Does Shen Feng ax7 electronic thermostat exhaust?
After replacing the antifreeze, first open the water tank cover or kettle cover to start the car, and the air will be discharged by the water pump. If the thermostat is damaged, the heat of the engine cannot be effectively dissipated, the water temperature of the engine rises, and the water temperature alarm lamp lights up. As a result, the engine water temperature is too low, the water temperature rises slowly, the fuel consumption increases, and the engine sounds abnormally.
Judgment method of thermostat:
1. Check after starting the engine. Open the filler cap of the cooling water tank and check whether there is water flow in the cooling water tank. If there is no water flow, it means that the thermostat is damaged or something is stuck between the main valve switches. .
You can judge by feeling the temperature of the upper and lower pipes with your hands. Start the engine first, and touch the upper and lower pipes after 3 minutes. If it is a good thermostat, the temperature of the upper tube and the lower tube is different, just as the upper tube is hot and the lower tube is cold. When the engine water temperature reaches 90℃, the upper and lower pipes are hot, which proves that the thermostat is good. If the temperature of the upper and lower pipes is straight after starting the engine, it means that the thermostat is broken;
3. Dismantle the thermostat from the car to do hot and cold water experiments, and observe whether the thermostat will open with the increase of water temperature and whether there is card sticking.
