The reasons for the thermostat not opening: The water temperature is not high enough; The water channel is blocked; The radiator is frozen. Here are some introductions about the thermostat: 1. Water with excessively high temperature and pressure cannot be pressed into the water tank by opening the radiator cap, which may cause damage to the water jacket of the small circulation system. 2. The main type of thermostat used is the wax thermostat. When the cooling temperature is below the specified value, the refined paraffin in the temperature sensing body of the thermostat is in a solid state, and the thermostat valve closes the channel between the engine and the radiator under the action of the spring. The coolant returns to the engine through the water pump, performing a small circulation within the engine.
