Ruixing m80 heater is not hot? Are there any other switches?

The thermostat is faulty and there are no other switches. The user can replace the thermostat.

The thermostat is always open or the thermostat is opened too early, causing the cooling system to undergo a large cycle prematurely. When the outside temperature is very low, especially when the car is running, the cold wind quickly cools the antifreeze. , the engine water temperature cannot come up, and the heater air will not heat up.

The impeller of the water pump is damaged or lost, causing insufficient flow through the small warm air water tank and preventing heat from coming in. There is an air blockage in the engine cooling system. The air blockage causes poor circulation in the cooling system, causing the water temperature to be high and the warm air to be tepid. If there is always air in the cooling system, it is likely that the head gasket is damaged and air is flowing into the cooling system.

Notes:

1. In the early stages of engine operation, the coolant temperature rises rapidly; when the coolant temperature gauge indicates 80°C, If the temperature rise rate slows down, the thermostat is working normally.

2. When the coolant temperature gauge indicates 70-80°C, open the radiator cover and radiator waterproof switch, and feel the coolant temperature with your hands. If it is hot, it means the thermostat is working normally; if the heat dissipation The coolant temperature at the water inlet of the radiator is low, and there is no or very little coolant flowing out from the water inlet pipe of the radiator upper water chamber, which means that the main valve of the thermostat cannot be opened.

3. If the coolant in the radiator is calm, it means that the thermostat is working normally. Otherwise, it means that the thermostat is not working properly. When the coolant temperature gauge indicates below 70°C, if there is coolant flowing in the radiator inlet pipe and the coolant is warm, it means that the main valve of the thermostat is not closed tightly, causing the coolant to circulate prematurely.
