The car heater tank is introduced as follows:
The cooling system of the engine is blocked by air, which leads to the abnormal operation of the cooling circulation system of the automobile and the problem that the warm air is not hot. If the inlet pipe of the warm air small water tank is hot and the outlet pipe is cold, it means that the small water tank is blocked and needs to be replaced.
The water flow in the water tank is reduced due to the damage or loss of the water pump impeller of the vehicle, and the warm air is not hot, so it is necessary to replace the water pump impeller. It is also possible that the thermostat has been on or opened too early, which leads to the early circulation of the cooling system and the low temperature outside the car.
