Function of small water tank
The function of the car small water tank is to store antifreeze. The blockage of the small water tank of the automobile will lead to the abnormal cooling of the vehicle, which will lead to the leakage of the water tank, the failure of the vehicle cooling system and the boiling of the water tank or the engine. The damaged small water tank needs to be repaired or replaced in time.
When the engine temperature is high, the liquid expands, and a part of antifreeze flows into the auxiliary water tank through the small water tank. When the temperature drops and the cooling system pressure is negative, the system sucks antifreeze from the auxiliary water tank into the cooling system through the small water tank. Small water tank is an important part of automobile cooling system, which plays a vital role in vehicle cooling.
