[Working principle of the lower water pipe connecting the car radiator]:
The upper water pipe of the car radiator connects the engine and the water tank, and circulates the coolant to the engine through the water pump, absorbs the heat generated by the engine, and maintains the normal operating temperature of the engine.
【Installation tips】:
