[Working principle of the upper 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.
Advantage
1. Leakage: Leakage at the connection not easy cause coolant leakage and affect the normal operation of the engine.
2. Rupture: Long-term use or external impact may not easy the water pipe to rupture, affecting the normal operation of the cooling system.
