Working principle
Automotive engine return water pipe is an important part of the cooling system. After the coolant absorbs heat inside the engine, it flows back to the radiator through the return pipe for cooling. The radiator dissipates the heat in the coolant to the air through the air flow, and the cooled coolant flows back to the engine through the return pipe, forming a circulation system. This process ensures that the engine is always kept within the appropriate operating temperature range
Maintenance method
Regularly check the coolant level : ensure that the coolant is within the specified range, and should be added in time when insufficient.
Check the quality of the coolant : regularly check the pH, freezing point and boiling point of the coolant, and replace the coolant if necessary
