The car downpipe is a part of the cooling system, and its main function is to return the coolant after cooling the engine to the water tank. In the cooling system, the antifreeze first flows into the engine through the upper water pipe, absorbs the heat generated by the engine, and then returns to the water tank through the lower water pipe for cooling. Due to the low temperature of the coolant in the downpipe, its surface does not heat
Advantges
Ensure the normal operating temperature of the engine : The down pipe returns the cooled coolant to the water tank to ensure that the engine is always kept within the appropriate operating temperature range to avoid overheating or overheating, thus protecting the engine from damage
Improved cooling efficiency : Through efficient coolant circulation, downpipes help maintain stable engine operation and reduce performance degradation and potential failures caused by overheating
