OE Matching Quality car and truck expansion tank supply
The expansion tank is commonly used for the cooling system of internal combustion engines. It is installed above the radiator and mainly consists of a water tank, a water tank cap, a pressure relief valve and a sensor. Its main function is to maintain the normal operation of the cooling system by circulating coolant, regulating pressure, and accommodating coolant expansion, avoiding excessive pressure and coolant leakage, and ensuring that the engine operates at normal operating temperatures and is durable and stable.
