OE Matching Quality car and truck expansion tank supply

Short Description:

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.

The main principle is that when the mixture of coolant, antifreeze, and air in the system expand with increasing temperature and pressure,it enters the water tank, playing a constant pressure role and protecting the hose from bursting. The expansion tank is filled with water in advance, and when the water is insufficient, the expansion tank also serves to replenish water for the engine cooling system.
