Chevrolet Express Coolant Reservoir

The Chevrolet Express Coolant Reservoir protects the engine of the van by storing excess antifreeze and feeding it back to the engine when the temperature drops. This prevents leaks in the cooling system and keeps air from entering the cooling passages. The radiator is joined to this plastic tank via a hose. Due to pressure rise, heated coolant flows into the tank. More coolant is drawn back from the tank as the system cools down. In this way, fluid levels remain constant and metal components are kept free of corrosion. Over the years, the Chevrolet Express models have been designed with two main styles of cooling system. These are the overflow type and the expansion type. The overflow version is a non-pressurized Coolant Reservoir with a simple plastic lid. The pressure cap is on the radiator, so hot coolant spills into the tank and then is siphoned back when the temperature drops and a vacuum forms. This expansion layout employs a reinforced pressurized Coolant Reservoir, mounted high above the radiator and wearing the metal pressure cap itself, providing extra internal space for liquid expansion. Rather than forcing coolant out, it vents air when pressure rises and then allows outside air back in as the engine cools to avoid aeration. The Coolant Reservoir has clear level markings which allow the driver to check fluid with the engine cold. It protects every Chevrolet Express trip from overheating, regardless of design fitted. The Coolant Reservoir's design ensures optimal performance and longevity.

Each OEM Chevrolet Express Coolant Reservoir we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
