Radiator overflow tanks, including those by OER Authorized, serve the purpose of collecting and temporarily storing excess coolant from the radiator that expands due to engine heat. This prevents coolant from being expelled onto the ground and allows it to be drawn back into the cooling system as the engine cools down. Essentially, the overflow tank acts as a reservoir and safety valve for the cooling system. These OER Authorized overflow bottles are manufactured to factory dimensions of the original for the vehicle intended and features correct mounting points for installation. Correct OE-style cap is also included. Order the model for your application.
