Coolant expansion tanks, also called overflow reservoirs or surge tanks, manage the volume change that occurs as engine coolant heats up and expands during normal operation, storing the overflow when the system pressurizes and returning it to the radiator as the engine cools. Factory plastic expansion tanks are a common failure point on many performance and modified vehicles because the repeated pressure cycling and elevated temperatures of a high-output engine cause the OEM plastic to crack, weep, or lose pressure cap integrity faster than a stock application would. Upgraded aluminum, carbon fiber, and high-density polyethylene expansion tanks from Mishimoto, Cordes Performance, and Billet Technology improve cooling system reliability by resisting heat deformation, maintaining correct pressure cap seating, and providing a larger fluid reserve that extends the thermal management capacity of the system under sustained hard driving. Vehicles running modified cooling systems, larger ra...
