Expansion Tank

An expansion tank, or coolant reservoir, holds extra coolant that expands from the engine as it heats and returns it as it cools. We carry 31 expansion tanks from $21 to $190 for 1963-2025 vehicles, from Dorman, AC Delco and others, with fits for the Chevrolet Camaro, Corvette and Silverado 2500 HD, Ford F150 and Jeep Wrangler.
