Product Overview
This aftermarket replacement coolant overflow reservoir is a 2L polished aluminum expansion tank intended for catching and holding coolant that expands from a vehicle or equipment cooling system. An overflow or expansion reservoir provides space for heated coolant to expand and helps return coolant to the radiator as the system cools. The tank is supplied as a 2L capacity unit, so verify the tank volume, inlet size, mounting layout, and cap type against the original component before ordering.
