Brand: Optimum Balance Products (OBP)

This lightweight aluminum coolant header tank (expansion or fill tank) has barbed inlet and outlet fittings for use with rubber coolant hose. The bottom fitting accepts 3/4" ID hose, and the top inlet accepts 3/8" ID hose. The vent outlet accepts 5/16" hose. The tank has built-in side mounting brackets and accepts a standard radiator cap (sold separately).

A header tank is recommended for racing applications where the top of the radiator is mounted lower than the top of the engine. Mounting the tank higher than the engine insures a complete fill and provides an air space for expansion. Accepts any standard automotive radiator cap such as our Stant Radiator Caps, sold separately.
