Water Header Tank, Horizontal, 8" L x 4" Dia, without Cap

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 inlet fitting accepts 3/4" ID hose, and the top outlet accepts 3/8" ID hose. The vent outlet accepts 5/16" hose. The tank has a built-in mounting bracket on the back. Accepts any standard automotive radiator cap such as our Stant Radiator Caps, sold separately. Natural aluminum finish looks great as-is, or you can sand and polish it for a mirror finish.

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.
