Radium Engineering Coolant Tank Kit - Can-Am Maverick X3 / Defender / Sea-Doo RXT

This replaces the factory plastic coolant tank with a CNC machined 6061 billet aluminum header tank holding 1240 mL, about 240 mL more than the OEM part, so there is more coolant volume and one less plastic component to go brittle with heat. It mounts in the original location on supplied brackets, carries a 4.6 in sight window so the level reads at a glance, and uses AN ORB ports adapted to barbed fittings at the top, bottom and overpressure purge. Brackets, fittings, overflow hose, clamps and hardware are in the box. The pressure cap is sold separately.
