This product was designed to maximize engine compartment space, combining two reservoirs into a single component. Those running larger radiators or custom intercooler tubing can benefit from the rugged 1/8” thick, laser cut and formed aluminum construction, hand TIG welded for reliability. Mounts to OEM brackets and utilizes OEM fasteners, washer pump and caps, all of which remain secure even in extreme conditions. The Dual Tank setup is ideal for aftermarket radiators requiring the removal or relocation of the coolant expansion tank; plus it liberates additional space in the engine bay. All fittings and hose are DOT approved, ensuring optimum performance in the engine compartment. Coolant fittings are sold separately.
