The Megan Racing Radiator Breather Tank is designed to be a more efficient way to fill and maintain the cooling system, and ensure any air in the system can escape. The Megan Racing Radiator Breather Tank works by allowing you to connect popular coolant passages such as the lower radiator hose, cylinder head, expansion tank or radiator neck in key spots together, to allow your system to vent, so no air bubbles will get trapped in the system, causing coolant to not flow optimally, and cause you to overheat.

One of the most crucial aspects to maintaining your engine, and your car's performance, is ensuring your engine can run cool, and the cooling system can operate as intended. Especially on modified vehicles, the cooling system requires extra attention. We recommend the Megan Racing Radiator Breather Tank, and recommend this for any stock or modified vehicle.
