The Racer X Fabrication coolant tree for the Toyota MR2 was designed as a replacement for the OEM coolant tree that is often corroded from years of use. The coolant tree features 8AN ORB fittings and includes the hose barbs, which can also be blocked off with 8AN plugs should you choose to eliminate the heater lines. Finally the assembly retains the OEM coolant temperature sensor and the gauge sensor. It will eliminate the OEM cold start injector switch and VSV.


The Racer X coolant tree is comprised of 3 components completely CNC machined from 6061-T6 aluminum with o-ring seals on each mating component. The cylinder head flange eliminates the need for the OEM metal gasket, and can be directly bolted to the surface.
