The Racer X Fabrication coolant over flow for the 91-95 Toyota MR2 was designed to replace the OEM coolant overflow. The Racer X coolant overflow is CNC machined from 6061-T6 aluminum and the top features a removable cap for simple filling. The body of the coolant overflow uses 1/4” NPT swivel fittings and a clear tube for an easy visual check of the coolant level. The bottom includes an 1/8” NPT plug, but could be replaced for different routing configuration. The entire aluminum assembly is anodized black and the Racer X logo is etched on the cap and coolant overflow body, the logo uses the same placement as our catch can so side by side mounting looks similar.
