The Nightrun Garage MK4 Toyota Supra coolant overflow tank is now available! We designed and constructed this tank out of 6061 T6 schedule 40 aluminum pipe for maximum strength. The tank is mounted on the USDM driver's side near the stock battery location and provides around 16 FL oz of coolant overflow capacity. The battery must be remotely mounted for this overflow tank to be mounted correctly and is available in a raw aluminum finish, black wrinkle powder coat, or satin black powder coat. We use a Vibrant Performance thread-on cap and the rest of the tank is fabricated in house. This tank can be used on other cars but is designed to work best on the Mk4 Supra.
Please allow a maximum 3-4 weeks for fabrication as these are handmade.
