BennettBuilt Aluminum coolant tank

  • Sale
  • Regular price $ 225.00

This Aluminum coolant reservoir is a direct replacement to the Rx8's OEM plastic coolant tank that can become brittle with age and is known to have coolant level sensor problems.

The tank is constructed from aluminum that is cnc cut for accuracy then tig welded for a clean strong weld. Billet aluminum barb fittings are then welded on to mate up with the OEM coolant hoses.

A more reliable coolant level sensor is used for longevity. This sensor is also serviceable meaning that it can be removed to be cleaned or replaced if ever needed which is a great improvement over the Rx8's sensor that cannot be removed, requiring complete replacement of the tank.



The kit includes: 

  • Custom Aluminum coolant tank
  • Custom coolant level sensor with wiring adapter
  • Lifetime warranty


Powder coating is available in many colors for an additional $30.
