This universal overflow tank replaces the OEM plastic tank. The OEM tanks have a reputation of failing, and Radium now offers a bolt-in CNC machined aluminum replacement. This kit is designed to directly replace the OEM tank.  However, since it's a Universal option, mounting customization will need to be done.

The Radium Engineering coolant expansion tank is CNC machined from aluminum and consists of two halves that are bolted together. The parts are anodized for long life and an attractive finish. The volume of the Radium coolant tank is equivalent to the stock tank, so there is no loss in coolant.

The internal design features two chambers that have cross-over passages at the top and bottom. The Radium Engineering coolant header tank also has an internal swirl feature, which is to help aid in deaerating the system.

Note: This Kit Does Not Include Radium Cap.

Vehicle Applications:

  • Universal


  • Designed to completely replace the OEM tank
  • Uses OE lines and has OE tank capacity
  • CNC Billet Aluminum for nice appearance
  • OEM Radiator cap works
  • Internal swirl feature to help aid in deaerating the system
