Radium Coolant Expansion & Swirl Pot

Radium Coolant Expansion & Swirl Pot

If you are building a custom cooling setup and want the best possible soltuion to remove air pockets that can create hot spots in your engines head, which in turn can blow a head gasket or lead to warping= this is it! We have run this kit on our E46 Time-Attack car for years with great success.

Coolant expansion tanks are necessary for proper air bleeding in applications that utilize a low mounted radiator (such as a V-Mount) or rear mounted radiator. However, expansion tanks are also valuable if integrated in a common radiator setup. To allow heat expansion, traditional coolant systems require air to be present in the top portion of the radiator during low temperatures. An coolant expansion tank permits the radiator to be 100% filled with coolant in all conditions. 

 

The Radium Coolant Expansion Tank holds 750mL. It is a 2-piece design constructed of CNC billet 6061 aluminum. The two halves (shown below) are bolted together along with a CNC billet aluminum radiator neck which accepts a standard 32mm "Mini" style pressure cap. 

 

Kit includes:

  • Billet Aluminum Coolant Tank
  • Anodized Aluminum Mounting Bracket 
  • 6AN Male Adapter Fittings (x3)
  • 6AN 90 degree Push-Lok Hose Ends (x3)
  • Nickel-Plated Fittings and Sight Tube 
  • Billet Aluminum 32mm Pressure Cap Receiver 
  • Aluminum Pressure Bleed, 1/4" Barb

 

The optional Radium Engineering pressure caps (sold separately) allow the user to select a range of pressure. The purpose of a high pressure cap is to increase the boiling point in the cooling system providing improved cooling efficiency. Each cap is manufactured from stainless steel with a race proven high pressure valve. This is something to consider when tracking the vehicle in extreme conditions.
