Radium Engineering Coolant Expansion Tank Firewall Mount

Perfect Fit for Your Lotus Elise & Exige (2006-2011)

If you're looking to enhance your Lotus with a reliable coolant solution, the Radium remote-mounted coolant header tank is just what you need. This tank is ideal for custom applications like engine swaps or turbocharger kits, especially when the original expansion tank isn't in the best spot anymore.

Quality Design You Can Trust

The main tank features a robust 2-piece design crafted from CNC 6061 billet aluminum, ensuring both durability and performance. The two halves are securely bolted together, and it comes with a CNC billet aluminum cap receiver that fits any standard 32mm "Type-A" style pressure cap.

Why You Need a Coolant Header Tank

For setups that use a low-mounted radiator, such as a V-Mount, having a coolant header tank is essential for effective air bleeding. This tank is designed to handle those needs seamlessly.

Innovative Swirl Feature

What sets the Radium Engineering tank apart is its internal swirl feature. Hot pressurized coolant from the cylinder head enters the vortex chamber's inlet tangentially, creating a high rate of rotation. This clever design helps to efficiently deaerate the system—a classic hot rod technique that works wonders.

Included Components

  • Billet Aluminum Coolant Tank (Anodized Black)
  • Aluminum 6AN Male Adapter Fittings (Anodized Black)
  • Nickel Plated Sight Tube Fittings
  • Billet Aluminum 32mm Pressure Cap Receiver
  • Billet Aluminum Pressure Bleed Nipple
  • Laser Cut Aluminum Firewall Mounting Bracket (Powder Coated Black)
  • Aluminum and Stainless Steel Mounting Hardware

Optional Upgrades

Consider the optional Radium pressure caps (sold separately) for a range of pressure options. A high-pressure cap can boost the boiling point in your cooling system, enhancing cooling efficiency—especially useful for those intense track days. Each cap is made from stainless steel and features a race-proven high-pressure valve, which is a great addition for extreme conditions.

The OEM Lotus pressure cap operates at 1.1 Bar.

Compatibility

  • Lotus Elise (2006-2011)
  • Lotus Exige (2006-2011)

Upgrade your Lotus with confidence, knowing that the Radium Engineering Coolant Expansion Tank is designed to fit perfectly and perform exceptionally.
