RADIUM Coolant Expansion Tank, Universal

All Radium products are carefully planned with thorough R&D and designed in-house using the latest computer simulation and modeling techniques. Extensive testing and evaluation ensures the performance of Radium products exceed consumer expectations. For these reasons, top motorsports competitors and enthusiasts worldwide rely on Radium Engineering products.

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. The radiator cap must have a Type-A seal.

2x Bottom ports: -10AN ORB
1x Front port: -6AN ORB

The coolant expansion tank features two internal chambers. These chambers are NOT isolated from each other. There is cross-over passages at the top and bottom. This product is not a coolant overflow tank. Instead, it is designed to part of the pressurized coolant system.

The Radium Engineering coolant header tank also has an internal swirl feature, as shown below. Hot pressurized coolant from the cylinder head is sent into the vortex chamber’s inlet tangentially and accelerated to a high rate of rotation. This is to help aid in deaerating the system.
