The Radium Engineering billet aluminum coolant tank replaces the plastic OEM tank located at the front of the engine bay in the R35 GT-R. The full functionality of the cooling system is retained in a more compact and robust package.
The coolant tank is CNC machined from 6061 aluminum and is anodized and laser engraved. It installs on a custom-designed mounting bracket for the R35 that utilizes factory mounting points, so no drilling or permanent modifications are required.
The compact size frees up room for aftermarket modifications and makes the engine easier to access for servicing.
Unlike the OEM plastic coolant tank, the aluminum construction of the Radium coolant tank is not prone to fatigue cracking after repeated high heat loading. Furthermore, the Radium coolant tank can be disassembled and serviced at any time. The aluminum coolant tank also features an integrated swirl pot so that incoming hot water has a chance aerate. All connections into the coolant tank are -AN ORB (O-ring) for the best reliability.
