Radium Engineering Coolant Tank Kit - Nissan GT-R (R35)
The Radium Engineering Coolant Tank Kit replaces the factory plastic coolant expansion tank on the Nissan GT-R (R35). Plastic tanks have a reputation for failing under constant, intense heat cycling, so Radium's two-piece tank is CNC machined from aluminium and anodised for longevity, improving heat transfer and standing up to race use.

The kit is a direct replacement with no permanent modifications: a purpose-designed bracket bolts to existing threaded holes and adapter fittings connect to the factory coolant lines. System function is unchanged, but the smaller tank frees up engine bay space for other modifications and servicing. Internally, two chambers with crossover passages top and bottom and a swirl feature help de-aerate the coolant.
Note: The OEM 1.37 bar Nissan pressure cap can be reused, or a Radium Type-A cap in various pressure ratings can be fitted instead (sold separately). Installation by a professional is recommended.
