Radium Coolant Tank Kit | 2009-2019 Nissan R35 GT-R (20-0557)

Godzilla's cooling system deserves an expansion tank machined to the same standard as the rest of the car.

The Radium Engineering Coolant Tank Kit for the Nissan R35 GT-R replaces the factory plastic expansion tank on the 2009-2019 VR38DETT platform: a TIG welded aluminum tank with chassis-specific mounting, ending the aging-plastic failure risk while adding the pressure-cap flexibility and hardware quality a tuned GT-R runs at. Bolt-in installation in the factory location.

What You'll Feel

• The plastic-tank failure risk retired from a car that generates serious heat at pace
• Coolant level visible and serviceable through purpose-built hardware
• An engine bay detail matching the VR38's billet-heavy aftermarket
• Pressure cap options open via Radium's cap range (sold separately)

Features

• Aluminum coolant expansion tank kit for the 2009-2019 Nissan R35 GT-R
• TIG welded construction with chassis-specific mounting
• Bolt-in installation in the factory tank location
• Compatible with Radium pressure caps (sold separately)

The Details

Factory expansion tanks age on a schedule set by heat cycles, and the GT-R's twin-turbo V6 writes an aggressive schedule, with track use compounding it; the aluminum replacement removes the failure mode rather than deferring it. Radium's coolant tank architecture keeps the factory hose interfaces serviceable and the cap selectable, letting owners match relief pressure to their cooling system's needs through the optional cap range. Installation is a straightforward swap in the factory position, coolant drained and refilled per Nissan's bleed procedure, and the bay gains a component that matches the car.

Kit Includes

• 1x TIG welded aluminum coolant expansion tank
• Chassis-specific mounting and hardware
• Pressure cap sold separately
