Product Description

The Radium Engineering 20-0557 Coolant Tank Kit provides a robust upgrade to the OEM plastic coolant expansion tank in the Nissan R35 GT-R (VR38DETT engine) from 2009 through 2019. Precisely CNC-machined from billet aluminum and finished with corrosion-resistant anodizing, this tank resists heat cycling and the deterioration common with plastic reservoirs, making it suitable for both street and motorsport applications.

Installation is straightforward with a direct-fit bracket that uses existing OEM threaded holes, and adapter fittings allow seamless connection with the factory coolant lines without permanent modifications. The internal swirl and dual-chamber design helps remove entrained air from the cooling system, improving overall coolant circulation efficiency. The OEM coolant tank pressure cap can be reused, or replaced with optional Radium caps for custom cooling setups.
