Description

Radium Coolant Expansion Tank OEM location - Elise/Exige 06-11 (2ZZ-GE)

Application: Lotus S2 Elise / Exige - Toyota 2ZZ-GE (naturally aspirated and supercharged)
Part Type: Billet coolant expansion swirl tank kit, OEM location
Part Number: 20-0270-01

The Radium OEM Location Coolant Tank Kit replaces the Denso plastic expansion tank fitted to Lotus 2ZZ-GE Elise and Exige models, which has failed in some cases. The billet aluminium tank features an internal swirl chamber that spins pressurised coolant in a vortex to help de-aerate the system.

The kit uses two separate mounts and factory threaded holes, so no drilling is required, and Radium notes an average mechanic can install it with the rear clam in place. Factory hoses are adapted to 6AN with the included fittings.

Key Features

OEM Location: Replaces the factory plastic expansion tank
Swirl Deaeration: Internal vortex chamber removes entrained air
Billet Construction: Two-piece billet aluminium tank with CNC cap receiver
No Drilling: Uses factory threaded holes and two separate mounts
6AN Plumbing: 6AN male adapters for a positive seal - no tapered pipe threads
Sight Tube: Nickel-plated sight tube fittings

Billet aluminium coolant tank, black anodised
Nickel-plated sight tube fittings
Aluminium 6AN male adapter fittings, black anodised
Aluminium 6AN hose ends, black anodised
Laser-cut aluminium tank bracket, black powder coated

Optional Parts

Radium Engineering Radiator Cap Type A Black (18-0076-A11 / A13 / A15) - 32mm Type-A pressure cap in 1.1, 1.3 or 1.5 bar
