Radium Engineering Universal Coolant Tank, 1240mL – 20-2270

Radium Engineering Universal Coolant Tank, 1240mL – 20-2270

Application: Universal – pressurised coolant systems
Part Type: Coolant expansion tank, 1240mL
Part Number: 20-2270

Coolant expansion tanks are necessary for proper air bleeding in applications with a rear-mounted radiator or a low-mounted radiator such as a V-Mount, but they are also valuable in a conventional radiator setup. A traditional cooling system needs air in the top of the radiator at low temperatures to allow for heat expansion; an expansion tank lets the radiator stay 100% filled with coolant in all conditions.

The Radium Engineering Universal Coolant Tank holds 1240mL and is a multi-piece design CNC machined from billet 6061 aluminium. It has two internal chambers that are not isolated from each other, with cross-over passages at the top and bottom. A pressure cap is not included – the billet receiver accepts Type-A "radiator" caps.

Key Features

• 1240mL Capacity: Multi-piece CNC billet 6061 aluminium construction
• Type-A Cap Receiver: Accepts Type-A radiator pressure caps (sold separately)
