OVERVIEW

Stock plastic coolant tanks are prone to failure and can leave a vehicle stranded.
This Radium Coolant Expansion Tank holds 1240mL and installs in the exact same location as the OEM coolant tank. It is a multi-piece design constructed of CNC billet 6061 aluminum. The tank is assembled with stainless steel fasteners and O-ring seals. It features a clear sight window to monitor coolant level. Custom fittings are included for easy connection to all factory hoses. Like the OEM tank, this product features two internal chambers that are NOT isolated from each other. There are cross-over passages at the top and bottom.

A pressure cap is not included with the coolant tank kit. Either re-use the factory cap, or select a Radium "Type-A" pressure cap from this link.

PRESSURE CAPS

The optional Radium Engineering pressure caps (sold separately) allow the user to select a range of pressure. NOTE: The OEM pressure cap is 1.1bar. The purpose of a high pressure cap is to increase the boiling point in the cooling system providing improved cooling efficiency. Each cap is manufactured from stainless steel with a high pressure valve. This is something to consider when using the vehicle in extreme conditions. For more information, go HERE.

Radium Pressure Cap - 1.1 Bar (110 kPA, 15.6 psi)
Radium Pressure Cap - 1.3 Bar (130 kPA, 18.9 psi)
Radium Pressure Cap - 1.5 Bar (150 kPA, 21.8 psi)

SPECS & FEATURES

The Radium Engineering coolant tank is 240mL larger than the OEM coolant tank.

Threaded Port Information:

The 6AN ORB (9/16"-18) top port is the inlet for incoming hot water and is an air bleed for the system. The 1/4" (6mm) low profile barbed fitting connects directly to the OEM hose.
The 10AN ORB (7/8"-14) bottom port (opposite the inlet port) is the drain back outlet. The 3/4" (19mm) barbed fitting connects directly to the OEM hose.
The other 10AN ORB (7/8"-14) bottom port (under the inlet port) is not used. A plug is provided.
The 1/4" (6mm) barbed fitting on the receiver cap is for over pressure purging. The clear OEM hose or the new hose can be used.
