Radium Engineering Coolant Expansion Tank- Universal
Universal, pressurised coolant expansion tank designed for cooling systems where the radiator sits below the cylinder head. The two-piece 6061 aluminium body and an integrated swirl chamber purge trapped air, allowing the system to fill completely and maintain stable coolant temperatures.
Key features
-
CNC-machined, anodised aluminium body for high corrosion resistance.
-
750ml capacity in a compact footprint.
-
Inlet swirl chamber accelerates coolant de-aeration.
-
Internal channels linking upper and lower chambers enable self-bleeding.
-
ORB ports sealed with O-rings for leak-free, vibration-proof connections.
-
Pre-machined for a standard 32 mm Type-A pressure cap (optional).
Installation benefits
-
Complete fluid fill eliminates air pockets in the cooling circuit.
-
Lowers the risk of over-heating and cavitation in high-output engines.
-
Universal AN ports simplify integration in street, drift, and motorsport builds.
