Mazda RX-8 Aluminium Coolant Expansion Tank (3 versions)
Quality Aluminium Coolant Expansion Tank.
As an RX-8 specialist we know that the standard OEM plastic Coolant Expansion Tank over time becomes prone to failure. Should the Tank leak the engine will quickly over-heat, causing increased pressure and hence more coolant loss. Rotary Engines with no coolant are potential “Time Bombs”, rapid overheating and potential engine failure.Pettit State “Pettit’s Aluminium Coolant Tanks will never fail”

AST Spec. A Kit.
Our most comprehensive kit lets you setup a closed cooling system by combining our recovery reservoir with our aluminium tank. In this configuration the aluminium tank works as an Air Separator Tank (AST), reducing entrained air in the system. This kit also features a low level sensor to signal the RX8 dash warning light for low coolant.
- AST Spec. B Kit.
This kit lets you setup a closed system by combining our recovery reservoir with our aluminium tank. In this configuration our aluminium tank works as an Air Separator Tank (AST), reducing entrained air in the system.
Spec. C Kit.
In its simplest configuration, our aluminium coolant tank can be used as an OEM replacement for the original plastic expansion tank, only much-stronger!
Superb Weld Quality
