This radiator comes with silicone hoses available in a choice of black, blue or red colours. Please select your desired colour from the drop down menu when ordering.

When fitting an all aluminium radiator, only distilled water together with genuine coolant or a performance waterless coolant should be used. Tap water is not suitable as it contains charged particles that can react with the aluminium over time.
