Keep your cooling system under control. A radiator overflow tank is a simple upgrade that helps maintain the correct coolant level by capturing excess coolant as it expands and returning it to the radiator as the engine cools. The result is a more efficient cooling system and less chance of losing coolant during hard driving. Constructed from lightweight aluminium, this 1-litre overflow tank is ideal for performance vehicles, race cars, off-road builds, and custom engine bays. The polished finish also gives your engine bay a cleaner, more professional appearance.
