Expansion & Overflow Tank 20oz

Flex-a-lite® introduces a cooling system expansion and overflow tank that matches the engineering and appearance of the company's Flex-a-fit® radiators. Flex-a-lite's expansion and overflow tank brings several technical advantages to the cooling system. First, it is easy to verify that there is sufficient coolant in the system by visually inspecting the included clear hose that connects the tank to the radiator. Since it is unnecessary to remove the radiator cap, air will not be introduced into the cooling system, leading to overheating and also causing corrosion. The expansion/overflow tank is readily removed with a wing-nut mount, making it very easy to raise the tank during radiator filling. By using the Flex-a-lite expansion tank as the high-point in the cooling system, you can purge all of the air out of the cooling system. And, of course, it's made in the USA!
