Best Jeep Wrangler JK Coolant Overflow Tank

Your Jeep's coolant supply is part of its temperature control system. By circulating around the engine and through the radiator, it absorbs and releases excess heat as needed. As you probably remember from high school science classes, heat makes things expand and cold causes things to contract. Coolant is no different: It expands as its temperature increases. That excess coolant needs somewhere to go.

Your Jeep's coolant overflow tank provides the needed room for expanding coolant to flow. As the coolant circulates through the system, its pressure and temperature change. Thus, coolant can easily move between the tank and the system as needed. Morris 4x4 offers the best quality overflow tanks that meet or exceed OEM standards.
