ABSTRACT:
A coolant reservoir is physically spaced apart from and elevated above the lower surface of an engine cooling system radiator. A coolant transfer conduit permits excess coolant to be transferred from the radiator into the coolant reservoir. A first one way check valve prevents fluid flow from the radiator into the reservoir unless the pressure within the cooling system exceeds a predetermined maximum value. A coolant refill conduit provides a coolant flow path between the reservoir and the radiator. A second one way check valve is coupled in series with the coolant refill conduit and permits coolant to flow from the reservoir into the radiator when the engine cooling system pressure drops below a predetermined value.
