Abstract
An automotive vehicle cooling system having a radiator connected to the engine coolant jacket for circulation of coolant, a pump delivering coolant from the radiator to the engine, a non-pressurized reservoir bottle communicating with the radiator and having a make-up line communicating with a venturi in a recirculating line around the pump directing coolant from the pump outlet to the pump inlet. The venturi allows make-up coolant to be added from the reservoir bottle at atmospheric pressure so that the bottle can be of a relatively lightweight gauge material.
