Abstract
An apparatus for adding coolant to a cooling system of a motor vehicle includes a cap with a resilient sleeve that expands against the inside wall of a radiator filler neck to provide an air-tight connection. A valve attached to the cap controls the flow of air and coolant through the cap. A gauge on the cap indicates the pressure inside the radiator. A venturi assembly connected to the valve provides a source of vacuum for evacuating air from the cooling system. Thereafter, coolant is drawn through the cap by the vacuum created in the system.
