ABSTRACT:
An internal combustion engine coolant extractor/injector with coupling comprises a tank assembly, an air pressure control assembly and a hose assembly. The air pressure control assembly creates a vacuum in the tank assembly by using the venturi effect. The air pressure control assembly does this by connecting to a compressed air hose. The air from the air hose flows through a venturi chamber creating a vacuum. The vacuum forces air out of the tank, creating a vacuum in the tank. The vacuum is maintained in the tank by means of a valve.
A transfer hose is also connected to the tank. The transfer hose is inserted into an automobile radiator; in the alternative, the transfer hose is connected to an automobile radiator by means of a coupling. The valve is then opened. The vacuum in the tank pulls coolant out of the radiator through the transfer hose and into the tank.
Coolant is injected or reinjected into the radiator by increasing the air pressure inside of the tank. A Schraeder valve on the tank is connected to a compressed air hose. Air flows into the tank through the Schraeder valve until the inside of the tank reaches the necessary air pressure. When the desired air pressure level is reached, as determined by an air pressure gauge connected to the tank, the compressed air hose is removed from the Schraeder valve which maintains this pressure. The open end of the transfer hose is then inserted into an automobile radiator or connected to it by means of the coupling, and the valve is opened. The increased pressure inside of the tank forces coolant out of the tank, through the transfer hose, and into the radiator.
