Abstract: In apparatus for control of liquid coolant flow to and from an engine and radiator coolant system, comprising a closed tank to receive the coolant; a first line extending at the exterior of the tank, and also communicating with the tank interior, the first line connectible with the coolant system; ducting associated with the tank and having an inlet for connection to a source of compressed air, an outlet outside the tank, and having an aspiration side port between the inlet and outlet, the side port also connected to the tank interior; and a first valve for controlling compressed air flow through the ducting; whereby in one position of the valve compressed air flows into the tank via the side port to drive coolant from the tank interior via the first line and to the coolant system, and in another position of the valve compressed air flow through the ducting to the outlet acts to draw fluid into the tank from the engine coolant system via the first line, in response to suction communication to the tank interio

Abstract: An apparatus to supply liquid coolant, to and to transfer coolant from, an engine and radiator coolant system, comprising a supply tank having a coolant fill inlet, which is closable, and a coolant delivery outlet to deliver coolant via a hose to the engine and radiator coolant system; an air pressurization inlet to the tank to receive compressed air that forces coolant from the tank via the outlet; and structure responsive to a predetermined coolant flow from the tank for relieving pressurization of the tank, whereby coolant flow is then interrupted.

Abstract: The method of cleaning internal combustion engine fuel injector structure, valves and combustion chambers, and employing a canister containing a liquid mixture that includes engine fuel and injector cleaning solvent, the steps that include charging pressurized gas into the canister to a selected high-pressure level; communicating the interior of the canister with a passage extending to the injector structure and operating the engine, including a fuel pump to provide pressurized fuel discharge which is delivered to the passage; terminating operation of the fuel pump; continuing operation of the engine by allowing substantially continuous pressurized flow of the mixture in the canister to the injector structure, via the passage, and until the mixture in the canister depletes; and after pressure drops to a selected lower level, re-charging pressurized gas into the canister to a selected high-pressure level, and continuing the communication of the canister interior with the passage to flow more of the mixture to
