ABSTRACT:
A portable air-operated apparatus for cleaning, flushing, and filling a liquid cooling system of an internal combustion engine. The cooling system is cleaned by sequentially moving liquid in opposite directions in the cooling system. The apparatus also functions to pressure check the cooling system for leaks, to flush the cooling system of cleaning liquid and foreign matter, and filling the cooling system with new coolant liquid. The apparatus has an air-operated reciprocating piston pump assembly operable to agitate or sequentially move liquid in opposite directions and pump liquid into the cooling system. The pump assembly delivers the liquid to a manifold connected to an input hose coupled to the liquid cooling system. A control valve connected to the manifold is operable to direct an external source of liquid under pressure to the manifold or connect a reservoir carried by the apparatus to the manifold. The manifold has a check valve for controlling one-way forward flow of liquid from the pump to the input hose. A by-pass hose connects the control valve and manifold to by-pass the check valve to allow reverse flow of liquid in the input hose back to the pump assembly so that the pump assembly will effect a sequential forward and reverse flow of liquid in the cooling system. The control valve is operable to connect the reservoir to the manifold so that the cooling system can be filled by the operation of the pump assembly with liquid stored in the reservoir. A filter located in the reservoir filters liquid moved from the reservoir by the pump assembly to the cooling system.
