ABSTRACT OF THE DISCLOSURE: 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 appara- tus also functions to pressure check the cooling system for leaks, to flush the cooling system of cleaning liquid and for- eign 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 con- trol 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 reser- voir 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.
