ABSTRACT:
An automotive air conditioning flushing apparatus having a solvent tank separated from a catch basin by means of a pressure tank and multiple position sequencing valve. A handle of the valve rotates through positions which sequentially direct solvent into the pressure tank by gravity feed, then pressurize the solvent from a remote pressure source and cause pressurized fluid to be delivered into an automotive cooling system, then release pressure and dispose of excess cleaning solvent. Lastly, the handle may be rotated to an off position. System components are stacked one above the other on an upright wheeled frame so that the entire apparatus may be easily moved about in an automotive service facility.
