Patent ID: 6877531

Claim:
An apparatus for servicing an automobile fluid containing subsystem having a fluid reservoir with a subsystem pump and an inlet port and an outlet port, said apparatus comprising: a manifold block including a network of interconnecting channels defining a first manifold port being adaptable to couple with said inlet port, a second manifold port being adaptable to couple with said outlet port, a fresh fluid manifold port, a used fluid manifold port, and a fluid transfer circuit therebetween; a first valve removably secured to said manifold block and having a valve inlet port in communication with said second manifold port and a valve outlet port in communication with said first manifold port and said used fluid manifold port, said first valve being selectively operable to place said second manifold port in communication with either said first manifold port or said used fluid manifold port; a fresh fluid source coupled to said fresh fluid manifold port; a common pump interposed between said fluid manifold ports and said first manifold port for pumping a fluid from either of said fluid manifold ports to said first manifold port; a second valve removably secured to said manifold block and having a valve outlet port in communication with said common pump and a valve inlet port in communication with said used fluid manifold port and said fresh fluid manifold port, said second valve being selectively operable to place said used fluid manifold port or said fresh fluid manifold port in communication with said first manifold port; and whereby, upon coupling said first manifold port to said inlet port and said second manifold port to said outlet port, said subsystem pump may be activated and said common pump may be selectively operated to direct at least one fluid through said fluid transfer circuit as determined by the selective operation of at least one of said valves.
