A radiator fluid exchanging apparatus for servicing an engine coolant system having a radiator with an influent port and an effluent port, said apparatus comprising:
- a first fluid supply tank for supplying a supply fluid and having a multi-directional supply coupling defining first and second supply outlets in communication with a suction inlet disposed within said first fluid supply tank;
- a pressure vessel for collecting a waste fluid and including a waste fluid coupling in communication with an interior of said pressure vessel and defining a waste fluid collection inlet and a waste fluid exhaust;
- a pressure generator coupled to said pressure vessel and being operable to selectively direct said waste fluid into said pressure vessel through said waste fluid collection inlet under a negative pressure;
- a remove and fill control manifold coupled to said pressure vessel and said first fluid supply tank and including a remove and replacement port for coupling to said effluent radiator port, said remove and fill control manifold including a waste fluid collection pathway for routing said waste fluid entering said remove and fill control manifold from said effluent radiator port, when coupled thereto, to said waste fluid collection inlet, and further defining a fluid replacement pathway for routing said supply fluid entering said remove and fill control manifold from one of said supply outlets of said first fluid supply tank to said effluent port of said radiator, when coupled thereto, said remove and fill control manifold being selectively operable to direct said waste fluid through said waste fluid collection pathway or said supply fluid through said fluid replacement pathway under said negative pressure;
- a flush control manifold coupled to said first fluid supply tank and said pressure vessel, said flush control manifold including a fluid supply pathway between one of said supply outlets and a pump exhaust outlet and further defining a drain pathway for routing said collected waste fluid exiting said waste fluid exhaust to said pump exhaust outlet, said flush control manifold being selectively operable to route said supply fluid through said fluid supply pathway or said collected waste fluid through said drain pathway;
- and
- a pump including a fluid receiving inlet coupled to said pump exhaust outlet of said flush control manifold and further including a fluid directing outlet for coupling to said influent port of said radiator, said pump being selectively operable to direct said supply fluid from said first fluid supply tank into said fluid receiving inlet and out of said fluid directing outlet when said flush control manifold is selectively positioned to open said fluid supply pathway.
