Are you certain you don't have a heater water valve?

The text & illustration sections of the parts catalog shows one for a Ranger 3.0, w/o A/C mounted on the passenger side of the engine.

The valve resembles the letter Z with a port top & bottom, two more in the center. It looks more like a manifold than it does a valve.
