If it is at the rear of the water pump, behind the timing cover, it is the inlet housing(pipe). A little more to describe what I think you are talking about, is one of the hoses that attach to it is the lower radiator hose. It also has 6 to eight of the bolts that go through the pump, and thread into it. The small bolts that would be behind the water pump pulley.
