I have a 2001 F150 with the v-6 engine. A couple of days ago the truck started leaking water and overheating. I figured it was the waterpump so I replaced it, come to find out that wasn't the problem. When I was refilling the radiator water started pouring out and i found a broken aluminum elbow piece that connects the heater water outlet tube to the manifold under the throttle body. I got the replacement part but the problem is there is about an inch worth of aluminum pipe stuck in my manifold that i cannot get out. It is in a difficult spot an I do not have a lot of room to work with, any suggestions on getting it out?
Does the 2001 have the cast aluminum intake manifold?
If so, then I think I know the aluminum nipple you are talking about. It is used to circulate water through a small jacket in the intake manifold. If you look, you should see another nipple that returns the water from the manifold back to the coolant circuit.
Back when I had my 2000, I can't remember exactly why now, but I woud up just bypassing the circulation through the manifol. I hooked the "goes otta" to the "goes inta" and never had any problem or notice any difference in performance.
