I am trying to help my neighbor repair his Taurus. He had an antifreeze leak from a pin hole where the heater hose connects to the elbow that connects to the lower intake manifold This elbow is the metal block that the sensors for the temperture gauge and computer screw into.
He ordered a replacement elbow Part # 17255 from Ford thinking it would screw into the lower manifold casting but it has no threads. It must be pressed into the manifold which is aluminum. We are afraid to try and remove the old one, and maybe break the aluminum manifold, without some more information on how to properly do it. None of the manuals we have looked at (Motors, Haynes, etc have any information on how to remove it.
If anyone has ever replaced one of these elbows or has access to a factory manual we would appreciate any information on how to do it without breaking something. there is a picture of the new elbow at:
