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:

You could ask the Ford dealer.

You may have to remove the intake manifold, which should not be that
hard. Then take it to a machine shop.

JUnkyard manifold?

Maybe drill out slightly and JB weld?

It's a press fit with LocTite applied. I've removed them by cross drilling the body and
using a pry bar to break it loose. Sometimes you can work them out after that.

Your best bet would probably be to cut it off, thread the piece left in the intake, and
use a slide hammer or make a puller out of a deep socket or pipe.

Hi

Looks like from the picture you might try putting a wrench on
it and try wiggling it back and forth while gently prying at it
with a screwdriver. I did something like this one. It eventually
comes out after a time. You need lots of that liquid wrench stuff,
and patience..
