That hose!?!?!
[QUOTE=jbrew;3281877]Alright , heres some -
The O-Rings that go bad . Heres a pic of the recess in the water pump stem the O-rings ride in. Mine were so bad , they were just about disintegrated and aren't pictured. This pic was taken after the stem was cleaned up.

Water pump mod w/heater hose . If you do this mod , make sure you tighten the clamp on an angle so the clamp bolts aren't higher than the rubber fitting. If you don't the bolts hit the lower intake upon install.
Also if the heads pitted around the water jacket/jackets. Use some aluminum filler/sand smooth before re-installing the manifold.

Heater core hoses - These are the wrong kind I used at first. They fit good, but you have to band clamp the firewall inlet and outlet @ the heater core. This is insufficient and will loosen in time and blow off . You need the Ford replacement lines @ the dealership. Also that smaller hose plugs into the supply tube. that can leak in the same are above the starter.

that 3/8 looking hose coming out from the behind the intake. WHERE DOES IT GO? My hose corroded and broke off at the hardline and now i cant trace it to replace it.

3/8" hose that comes from the back of intake
I'm thinking you don't have the smaller hose. I believe the set up was changed in 99. I think you have a plastic manifold were mine is aluminum.
Anyway , that hose connects to the tree on the Throttle body elbow (Plenum) you can barley see where it's connected on the very left in this pic, below the Plenum bolt w/little clamp on it -
Yea , here's a 2000 throttle body and Plenum - No tree , doesn't have that small hose -
Yea, here's a pick of my old one , you can see the tree in this pic, on the left side of the plenum (elbow) -
