I bought a 1986 F-150 with a <a href="http://www.motorhaven.com/">302 </a>EFI engine. The fuel pumps were not working and it turned out to be the hot wire that attaches to the selonoid. The radiator appeared empty. When I started the truck(because I was more concerned with getting it started first) it started leaking cooland off the back side of the motor and onto the tranny. When I fill the radiator up with the motor OFF the coolant is running onto the ground from somewhere behind the motor or plenum. I can't find it and it is leaking bad. Is there a coolant system diagram somewhere online? What could cause coolant to run on the ground from back there without the motor running? Please Please Please anybody.
Are you sure it is coming from the top of the motor and not out of the bellhousing? I would recommend getting back there with a flashlight and watching while someone pours coolant into the radiator.
Where would the coolant be coming from if it was dripping out of the bell housing? My <a href="http://www.motorhaven.com/">302 </a>has a slight rear main seal or transmission seal leaking but also a small amount of coolant on the floor ocasionally.
Well I pulled the plenum off and found a hole in the intake manifold near the farthest back injector on the passenger side, the hole is about the size of a pencil eraser. Any chance of a shop patching the hole? What would be a good price for a used intake manifold?
Unlike cast iron, aluminum can be welded very easily with a shop set-up to do it. But check the junkyards first.
I went to www.car-part.com and plugged in your truck in the state of New York. I selected intake manifold, 5.0 lower, and got prices from $30.00 to approx $120.00.

Thanks, if I could get one for that cheap I might as well replace it so it doesn't leak again. Car-Part.com rules! How do I know what tranny I have in my truck. It says Metric Automatic Overdrive on the pan?
Look on the sticker in the door jamb and find the TRANS code (a single letter). E is the E4OD; K is the C-6; T is the AOD; U is the 4R70W (electronic version of the AOD).
