Radiator hose?
I have a rubber hose that goes out near the passanger side of the radiator, I'm not sure where I plug it into, do I put it into the EGR valve or does water not go into there? Where does the hose go? This is on a 1993 Bronco 5.8l

Welcome to FTE and the Big Bronco Forum. We will endeavor to get you the most accurate information we can muster.
By 93 the overflow tank is a dual purpose unit holding overflow coolant in one side (inboard) and washer fluid in the other (outboard). However it is located on the driver's side of the truck.
A bit more info on this if you please... approximate diameter of the "hose" in question? If this ends up being a vacuum line you certainly don't want to dip in in the coolant reservoir and wreak havoc on the engine.

On my 1994 5.8L, there is a 3/8" coolant hose that is clamped to a fitting on/by the throttle body, the EGR valve is right near it. This hose then proceeds forward, hanging off into space, then is crimped onto a 3/8" steel tube that runs crosswise above the radiator, from passenger side to driver side. At the drivers side end of the steel tube, there is a short length of hose crimped on it, that hose segment is then clamped onto a port on the radiator's filler neck.
This is a return line for coolant that either warmed the throttle body, or cooled the EGR area. I am doing this from memory, I would have to look tomorrow to see which function it actually does.
There also is a 3/8" coolant supply hose that comes out of a coolant port on the lower intake manifold, and runs up to the throttle body area. It is the source for the coolant return circuit I described above.
There may be some differences somewhere from the 1993 to the 1994 5.8L upper intake manifold, etc., as mine have F4 part numbers cast into them.
