dumping coolant

[notchback]

long time lurker, 1st time poster. I just picked up a '91 F-250 4x4, 7.3, auto the other day for $300 due to it not starting. I traced the problem down to a broken wire on the starter. Put another on there and she fired right up. I started out on a couple hundred mile drive (I know, stupid without first testing it out all the way) and about 70 miles from home she started getting hot. I pulled over, refilled the radiator with water (since that was all I had) and limped home. I hopped on a greyhound bus to take the trip I needed to. Now I home. I filled up the radiator again, as it was low, and took it for a test drive. Went about 5 miles, came home and went to check the radiator and noticed coolant was spraying off the fan. I shut the truck down and let the coolant begin to run out. It's coming from under the front crank pulley. Is there something back behind that that can leak, or are my chanced pretty good that it's leaking from the bottom of the water pump. I can't see anything in there and don't want to tear into it and start working on the wrong thing.

Here's the truck in question on the way home. It fit on the trailer with about 4 inches to spare. Pulled it home with my neighbor's '88 F-350 7.3.

I'll bet it is your waterpump. I bought my 88 F-250 7.3L 4x4 about 200 miles away from where I live. Started driving it home and got about 20 miles from home and noticed the temp gauge was going up and steam coming out under the hood. Pulled off the freeway and water was pouring out as you describe. Had to have my son (with his Dodge Cummins) pull the trailer with my truck on it. Not fun. :>) I replaced the waterpump and it has been fine since.
