coolant leak behind engine fan?

[arrowstrap]

i have a radiator fluid leak that is most heavy when the truck is tilted forward and/or when its warm out with the engine off. i have not noticed any leakage when the engine was running.

in poking around i discovered it was generating from behind the engine fan.

has anyone had similar issues? any ideas on what the repair would take?

IMO your water pump has gone T.U. R/R'ing a water pump isn't that bad, provided that you have the right tool to remove the (reverse-threaded) fan clutch.

you think it's the water pump and just just the gasket? what are some other effects of a bad pump?

BTW, thanks for the tip on the "right tool". i despise getting neck deep into a project to find i've got to hitch a ride for undisclosed parts or tools.

What is the right tool? I removed my brother's WP with the fan on and removed the fan when I could get the whole thing in a vise. In case I need to do my own, I would like to know what I was missing.

Thanks

It is 1.875" I took mine to a machine shop I used to work at. I may make a wrench out of a piece of 1/4" plate and a piece of oak for the handle.

My water pump failed without warning. One of the bearings went and the belt pulled the pulley over so far it chewed a groove in the casting.

Take the belt loose, grab hold of the fan and see if ya have any play.

I am bettin you do.

Arrowstrap, The last water pump I changed started to leak out the overflow hole in the front of the housing. I normally use a 1 7/8" wrench to remove the clutch fan but they do make a proper tool for it. A wrench works well as long as leave the belt on and remember it is reverse tread.

How you do keep the pulley from slipping in the belt?

I usually use a hammer and whack the wrench a couple times until it breaks free. I have taken them off before by also holding a fair amount of tension on the tensioner but most of the time they need a good whack on the wrench to crack them free.

I take fans off all the time to work on em at work, not powerstrokes only, other stuff too, and never use anything but a wrench, KNOCK ON WOOD........they always come off for me, but then it is much faster than bunch of patty whack tools, and on flat rate TIME IS MONEY.
