t-stat leaking

Just came home for lunch to trade trucks. Looks like my 2004 F-350 6.0 have a severe water leak. It looks like the pulley had wore a hole in the bottom of the t-stat housing.Does the housing come off by itself? Or is it part of the intake? Can't see how the housing could move, but maybe? If the pulley was wore it should move away from the housing due to belt tension?How hard is it to remove the housing? I'll be back later, thx in advance Jim

Ok, I'm back. Motor dried off a bit, no longer hotter than the hubs of hell. Got the flashlight out, removed the belt. No longer looks like the bottom t stat housing. Must have been the fan blowing the water or the belt throwing it there. Added water (distilled) and it's dripping off the harmonic balancer. Can only be the water pump, right? So when I get time I'm tearing it apart. What else needs to be done while I'm in there? T-stat. belt, hoses.Check the idler pulley bearings. It was recently flushed. Thought while the radiator was out I would stuff the garden hose in it and see how much crap falls out. Any heater hoses nearby I should change? And am I right, must be the water pump? Dark beer for this adventure?

I been looking at threads on here reguarding waterpumps. It's either a 30 minute easy to do or a 4-6 hour ordeal. Guess I'll find out.

well done with the water pump. Not too bad really. Hard to believe the old one leaked that bad, while running it was like a garden hose. Even with the Deguass cap off. In 2004 they list two water pumps, the expensive one is the improved one. At least I got the better one. Replaced the t-stat while in there, what a pain, the nut didnt come out the stud did, well almost did, it hit the fuel line right above it before it came out. Creative swearing got it out and a little grinder work shortened it enough to go back easy like. Found a new Ford tool. I needed an off set cheater bar for the pipe wrench that was on the fan nut. Didn't want to use a 5 lb hammer to smite it. I have a "Hickey stick", a rebar bender. Works like a champ for an off set cheater!

update

Put everything back together, worked great,but. could not get a good seal on the top hose where it goes into the rad.I had reused the spring type clamp. Replaced it with a screw type. Still leaked. Tried a dab of gaskacinch goop on the inside, still leaked! Ok, so the old blind man put on his glasses, grabbed a flashlight and peeked. What I found was a cracked radiator under the hose nozzle.New radiator off of Ebay and I'm all better. Now for maybe good news. For some time now under heavy load, towing, hills etc , I been puking out of the deguass bottle. Figured it was the dreaded head gasket issue. Even had it at Bullet Proof and their best guess was head gaskets.How did I know it was puking? Well the tell tale white spots and wet area around the bottle.And using water.Since the new rad it seems to have stopped. I havent towed anywhere yet, but have been out of town and up some good hills. I'm hoping that the crack on the rad was blowing water, with the aid of the fan, on the Deguass bottle.Time will tell. I am due for a break if the matters. Having to replace several plastic tank radiators over the years I can't help but wonder who the idiot was that decided to use them? Or just a case of cars and trucks being designed to just last warrentee period?
