i have the same problem, i noticed it a week or so ago, starting with coolant loss, but the past couple of days i've been running hot after about 40 mins of highway driving. had to limp it home yesterday from angleton, tx to my house in houston, about 40 or 50 miles. by the time i got home, my degas bottle was puking a little bit, nothing near as bad as when my oil cooler went bad last month. i'm guessing its the waterpump, the pulley itself spins off center compared to all the others. the truck has 131k, arp studs, new oil cooler, radiator, egr delete, afe stage 2, hypertech maxenergy, all done about a month ago. i also have oil spread around the front of the engine like it spat from somewhere, not sure where though. not AS worried about the oil, but i need to address it too. the coolant issue is more pressing because its keeping me from working. any news on what happened with your buddy's truck?

Sounds like the water pump to me as well. I have heard it isn't too difficult, just pull the fan, fan shroud and it's right there, although I haven't personally done it.

getting the fan clutch removed from the waterpump is always fun for do-it-yourselfers. it's left hand thread btw (lefty tighty)

i prefer a pneumatic fan clutch removal tool. never had to use anything else

fan clutch is 47mm or 1 7/8" will work also. actually OTC makes a water pump hub holding tool for the 6.0 but like i mentioned before, never had to use it
