I replaced the fan clutch on our coach in 2010 while on our way to Yellowstone. Mine wasn't squealing; it wasn't engaging at all. I left a truck stop after refueling, and within 5 minutes, noticed the temperature started rising. Pulled off the road and verified the fan was not working. Ordered the clutch from Prevost about 4:45 in the evening and received it at 10 the next morning. We were back on the road by about 1:30, but it was rather demanding on my old body. Fortunately, it sounds like it wasn't nearly as bad as the H3. I didn't have to remove the radiator. It was hard trying to position that much weight and bulk of the fan and clutch at a 90 degree angle while getting it out and back in the fan shroud. Mine was $1600 for the fan and about $200 for the overnight delivery. Prevost advised me that I could place the bolts in the fan and it would turn all the time; but I decided to just fix it while I was there, and it worked out very well.
