I did take some pictures like you suggested, but also decided to come up with some belt routing diagrams as well. Now when I am standing in back of the coach on a dark cold night it might be a little easier to change one. My engine has four (4) belts. FYI only.
Yes, that’s exactly how I change the other three belts, but this one as shown in the picture doesn’t have a tensioner. It basically goes from the bottom pulley up to the AC compressor pulley and the only thing I can see to move is the entire AC compressor but it’s gotta be easier than that.
That’s a good point. I did notice the square hole but I thought it was a double pulley but I’ll give it a try. Thanks for the suggestion.
Just to bring this to a conclusion ... I did reach out to Spartan and they confirmed that there is not a tensioner on this belt and the way to change it is to loosen the four (4) bolts on the AC compressor that bolt it to the engine to get enough slack to remove the belt. So at least I know the correct way if I ever have to do it.I decided to just make sure I had all the tools needed and knew how to change the belts while it was sitting in my garage and have it all figured out except for my AC belt. It is a single dedicated belt and for the life of me I can figure out how to loosen it without removing the four (4) bolts that hold the AC compressor to the engine. Here is a picture. The bottom pully is a double pully that is connected directly to the water pump. Anybody ever changed this belt? It it is on the 500 HP engine.

If you have a Prevost you should be aware that the four belts are tensioned by small airbags. There is a hand valve that you turn to "vent" and that deflates the airbags so you can just remove the belt, put the new one on and return the hand valve to its normal position. No tools are needed, they have to be the easiest belts to change.
