Alert Serpentine belt failures

Are you sure that that bottom pulley is not also a tensioner? Usually when there is a square hole in front it is meant to allow you to attach a 1/2” bar to apply pressure to release the tension. My 2017 does not have the same setup as yours so I could be wrong.

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.

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.

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.

What a PITA. I have Prevost check my belts annually so hopefully I am not on the side of the road changing my belts and I carry extra just in case.
