Main, this thing is a PIA. Somewhere in the mid point of changing all of the different pulleys I changed the belts, it's not that old, maybe two weeks at most.
One thing I have to say about the new serpentine belts is they are a lot easier to work with than the belts on my panel with the flat 8. Man, trying to tighten the generator/ water pump belt is a HUGE PIA, then trying to get the fan belt tight only adds to it. After I got the belts on the panel the fan was hitting on the bottom of the opening of the fan shroud. I ended up making longer bolts for the motor mounts and using washers to raise the front of the engine about 1/2".
