LaMonte:
I have been following your post on your issue and can understand your frustration. Going back to what they had originally worked on, did the Fan Belt get checked for Proper installation (path). I know this might sound ridiculous, however, my first attempt at replacing my fan belt, I had routed it incorrectly using my memory. Once I compared it to my photo I took, my thoughts were, how could I mess this up. I never started the engine with the fan belt miss routed, so I don't know what the result would have been. What I do know, is that it was miss routed and it looked right but had a little too much slack to my liking so out came the photo.
One more bit of info: I have used this Cat Company several times, and Every time, there was an issue. My trust with this particular Cat facility, (St Augustine & Daytona), has been diminished.
