Nice to know.. I ordered rpm version of Gates. Recommended by forum member.
I bought the newer 2 pulley bracket from Pace, the a/c belt coming off on a 90* day is a real pain in the ass and usually destroys belt. Haven't installed it yet, but real soon.
I would like to know what makes the factory belts stay on but the replacement belts fall off. What has changed in that time?

Plenty of variables such as time and various belt sizes. Over time a belt has a tendency to strech. A brand new belt tensioner has a higher propensity to keep everything snug. A stretched belt paired with a compromised pulley or inferior setup can create a problem(s).

So egg on my face. :D

I had the hood open this afternoon to look at something else, so I looked. Sure as ****, the A/C belt is halfway off... No real damage to the belt, what I think kept it on was that there is a little ridge on the harmonic balancer that wouldn't let it move any further forward. It just rode the idler halfway as well as the balancer and A/C compressor. :D

Not sure when or what caused it to take place. I changed the oil recently and it wasn't doing this at that point. So it's been recent.
