Don't recall who posted the belt size chart last week, but, it stated that for a 3.2 - 3.5 Grand Prix gtp use 660, Blue guy 91 states 665. Will these both work ? I purchased a Gates K060841. Thanks for your time.

Ahh dude,.. that belt comes up as a serpentine belt? I just put a 660 Gatorback on a 3.5. Oreillys list a totally different Gates belt for S/C. Where did you snag the belt from?
 
The 665 (actually 663 IIRC) belt is the stock length S/C belt, and should work down to a 3.6" pulley. A 660 (K060660 in Gates) is typically used for a smaller pulley down to 3.25"ish. That K060841 doesn't match any application for any year GP I can think of. It's too short for the S/C belt and too long for the accessory drive.

So if you used a gator back 660 wouldn't the Gates 060 be a 60" same as your gator back ?

I had a Gates 658 before on 3.5.....What exactly are you looking for? They do have a Gates 660....ZZP, Amazon or where do you want to get it from?
 
I bought a Gates k060841 I'm getting multiple size suggestions for a 3.5 pulley on 02 gtp.I don't know if the one I have is right or not.
 
1) stock for 3.8 k060663 http://www.oreillyauto.com/site/c/d...&ck=Search_k060663_1382521_-1&keyword=k060663

2) smaller for 3.5 k060660 Gates® Micro-V AT® K060660 - OEM Quality Serpentine Belt | O'Reilly Auto Parts

3) smaller yet for 3.5 k060658 Gates® Micro-V AT® K060658 - OEM Quality Serpentine Belt | O'Reilly Auto Parts

I went with #2 at first,5 years ago and just recently switched to a #3 size in a Goodyear. That belt you have, being a k060841, would be too big.

Picture of old 658, I keep them because they make an excellent strap wrench
