What size belt do I need for a 3.6 pulley?

07 grand prix gt, belt size?? I was told stock belt would work but its really loose...

 

[gtpeddie]

should be fine i doubt it would be that loose at all, and your top swapped?

Probably just need a new belt... Probably the original one...

I think a 685k6 I can check and let u know what I'm running on my 06

Stock belt honestly will work on a 3.4".

Been there, done that.

Just toss the stock belt back on the 3.6", there isn't that much difference.
