Belt help please!

[xsboosted]

Recently my car has developed a loud squalling in the belt system and I am taking it apart tommorrow to check each idler 1 by 1. I have searched and searched on my belt size, does anyone know an alternative to the belt with the part number 25-100852? The local napa can get it within 3 days but, is it a good belt to use? Thanks for your time

Could be the inner drive belt.

It will stop when you apply belt dressing or belt conditioner to the supercharger belt. I went ahead and ordered the 25-100852HD, green belt. Has anyone had any experience with this belt before?

Dayco part would be 5100855 for an 85.5, think the napa is 85 5/8
