[QUOTE="Beltman, post: 10982492, member: 126919"] [b]Dayco Poly Cog[/b] I'm the Director of Marketing for Dayco Products in North America. A few years ago we changed our national brand serpentine belt construction from Poly Cog to Poly Rib "W" belts. Why? Today's belt are now made with EPDM rubber to last 100K miles. Today's OE belt drives are not created equal and some can be real demanding. Since these EPDM belts have stiffer charactoristics, they are prone to make noise with slight misalignments. Dayco engineers created the "W" Rib to allow the stiff rib to conform to slight misalignments and not make noise. Every manufacturer was forced to make this change to EPDM and everyone faced noise issues. The change from Poly Cog to Poly Rib was a running change as inventory ran out. This started in 2007 so lots are gone. AutoZone and Advance may still have your number. Email me if you are willing to try the Dayco Poly Rib W. I'll send you one only if you promise to brag on how good it performs. :) By the way, great forum. Hopefully this information helps. [/QUOTE]
