This Dayco 5100678 is an automotive multi-rib serpentine belt with 10 ribs and a 35.05 mm width. Its effective length is 1720.85 mm, which is the dimension to match when comparing it against the belt you are replacing. The part number 5100678 and the alias 10PK1720 both identify this belt.
The profile is the first thing to confirm. A 10-rib belt runs on a 10-groove pulley set, so the rib count and the 35.05 mm width have to line up with the drive before anything else is checked. This is a Poly-V belt, also called a multi-rib or serpentine belt, and it is built for accessory drives that use one continuous ribbed belt across several pulleys.
Length is the second check. The 1720.85 mm figure is the effective length, not an outside or datum dimension, so compare it against the same measurement on the belt coming off the drive. If the old belt is stretched, worn or unreadable, the part number on the back is the most reliable starting point.
Send the part number 5100678, or the alias 10PK1720, by WhatsApp or email and the team will confirm the belt and quote it. If you are unsure which number you have, a photo of the marking on the back of the belt and the rib count is enough to work from.
