The Dayco 5120985 is an automotive multi-rib serpentine belt with 12 ribs and a 42.16 mm width. Its 2501.9 mm effective length is the measurement to match against the belt you are replacing. Read the profile and the length together before you order.
The rib count sets the profile: 12 ribs across a 42.16 mm width. A serpentine belt must match the pulley grooves it runs in, so the rib count and width are the first check. The 2501.9 mm effective length is the second, and it is measured along the belt's working path rather than its outside circumference.
The marking on the back of the old belt is the fastest way to confirm what you need. If it reads 5120985, this is the belt. If it reads 12PK2500, that is the same belt under its alias. Send either number and we will confirm the match.
For a quote, send the part number 5120985 or the alias 12PK2500, along with the quantity. If the old belt's marking is worn or unreadable, send the rib count and the length you measured instead, and our team will help confirm the right belt or suggest an equivalent.
