This Dayco 5121140 is a 12-rib automotive multi-rib (serpentine) belt with an effective length of 2895.09 mm and a width of 42.16 mm. It is also listed under the alias 12PK2895. Serpentine belts drive multiple accessories from a single path on the front of an engine, so fit is confirmed by rib count, effective length and width.
To confirm fit, compare the marking on the back of the old belt with this part number and check the rib count and effective length against the data above. A 12-rib belt must match the pulley grooves exactly, and the effective length must match the original specification. If the old belt is worn or the marking is unreadable, measure the rib count and the length along the belt path.
When requesting a quote, send the part number 5121140 or the alias 12PK2895, plus the rib count and effective length if you have them. Our team can confirm the belt or suggest an equivalent based on the profile and length you provide.
Inspect the drive for misalignment, worn pulleys or a failing tensioner before installing a replacement. A serpentine belt that runs out of alignment or under incorrect tension can wear quickly. Replacing the belt as part of scheduled maintenance helps avoid unexpected downtime.
