This Dayco 5140580 belt is a 14-rib automotive multi-rib (serpentine) belt with an effective length of 1474.98 mm and a width of 49.28 mm. It is used on engine accessory drives where a single belt routes over the alternator, water pump, air conditioning compressor and other pulleys. Because serpentine belts are matched to the drive layout, the reliable way to confirm fit is to compare the rib count, width and effective length against the belt you are replacing.
Start with the marking on the back of the old belt. If it reads 5140580 or 14PK1473, you have the same profile and length. If the marking is worn away, count the ribs across the belt width: this belt has 14. Then measure the effective length along the belt path and compare it to 1474.98 mm. A belt that is shorter or longer by more than a small margin will not tension correctly on the same drive.
On the vehicle, check that the belt sits fully in the pulley grooves and that all ribs engage. A 14-rib belt that is only partly seated, or that has been run with a misaligned pulley, will wear on one edge. Inspect the tensioner and idler pulleys at the same time, and replace the belt if you find cracks, missing ribs or glazing.
For a quote, send the part number 5140580 or the alias 14PK1473, along with the rib count and length from your old belt if you have them. Our team can confirm the belt against those details and suggest an equivalent if needed.

Frequently asked questions
- How do I know this Dayco 5140580 belt fits my drive?
- Match the rib count, width and effective length. This belt has 14 ribs, a width of 49.28 mm and an effective length of 1474.98 mm. If your old belt is marked 5140580 or 14PK1473, it is the same size.
- What should I check before replacing a serpentine belt?
- Inspect the pulley grooves for debris or damage, check the tensioner and idler pulleys for play or roughness, and make sure the belt routes correctly over every pulley. A worn tensioner can make a new belt slip or wear quickly.
- What information do you need to quote this belt?
- Send the part number 5140580 or the alias 14PK1473. If you are replacing a belt with an unreadable marking, send the rib count and the effective length measured from the old belt.
