The Dayco 5120399 is a 12-rib automotive multi-rib (serpentine) belt with an effective length of 1013.97 mm and a width of 42.16 mm. Before you fit it, inspect the drive and the sheaves it runs on.
A new serpentine belt will not correct a worn drive. With the old belt off, check each sheave for rust, burrs, nicks and debris in the grooves, and confirm the ribs are clean and undamaged. Turn the pulleys by hand and check the bearings on the driven accessories for roughness, play or noise.
Confirm alignment across the drive. Pulleys that are out of line or a tensioner that no longer holds correct tension will wear the edges of a 12-rib belt and shorten its service life. Correct any misalignment or worn component before the Dayco 5120399 goes on.
The belt measures 1013.97 mm effective length and 42.16 mm in width, with 12 ribs. When you request a quote, send the part number 5120399 so we can confirm it against your application.
