The Dayco 5040388 is a 4-rib automotive multi-rib (serpentine) belt with an effective length of 985.52 mm and a width of 13.72 mm. It is identified in the Dayco Poly V automotor series and also listed under the alias 4PK0985. Before fitting this belt, inspect the drive and its sheaves.

A new serpentine belt will not correct a worn or misaligned drive. With the old belt removed, check each ribbed pulley for damage, buildup or roughness in the grooves, and confirm that the pulleys turn freely and run true. Look for rust, debris or a polished glaze in the grooves, any of which can accelerate wear on a new 4-rib belt. Verify that the tensioner and any idler pulleys move smoothly through their range.

Confirm the replacement against the marking on the back of the old belt and against the drive layout. This Dayco belt has 4 ribs, a 13.72 mm width and a 985.52 mm effective length. If the routing or the pulley set has been changed, do not assume the old length still applies. Send the part number 5040388 or the alias 4PK0985 for a quote.

When you request a quote, include the belt marking, the number of ribs and the effective length so the team can confirm the correct belt. If the drive uses more than one belt, inspect all of them and replace them as a set so the load stays even across the pulleys.
