The Dayco 5040323 is an automotive multi-rib serpentine belt with 4 ribs and a width of 13.72 mm. Its effective length is 820.42 mm, so the profile and length are the two figures to check first against your drive layout.

For a maintenance or purchasing professional, the profile is what narrows the field. Four ribs at 13.72 mm width identifies the belt as a 4-rib serpentine, and the 820.42 mm effective length is the measurement to match against the routing on the engine. Both values come straight from the belt data, so they can be compared directly with the old belt's marking.

The part number 5040323 is the reference to quote, and the alias 4PK0820 is also listed for this belt. If you are replacing a worn serpentine belt, note the rib count, the width and the effective length before ordering, and confirm the routing and tensioner condition at the same time. We carry Dayco belts and can help confirm the right belt or suggest an equivalent when you send the part number by WhatsApp or email.
