The Dayco 5040373 is a four-rib automotive serpentine belt with an effective length of 946.15 mm and a width of 13.72 mm. If you are replacing a worn belt, the fastest way to confirm you have the right one is to read the marking on the back of the old belt. The code printed there, often something like 4PK0945, tells you the rib count and the length.

On this belt, the marking identifies a 4-rib profile and a 946.15 mm effective length. The 4PK0945 alias follows the same logic: four ribs, and a length that matches the 946.15 mm figure. When the old belt is still legible, copy the full string exactly as printed and match it against the Dayco 5040373. If the printing has worn off, measure the rib count and the effective length instead, or send us a photo of the belt routing and any remaining characters.

We carry the Dayco 5040373 as a four-rib serpentine belt for automotive accessory drives. It is listed with a 13.72 mm width and a 946.15 mm effective length, measured on the effective line.

If you are unsure whether this is the correct belt for your drive, include the vehicle or equipment details and the old marking, and our team will confirm the match.
