The Dayco 5030440 is an automotive multi-rib (serpentine) belt with 3 ribs, a width of 10.16 mm and an effective length of 1119.89 mm. This profile is commonly used to drive accessory components on compact engine layouts. Confirm fit by matching the rib count, width and effective length to your original belt.

Multi-rib belts like this one are used on front-end accessory drives to turn components such as alternators, water pumps, power steering pumps and air conditioning compressors. The 3-rib, 10.16 mm width and 1119.89 mm effective length identify the physical size of the belt. Because different engines use different pulley arrangements, the same length can appear with different rib counts, so always verify all three dimensions before ordering.

The most reliable way to confirm fit is to read the marking on the back of the old belt. If the marking matches 5030440 or 3PK1120, the replacement is the same size. If the marking is worn or missing, measure the effective length and count the ribs on the old belt. You can also compare the belt routing diagram on the vehicle or in the service information to confirm the number of ribs and the path around the pulleys.

When requesting a quote, send the part number 5030440 or the alias 3PK1120, along with the rib count, width and effective length if you have them. If you are unsure, send a photo of the old belt marking and the vehicle information. The team can help confirm the right belt or suggest an equivalent.
