The Dayco 5040437 is an automotive multi-rib (serpentine) belt with 4 ribs, a width of 13.72 mm and an effective length of 1109.98 mm. This type of belt drives accessory components on an engine, such as the alternator, water pump, power steering pump or air conditioning compressor, depending on the vehicle layout. Use the rib count, width and effective length to confirm it matches the belt you are replacing.

To confirm fit, compare the marking on the back of the old belt with the part number and the 4PK1110 alias. Check that the old belt has 4 ribs and that its effective length matches 1109.98 mm. If the old belt is worn or the marking is unreadable, measure the rib count and the effective length along the belt path.

A serpentine belt should be inspected for cracks, glazing, missing ribs or frayed edges, and the tensioner and pulleys should be checked at the same time. If the belt has been running with a worn tensioner or a misaligned pulley, replacing the belt alone may not correct the noise or slip.

We carry the Dayco 5040437 for maintenance, engineering and purchasing teams in the United States, Canada, Mexico and South America. Send the part number, the 4PK1110 alias or the rib count and effective length by WhatsApp or email, and the team will reply promptly to confirm the right belt or suggest an equivalent.
