The Dayco 5040440 is a four-rib automotive serpentine belt with a 13.72 mm width and an effective length of 1119.89 mm. It is also listed under the alias 4PK1120. This type of belt drives accessory systems on passenger cars and light trucks, where a single multi-rib belt runs the alternator, water pump, power steering pump or air conditioning compressor from the crankshaft pulley.

To confirm fit, read the marking on the back of the old belt and compare it with the part number, the rib count and the effective length. The 5040440 has 4 ribs and measures 1119.89 mm. If the old belt is worn or the marking is unreadable, count the ribs and measure the effective length along the belt path before ordering.

Inspect the pulleys and the automatic tensioner at the same time. A belt that is the correct length but shows rib damage, glazing or edge wear usually points to a misaligned pulley or a weak tensioner. Replacing the belt without checking those parts often leads to a repeat failure.

When you request a quote, send the part number 5040440 or the alias 4PK1120, the rib count and the length from the old belt. If the exact number is not what you need, our team can help confirm the correct belt or suggest an equivalent.
