The Dayco 5050405 is an automotive multi-rib serpentine belt with 5 ribs, a width of 17.27 mm and an effective length of 1029.97 mm. When you read the marking on the old belt, match those three figures to this listing before you request a quote.
The marking on the back of a serpentine belt usually carries the part number and the size. On this belt, the part number is 5050405, and the aliases field lists 5PK1030. The size to confirm is 5 ribs, 17.27 mm width and 1029.97 mm effective length. If the old belt is worn or the marking is unreadable, measure the effective length and count the ribs instead.
Send the part number, the rib count, the width and the effective length with your quote request. A photo of the marking on the old belt also helps us confirm the right belt or suggest an equivalent. We carry the Dayco 5050405 and serve maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America.
Before installation, inspect the pulleys for wear, misalignment or debris, and check the tensioner and idler pulleys. A serpentine belt that runs on worn or misaligned components can fail early. Replace the belt as part of the drive service, and confirm the routing matches the diagram for the application.
