The Dayco 5070840 is a 7-rib automotive multi-rib (serpentine) belt with a 24.38 mm width and an effective length of 2133.6 mm. It is the type of belt used to drive multiple engine accessories from a single pulley path on the front of an engine. Confirm fit by matching the rib count, width and effective length to the belt you are replacing.
Serpentine belts run across the accessory drive, turning components such as the alternator, power steering pump, water pump and air conditioning compressor from one continuous ribbed belt. Because a single belt often drives several accessories, a worn or damaged belt can affect more than one system at once. This Dayco belt has 7 ribs and a 24.38 mm width, and its effective length is 2133.6 mm.
The most reliable way to confirm fit is to read the marking on the back of the old belt and compare it with the part number 5070840 or the alias 7PK2135. Then check the rib count and the effective length against the data here. If the old belt is too worn to read, measure the effective length along the belt path and count the ribs before ordering.
Send the part number, the rib count and the effective length for a quote. If the marking is unclear or the belt is missing, send a photo of the routing and the pulleys, and the team can help confirm the right belt or suggest an equivalent.
