The Dayco 5070505 is a 7-rib automotive multi-rib serpentine belt with an effective length of 1284.99 mm and a width of 24.38 mm. The rib count and length are the two values that decide whether this belt will seat correctly and run at the right tension on your drive. This page gives you the profile data you need to match the belt to the application before you request a quote.
The 7-rib profile means the belt runs in a seven-groove pulley set, and the 24.38 mm width is the across-the-ribs dimension for that profile. The length is given as 1284.99 mm effective length, which is the working length around the pulley path rather than a raw outside measurement. If your drive was built for a 7PK1285, those are the numbers to compare against.
The part number 5070505 is the number to reference when you contact us, and 7PK1285 is the same belt under its profile-based alias. We carry Dayco belts and can confirm the right serpentine belt for your drive or suggest an equivalent when you send the part number, the rib count and the length from the old belt.
When reading a worn belt, check the back for the marking and count the ribs before ordering. A belt that is the wrong length or rib count will not sit correctly in the pulleys, so it pays to verify the effective length and width against the data here. Send the part number and any marking from the old belt and we will reply promptly.
