The Dayco 5070730 is a 7-rib automotive multi-rib serpentine belt from the Poly V automotor series. Its effective length is 1854.96 mm and its width is 24.38 mm. When you need to identify a replacement, start with the marking on the back of the old belt.

The marking on the back of a serpentine belt usually carries the part number and the rib count. Read the full string, including any prefix or suffix, and note the number of ribs. This belt has 7 ribs and a width of 24.38 mm, so a belt with a different rib count is not the same part even if the length looks close. Compare the marking to the Dayco 5070730 and to its alias 7PK1855.

If the old belt is worn or the marking is unreadable, measure the effective length and count the ribs before requesting a quote. The Dayco 5070730 is listed at 1854.96 mm effective length, 7 ribs and 24.38 mm width. Send those three values, or the part number from the back of the belt, and the team can confirm the right belt or suggest an equivalent.

Inspect the drive while the belt is off. Check the pulleys for alignment and the tensioner for smooth travel. Confirm that every rib runs in its groove and that the belt sits correctly across the full width. A belt that is the correct length but the wrong rib count will not seat properly, so verify the 7-rib configuration before installation.
