This Dayco 5030310 belt is a 3-rib automotive multi-rib (serpentine) belt with an effective length of 787.4 mm. The profile and length are the two numbers that matter most when you are matching a belt to a drive or comparing it against what came off the engine.
The 3-rib profile means the belt is built to run in a matching 3-groove pulley set, and the 10.16 mm width gives you a second measurement to check against the old belt. The 787.4 mm effective length is measured along the effective line of the belt, not the outside circumference, so it is the figure to use when you are reading a drive layout or confirming a replacement.
If you are working from the belt that failed, look for the part number on the back of the belt and compare it with 5030310. The alias 3PK0785 is also used for this belt, so either marking may appear. When the marking is worn off, measure the rib count and the effective length and send those along with your quote request.
