The rib count and the effective length are the two figures that identify this belt, so if the marking on the back of the old belt is readable, send a photo or write down the numbers exactly as they appear. If the belt is worn or the marking is gone, measure the width and count the ribs.
The Dayco 5040340 has 4 ribs, a width of 13.72 mm and an effective length of 865.12 mm. These values describe the belt itself. They do not tell you which accessory drive it fits, so the safest way to match a replacement is to compare the old belt with the data above before ordering.
If you are replacing a serpentine belt, inspect the pulleys and tensioner at the same time. A worn tensioner or a misaligned pulley can damage a new belt. Send the part number, the rib count and the length you measured, and our team will confirm the belt or suggest an equivalent.
