When you read a serpentine belt marking, the rib count and length are the two figures that decide whether the belt will sit correctly on the pulleys. This belt has 4 ribs and a 13.72 mm width, so it is a 4-rib profile. The effective length is 960.12 mm, measured as effective length. Compare those two values with the belt you are replacing before you request a quote.

If the old belt is worn or the marking is unreadable, count the ribs across the belt back and measure the length as shown in your drive layout. The Dayco 5040378 is the reference for this profile and length. Send the part number 5040378, or the profile and length, and the team can confirm it against your application.
