Read the marking on the back of the old belt and compare it to these figures before you request a quote.

Markings on a serpentine belt are printed on the back, and they can wear off before the ribs show damage. If the print is gone, measure the effective length and count the ribs instead of guessing from the vehicle. On this belt the rib count is 10, the width is 35.05 mm and the effective length is 2133.6 mm.

A serpentine belt that has lost ribs, glazed or cracked should be replaced rather than reused. Inspect the pulleys and the tensioner at the same time, since a worn tensioner or a misaligned pulley will shorten the life of a new belt. Confirm the routing matches the drive before the belt is fitted.
