OE-designed belts will typically run 70,000 to 100,000 miles, however, it is recommended that all belts be inspected at about 50,000 miles and at every oil change after that, to ensure belt rib wear is still acceptable, as well as no failures related to edge cord fray/pop-out and/or rib cracking/chunk-out.
There are two main causes of belt noise: pulley misalignment causing an intermittent belt noise called “chirp” and low belt tension causing a continuous belt noise called “squeal”.
Belt wear can be difficult to detect because newer belts made with EPDM rubber tend to wear like tire tread, where there is material loss from the rib surface. A new belt will have a traditional “V” profile in the grooves between the ribs. On a worn EPDM belt, however, the groove profile will have the appearance of a “U”. If your belt has 90,000 miles or more, it is time to change it. Check out our video for a step–by–step guide to measuring belt wear.
