If you can’t always see or hear it, how do you diagnose belt wear? Think of belt wear the way you think of tire wear. After many miles of running on the road, a tire’s tread gradually wears down. Over time, belts experience a similar loss in material or rib wear. When this happens, a belt loses its ability to grip or function properly – it can slip – which puts a strain on other components within your engine, causing them to malfunction and eventually fail.
It is very important that you predict the failure on time, and to consider replacing the belt if your vehicle is:
- Older than five years, or
- Crossed a high mileage over the last several years.
The general recommendation is to follow the regular replacement intervals or to change the belt preventively after 60,000 to 160,000 miles or every 5 to 7 years but have not reached the specified mileage.
Do not wait for it to break- replace the belt in time to avoid expensive engine repairs!
