However, a good general rule of thumb is to replace it every 60,000 to 100,000 miles (96,000 to 160,000 kilometers), or every 5-8 years, whichever comes first.
It's crucial to inspect the belt regularly. Look for:
* Cracks or fraying: This is a major sign of wear and tear.
* Glazing or shine: A very smooth, shiny surface indicates slippage and impending failure.
* Worn edges: The edges shouldn't be frayed or noticeably thinner than the middle.
* Stiffness or brittleness: A belt that's become hard and inflexible is likely to break.
If you see any of these signs, replace the belt immediately, even if it's not yet reached the recommended mileage. A broken serpentine belt can lead to serious engine damage.
