Instead of replacing it based on mileage, inspect the belt regularly. Look for:
* Cracking: Small cracks are normal, but larger, deep cracks indicate wear and impending failure.
* Fraying: Similar to cracking, fraying edges show significant deterioration.
* Glazing: A shiny, smooth surface suggests slippage and impending failure.
* Wear: Uneven wear or obvious thinning are warning signs.
* Proper Tension: The belt should have the correct tension (check your owner's manual for specifications). Too loose or too tight is problematic.
If you see any of these signs during your inspection, *then* it's time to replace the belt. Otherwise, with such low mileage, it's probably fine for many more years. However, a visual inspection every 3-6 months is recommended as a preventative measure.
