* Driving conditions: Extreme heat or cold, frequent stop-and-go driving, and dusty environments will shorten its life.
* Belt quality: Higher-quality belts generally last longer.
* Proper tension: A belt that's too tight or too loose will wear out faster.
* Maintenance: Regular visual inspections can catch wear and tear early.
Generally, you can expect a serpentine belt to last between 50,000 and 100,000 miles. However, it's crucial to inspect it regularly, ideally every few months or at least during every oil change. Look for cracks, fraying, glazing, or any signs of wear. If you see any of these, replace the belt immediately to avoid a more serious (and expensive) breakdown.
Don't wait until it breaks; a broken serpentine belt will leave you stranded. It's far better to replace it proactively within the recommended timeframe or when signs of wear are visible.
