When should you change alternator on Nissan Xterra 2001?

Nissan recommends changing the alternator drive belt every 60,000 miles or 5 years, whichever comes first. However, you may need to change it more frequently if you drive in dusty or dirty conditions, or if you frequently tow heavy loads.

*Here are some signs that indicate that you may need to change the alternator drive belt:*

- Squealing or chirping noise from the engine compartment when you start the engine

- Dimming headlights or other electrical problems

- Battery warning light illuminated on the dashboard

- Difficulty starting the engine

- Overcharging or undercharging of the battery

If you experience any of these symptoms, it's important to have your alternator drive belt inspected by a qualified mechanic. If the belt is worn or damaged, it should be replaced as soon as possible to avoid further damage to your vehicle.

Here are some tips for extending the life of your alternator drive belt:

- Avoid driving in dusty or dirty conditions

- Don't overload your vehicle

- Have the alternator drive belt inspected regularly

- Replace the alternator drive belt as soon as it shows signs of wear or damage
