Important Considerations

When working on your Tucson's serpentine belt, keep these points in mind:

  • Always use the correct belt size and type for your specific engine model.
  • Inspect the tensioner and idler pulleys for signs of wear or noise, replacing if necessary.
  • Check the crankshaft pulley for any play or damage, as issues here can cause premature belt wear.
  • Never force the belt onto the pulleys, as this can damage both the belt and the engine components.

To ensure longevity of your Tucson's serpentine belt:

  • Regularly inspect the belt for cracks, fraying, or glazing.
  • Listen for any unusual noises that might indicate pulley problems.
  • Replace the belt according to the manufacturer's recommended interval, typically around 60,000 to 100,000 miles.
