Good Maintenance Practices

  • Before purchasing and installing an engine harmonic balancer, make sure it is the correct size and fit for your vehicle.
  • Check the harmonic balancer for excessive movement or wobble.
  • Check for uneven wear on the drive belt, which can indicate that the balancer pulley is out of alignment.
  • Have your vehicle inspected as soon as possible if the ‘Service Engine Soon' light illuminates.
  • Have your vehicle inspected immediately if the ‘Service Engine Soon' light flashes rapidly, as this could indicate an engine misfire condition which may damage your engine and/or engine emission components.
