Grinding or Whirring Noise From the Alternator on Honda Civic Si

Problem Description and Possible Solution

The 1999-2000 Honda Civic Si is known for premature alternator bearing failure. The alternator shaft bearing alerts of mechanical failure by making a howling or grinding noise, but other symptoms may appear, including:

  • Battery warning light illumination
  • Engine will not start
  • Engine stalling or hesitation
  • Power steering and A/C failure

    Continued use after the alternator makes these noises generally result in loss of the serpentine belt, power steering, air conditioning and battery power.

    The correction is to replace the alternator immediately.
