I'm Hearing Noises!
My '93 SE has just developed a clattering or chattering noise at idle. It is intermittent, too. It'* coming from the passenger side of the engine, so I suppose it'* one of a few things: alternator, water pump, or harmonic balancer (or perhaps something else driven by the serpentine belt. What specific characteristics of each of the above will help eliminate that item? Looking under the hood, it'* difficult to pinpoint the noise, other than to say it seems like one of the above.If I turn on the AC, there is no change in the noise. It'* hard to determine if the noise goes away at higher RPM'*, but I think that it may be less. Hard to tell. BTW, there are no leaks, the oil pressure is 40 @ idle, and up to 80 when driving. Water temp is good and charging is fine. The belt itself looks good. The water pump was changed a few years ago, as was the alternator. The car has 187,000 miles on the clock.
Thanks for the help!
