Green96GT Posted August 25, 2006 Share Posted August 25, 2006 As of last week I'm hearing a sort of 'whiring' noise from the engine. The pitch changes with speed. Sounds kinda like a tiny 707 is warming up for take off under there. I read an old thread about noise from the power steering pump. Could this be it? And oh, BTW, last week I changed the drive belt :-\ . I replaced the old frayed one with a "Gator" belt that has the diagonal ridges. Ya think it's the new belt? The package for the Gator belt says it's supposed to be quieter. Quote Link to comment Share on other sites More sharing options...
Manarius Posted August 25, 2006 Share Posted August 25, 2006 Does the car do it at idle? I think you might have a wheel bearing going... Quote Link to comment Share on other sites More sharing options...
subiefan Posted August 25, 2006 Share Posted August 25, 2006 Does it do it while parked? What about when the A/C on? A/C off? Get worse when turning the steering wheel? If it was the power steering, it probably would. It doesn't sound like the sound the ps pump make when the wheels are turned all the way in one direction, does it? I've seen the a/c compressor make what I'd call a whirring sound. Didn't do it when the a/c was off. BTW...what car and how many miles?

nipper Posted August 25, 2006 Share Posted August 25, 2006 yes what he said how many miles. COUld be an overtightened belt, a dying altenator. Remove the belt and see if it goes away. nipper Quote Link to comment Share on other sites More sharing options...

I thought I may have installed the belt too tight, so I loosened it and it makes the same noise. damage may be done. remove the belt makes sure it goes away. Take a can of wd 40 and spray the alt shaft, wee if it cheanges pitch. Same for the PS and AC compressor and the belt tensioner. Could be the (drive) belt tensioner going bad. nipper Quote Link to comment Share on other sites More sharing options...
Green96GT Posted August 30, 2006 Author Share Posted August 30, 2006 Dumb question: I can only get the noise to happen when the car is driving. Is it OK to drive with the drive belt off? I assume the only impact would be that it would be hard to steer. Nipper: are you saying that the over-tightened belt may have already fried the A/C compressor or the tensioner?

Nipper: are you saying that the over-tightened belt may have already fried the A/C compressor or the tensioner? yes you can drive the car with the belt off, but not for long. . The AC compressor bearing is fairly tough, but not so much on the p/s, and the alt is even more prone to failure for an over tightened belt. nipper Quote Link to comment Share on other sites More sharing options...
lmdew Posted August 30, 2006 Share Posted August 30, 2006 If you need a pump or alt I have them both. $25 each + shipping. Lmdew@hotmail.com. I'm in CO Quote Link to comment Share on other sites More sharing options...
