Water Pump or Alt Pulley?

[rakfint]

I am now on my third belt within 500kms of driving.. First one I replaced because it was squeeling a lot when I bought the car.

Second one started to squeel and then a friend sprayed WD-40 on it so it burned out & snapped.

I am third belt in & I can hear it starting to squeel again.

If the bearings in the water pump or alternator are going will it cause this? If so, how do i determine which one it is?

Is there anything else it may be?

thank you all!

Oh also - there doesn't seem to be any leaks on to the belt..

Take the belt off and spin each component by hand and listen.

I wonder if your crank pulley is wobbling... what year is your car? small nose?

[rakfint]

I have spun them before - what am i listening for? I didn't really notice friction or noise when I did it last.

91 model... is this small nose?

The alternator pulley will cause this periodic stress on the belt if
Its going bad It locks up every once and a while until it locks up for good.

Or after you put a new belt on you should re tighten it after 100miles of driving

I did tighten the belt after about that amount of driving this time around.

maybe it is to tight??

[rakfint]

No it's about the half inch of movement that i've read is good. I had a mechanical friend check it out, he also said its a good tension.

I have a new waterpump sitting at home, just dont want to install it if not necessary :p

I had the same problem on my 90. The squeal disappeared after I changed the alternator. It was the only thing I hadn't changed. I'd try it first. You could spin it with the belt off and it sounded and felt fine. No strange noise, vibration at all.
