dhs1223 Posted January 16, 2007 Report Share Posted January 16, 2007 I have a 1995 Cutlass with the 3.4 DOHC engine. There is a pulley or pulleys that have gained the ability to predict the weather. When it is dry all is quiet. When the humidity rises or when it rains the noise begins. The noise (chrirping/squeaking pulley)starts when the engine is warmed up and is most noticable at idle. Increase the engine speed and the noise all but disappears. I replaced the belt tensioner early last year, and I suspect this is the culprit. Does anyone have any input on this. Any ideas would be appreciated as the noise is really annoying and we are in winter in Georgia which means alot of rain, and I don't want to listen to this noise anymore.

Psych0matt Posted January 16, 2007 Report Share Posted January 16, 2007 when you replaced your tensioner, did you replace the idler pulleys? My belt finally went not because the belt was bad, but one of my idler pulleys completely crapped out. If you didn't do those I would definitely check on them. Possible it's your tensioner, too, but if it was newer I wouldnt suspect it as much. Quote Link to comment Share on other sites More sharing options...
Dirty Rockstar Posted January 16, 2007 Report Share Posted January 16, 2007 My 3100 is amking the same noise.. I have it narrowed down to the Alternator (Began shortly after I installed an amp and sub) or the idler pulley.. I know it is a pulley/belt issue because it happens at a constant rate.. I can predict when it will happen at each revolution.. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted January 22, 2007 Report Share Posted January 22, 2007 pull the serp belt and spin each pulley separately, that should help you narrow it down Quote Link to comment Share on other sites More sharing options...
DOHCRagtopguy Posted January 22, 2007 Report Share Posted January 22, 2007 You can also use a long screwdriver as a stethoscope, put the metal edge on various areas of the engine while it is running with your ear on the handle end, you can hear the bearings very clearly and will be able to narrow it to the bad one.
