[DML] Re: Alternator Belt

["dmcjosh85" <dmcjosh85@xxxxxxxxx>]

I replaced my alternator about a month and a half ago and at first it 
had the same noise. a constant high-pitched whistling noise followed 
by a squealing scream when I gave it some gas. I didnt have to 
replace the belt since the one I had there was already quite new from 
the previous owner and looked to be in good condition. It took me a 
little bit to think that the belt just isnt tight enough. So I got 
under the car and using a long screw-driver I placed it inbetween the 
alternator and the alternater housing bracket and just gave it some 
good muscle. I got it as tight as it would go and had my grandpa 
tighten the bolts so it locked it in place. After that the whistling 
went away about...80% (only makes the sound during idle) id say and 
the squealing when giving it some gas was completely gone. I did come 
across a bottle of belt noise reducer in the garage and applied that 
which greatly helped out. since than the noise is only a small 
whistle when at idle and my voltage is consistant (even on a going 
bad battery and a electrical guage that needs to be cleaned for 
greater accuracy)

I also heard that getting rid of that belt noise can be done by 
getting a wet bar of soap and rubbing it on the the teeth of the belt 
as the car runs. Not sure what to think of this method but its what 
I've heard. 

Hope it helps!
