The question that begs to be asked here is:
What name brand of belt are you guys using? I
USED To have this problem too on my Metro until:
1. I Took the
cheap belt off the car that was the ONLY one Autozone stocked (A
Kelly Springfield belt that
squeeled ALL the time)....And the 1st New one broke after only 4 months on the car and left me stranded at 11:00 at night on the freeway!....
2. Bought a higher grade "
Dayco Poly Cog" belt from Advanced Auto parts / Parts America......
Part # 5030323
3. Cleaned all the pulley grooves of Dirt, Grease and Oil with brake parts cleaner, Then cleaned out the pulley grooves good with Steel Wool to knock out any built up rubber debris......Re-sprayed them again with Brake parts cleaner. Cleaned and Steel wooled the adjustment bracket slot area where the Alt ear makes contact with the bracket on top during tightening.
4. Took the bolt/nut out of the Alternator that goes thru the adjustment slot bracket (Top of Alternator...See Pic).
5. Went down to reliable hardware store that stocked grade 5 or better Metric bolts, And bought a new grade 8 Bolt, but a 1/2" longer and sleeve type as the original factory bolt (Smooth collar of the bolt goes thru the alternator and adjustment bracket).
6. Also bought a "Nylon Filled" grade 8 locking nut, 2 "Thick" flat washers and 2 of the round Star locking washers.
7. Installed the bolt with the Flat washers going on 1st, then the locking washers so they were up against the adjustment bracket on both sides. In the order on the bolt: Flat washer, Locking washer-----> Put the bolt thru Alt and Bracket------> Locking washer, Flat Washer, Nut.
8. Installed the Dayco Belt, then tightened down the belt good, but do NOT Overtighten it!
It's been over year and a half since I tried this method.......No squeeling belt anymore and the belt has finally wore enough to validate me to retighten it up a little-------> But it still doesn't squeel!
Dayco Poly Cog Belt
Location of round washers, and washers with teeth on them are used
