Question breaking belts

:confused: My friend has a 1989 Mercury Topaz 4 cylinder w/air.
recently he change altinators and has broken 3 belts. The belt
drives the alternator and power steering. The pulleys on both
look to be running true. We insured the belt was tight, but each time the belt would start sqeeling by the next dayand break in about two days. Could it be a bad rebuild alternator and not be visible wobbling? Please help use figure this out, Thank You.

Were there any spacers removed during the R&R?

Is it the right unit?

Belt manufacturing defect possible.Take broken belt back to retailer and let him check it .Otherwise belt too loose so it burns.

I would say the only a few things that could cause this, a loose belt or a pulley that is freezing on the power steering or alternator or pulley alignment. Once you install the belt you should re-tension it after about 30 minutes of use...did you re-tension the belt? Are they pulleys lined up with each other when you look at them from the side, sometimes you can get an alternator on some cars installed on the wrong sides of the mounting brackets.

Go to this link and plug in 1989 Tempo, (Tempo same as Topaz)click on your engine size and go to Quickfind and click on "Belts" for more info on how to tension your belt.
