Re: serpentine belt ('87 YJ)
 

I would keep an eye on the alternator output. Dropping a volt or so can
mean a diode died which will put more of an AC wave into the output and
lower the DC power.

It also could just mean the belt is slipping some too....

You will know when you change it. Did you locate the adjusting bolt for
the PS pump on the bottom right of it? Watch out for that damn lock
bolt!

thanks mike - havent had the chance to do it today. i'll know
tomorrow... thanks to you and everyone else i can probably actually get
it done! i thought this whole procedure was going to take me 45
minutes. serves me right for thinking i know what the hell i'm doing.
cheers,

ps thanks to carl for the autozone link - thats quite a nice free
resource!

Hey Bennett,
It's me Kevin we have the exact same Jeep. That altenator is held in
by a two piece adjusting bracket (one in front and one in back) so it
is tricky to see what bolts are holding what. There are only 3 bolts
you need to loosen to free the alternator. While standing in front of
your Jeep and using the alternator as a clock face. The first is at
about 2 o'clock and it is located about an inch directly below your AC
compressor pulley. Ignore the obvious bolt you see there at 1 o'clock
, it just attaches the alt. to the front adjusting bracket. The second
bolt is at about 5 o'clock, this is the pivot bolt. Finally the last
bolt is on the BACK SIDE of the alt. at the bottom just an inch from
your fender well. This one you might want to remove completely since
it will bind up the works if the bolt or bracket are bent at all. You
then may have to pry up from underneath the Jeep to free it if it is
really old. The thing will only pivot about an inch or two at best,
but that should be plenty to remove and install the new belt. You'll
basically be pulling it up towards the center of the the Jeep to get it
to slacken the belt . When reinstalling if you have your stock lug
wrench that is mounted right there on the fender well, Slide the end of
that over the bolt there at 1 o'clock and push up with your left hand.
This forces the alt. down thus tightening the belt and you can tighten
those front two bolts with your right hand while keeping leverage on
the pry bar with your left. Then tighten the rear bolt last.
Good luck, I'd try this again before attacking the power steering pump
which was not designed to adjust tension on your belt system. Any luck
with that info on your emissions label under the hood? Let me know if
you have problems.

You can undo a flat 'serpentine' belt with the alternator????? He
doesn't have V-belts....
