serpentine belt ('87 YJ)
 

hey all - '87 YJ w/PS and AC (non-working)... water pump been going bad
for a few weeks and is now on its last legs - went to replace it today
with the less than helpful Haynes manual as a general guide and ran
into what seems to be a common problem - i was unable to loosen the
serpentine belt. now i was attempting to loosen the alternator but
after breaking every rusted old bolt loose on the damn thing it still
wouldnt budge - looking at it only confused me further because altho
there were clearly adjustment holes in the alternator bracket there
doesnt appear to be any way to actually pivot the alternator! i just
did a quick search on this in the list and found numerous references to
similiar problems with the answer being that one must use an adjusting
bolt on the back of the POWER STEERING PUMP bracket...
but - since all of these posts were for much later model vehicles than
mine i'd love a confirmation. i just cant bear to go out and look
around under the hood right now. i was ready to set fire to the damn
thing today after about 1.5 hours of hot sweaty dirty frustration...

so - belt is slackened and adjusted via the power steering pump
bracket?
gotta love that haynes manual: "slacken belt by loosening alternator
bracket pivot bolts - see section XXXX." which turns out to be two
extremely difficult to read photos and about a sentence.

maybe i'll just burn the book instead.

P.S. The AC is still all connected - it even blows when you turn it on
- just not cold air. good thing i live in Minnesota. :/

Re: serpentine belt ('87 YJ)
 

There is an adjuster bolt on the power steering pump bracket that tightens
the belt on later model 4.0L's. I would guess it's the same on the 4.2L. Are
you going to replace the belt at the same time?

Check out www.autozone.com , they have free repair guides. If one for your
Jeep doesn't come up, look at the one for a 90's Cherokee. It should be the
same.

Re: serpentine belt ('87 YJ)
 

Well, you have the odd ball 4.2 with the long belt. The manual is
referring to the V-belt engine, not yours.

You need to loosen the PS pump pivots and the bottom lock nut to loosen
a long set screw in the right hand side of the PS pump to loosen the
belt.

BUT! Why bother? I never loosen the belts when changing a waterpump.
I just pull out the pump and put the new one back in. The belt will
just go back to the same tightness it was before.
