Re: how to put on belts
You should be able to find a black sticker under the hood, usually on a body or trim part, sometimes on the engine near the belt, that is the "belt routing diagram" this shows preciseky how the belt is to go on.
you will also need a 1/2" drive breaker bar with a few 6-point sockets ranging from 13mm to 18mm, and also it would be safe to have a 1/2" to 3/8" socket adapter there too. this will let you move the tensioner.
on some of the 3800 gm engines, you'll need to take out the motor mount that goes through the belt. sometimes you can remove just the bolt that goes between the belt and take out the spacer it goes through between the mount and the engine. you'll have to bevel a corner of this spacer to get the thing back in place.
if you need to take the mount out completely, you'll need to jack up the engine at the oil pan quite a bit, and take out both pieces of the mount.
I know this is a bunch to take in, but once you get the old belt off the pullies and see where the mount goes through it (if one does) you'll quickly understand what i've said.
plan on spending the better part of a day on this.

I`m pretty sure your belt tensioner pully is just held on with a couple bolts.Remove your serpentine belt,your main belt.look at the pulley see where the bolts are that hold it on and remove them.They are spring loaded so when u take it off make sure you have the new one to put on because once you remove it ,it is no good and have to put the new one on.
the main digram for all drive belt ( flat belt ) is . first look to all pully make drowing out side with small paper 3 or 4 or 5 or 6 .....pully the main drive pully is crank . the end of you belt round the pully must be more than 180?? angl. alternator angl. more than 180 .compressor or water pump anther pully try use same digram .guide pully and belt tensioner no need to put angl .
ok I do not know what the cofigure is on your jeep but let me explain how it works and then you may be able to put it on. First look at the pulleys and see witch ones are smooth and witch ones have lines. smooth pulleys match to the smooth side of the belt ridgid side matches with ridgid side of belt. next I will tell you a rule to most serentine belts. Your crankshaft pully is the main drive so the belt will rap around almost 3/4ths the way around the pulley. All driven pulleys witch are the ones the run the water pump, altenator, compresor, and power steering rap around 3/5ths around the pulleys then you have the tentioner witch will apply pressure down on the belt so make shure the belt is under the pressure side. You can put a 3/8th ratchet in the tentioner to move it. if you still have pulleys that I have not covered they are their to complete the right amount of rap on the driven pulleys. The main thing to look at is if its smooth then put the smooth side of the belt on that pulley. If this did not help just coment back and I can get the book out tommorrow when I go to the shop and email you a copy of the diagram
What is needed Tools: 6mm and 8mm allen wrench socket, 5mm allen wrench.
8mm, 13mm, 19mm socket and ratchet. 10mm combination wrench. Long
ratchet extensions (at least one 6in, more are helpful). 5inch Wheel
puller (for main shaft pulley). (Some models may need a special spanner
tool to adjust the timing belt tensioner) Parts: 2 gal of anti-freeze
mixed with distilled water. All three V-belts. (Alt, A/C, P/S) $32.95
New water pump top. $91.91 New gasket for WP. $9.13 New timing belt.
Remove battery cable (either power (+) or ground (-)) remove
alternator remove A/C remove power steering pump .Remove water pump pulleys remove
main shaft pulleys remove timing belt covers remove A/C mounting
(don't turn any of the wheels its connected to) replace timing belt
water pump face put on new gasket and new part.
Leave pulleys off.
replace bottom timing belt cover, replace crank shaft pulley, replace steering
pump, replace A/C, put small belt on A/C (hang loose) put large belt
around A/C, Main and water pump pulley. put middle size belt on Main water
pump and power steering pump reattach bolts for the steering pump
pulleys put alternator back on adjust all belts. connect battery
areas: Main pulley: There are 4 6mm hex head bolts. These must be
removed. The main 19mm hex head can be used to turn the engine it the timing belt
slips and you have to readjust the timing.
Putting on new
belts: This can be a real pain if you get VW belts. The adjustments won't
give enough to put the belts over the edge so the easy way is to remove
the pulley on the water pump. Then its real easy.
If you turn the wheels that the timing belt goes on you will
have to reset the timing. Mark the timing points with something
like whiteout so its easy to see. The timing mark on the toothed
gears are small dots. The timing mark for the crankshaft is a small cut
on the outer pulley. When its aligned with the intermediate wheel timing
mark (there is an arrow on the cover as a hint) should intersect as viewed
from the right wheel well. The camshaft timing mark should line up
with the top of the engine near the front.
Power steering pump: It is
held on with lots of bolts. One is in a channel that is hard to see but
can be found with a 6" extension. If you look at the pump you will see
three bolts that go into the housing. This should give you an idea where
the forth is.
To put a serpentine belt back on your car, you should jack the right side up, and remove the tire first. Remove the plastic cover behind that to gain access to the side of the motor with the pulleys on it. On the side of the motor you will see down low the belt tensioner pulley witch swivels with the use of a wrench, i think it is a 14 or 15 mm wrench which is needed. Put the belt around all the other pulleys in the format they go by the picture under the hood, saving the last part of the belt to go the tensioner.Swivel the tensioner and but the belt over it, and put everything back on in reverse order.
remove the belt to ac compressor.take your serpentine belt go around crank pulley goes around power steering pump goes around alternator and the tensioner on the far left. the water pump on the out side and the top idler pulley out side. the belt drives them from the out side. then you put your ac compressor belt back on.
