Question about 1999 Jeep Grand Cherokee
99 Jeep Cherakee Sport 4x4 Belt broke
Purchased new belt - Can't seem to find bolt/nut that I have to loosen in order to put on new belt?
It's easy and you won't need a prybar.
Hope this helps you out.

1.Most modern cars have an IDLER pulley in the fan belt train of pulleys with a heavy spring on it that keeps tension on the timing belt.
2. Get a spanner/socket and put it on the nut in the middle of the idler pulley.
3.heave on the spannner and the pulley will swing up/down out of the way realeasing tension on the belt. (depending on the tensioner setup)
4. Simply remove old belt and thread new belt on. Simple.

You'll need a 15mm, 13mm, 10mm and 8mm sockets and a 3 inch and 6 inch socket extender. You will need the same sized for regular wrenches as well.
The problem is available room. You have to take out the battery and the battery holder (15mm nuts), then remove the fan housing and then the fan (4 13mm nuts that are hard to get off if the serpantine belt is not tight) - the fan is in the way and you won't be able to get the alternator out if its inplace.
Next, you need to remove tension on the belt - this is done with a 13mm socket and wrench (access is tight on some bolts). Remove the bolt in the back of the power stearing pump assembly, then down below the pump you'll find another to loosen (don't remove). the loosen the one at the top fo the power stearing pump - you'll find a bolt under the pump where you can loosen the tension on the belt. This may be stiff and will require a 6 inch extension (the air filter and water hoses are in the way)
Once the belt is loose, you can take the 2 bolts that hold the alternator off (15mm). There is are 2 cables attached. One to an insulated post (10mm socket) and another one that is ground and some other alternator connections. the cables are attached to the block via a 13mm nut - remove this and you can pull the alternator out (I had to wedge it out with a broom handle). remove the cables, and clean the contacts on them with some 150 grit emery cloth. Pull the Alternator out and put the new one down and re-attach the cables. You'll need an 8mm socket for 2 of these nuts.
Slide the Alternator in and get the bolts in (its a tight fit on the engine).
Reassemble in the reverse order (getting the bolts back on the fan assembly took me quite a while).
Hope this helps
