serpentine belt

How do you replace the belt?
I thought 1 of the pullies would be spring loaded.

Under the PS pump is a tensioner bolt. All you gotta do is loosen that up and it loosens the belt.

Mine was seized so I had to remove the PS pump completely...but it was ok because my PS pump was shot as well.

All the belt adjustment bolts are located on the power steering pump assembly. The very top bolt must be loosened, then on the back of the assembly, you'll see two bolts sitting in holes that are slotted - both of these need to be loosened. Now on the front again, look just below the steering pump pulley and you'll see (or feel) a bolt there, this also must be loosened. Finally, on the side, at the bottom of the assembly, you'll see a bolt head - this is the adjustment bolt, and is about 3 or 4 inches long. Have a look at this and see if the threads are clean and spray it with a bunch of penetrating oil - now you're ready to start turning. All the bolts I described have a 1/2" head and I use a 1/2" wrench or gear wrench for all but the adjustment bolt, and for that I use a 13 mm socket, just to give me a bit of slop to make it easier to put the socket onto a rusted bolt head. Turn the adjustment bolt counter clockwise to loosen, but watch how hard it is to turn, you may need to go back and forth a few times to get past any accumulated rust, otherwise you're likely to break the bolt - add oil as you turn it back and forth a few times.

You need to remove the air box completely to get to the adjustment bolt and the bottom bolt on the front (this bottom bolt is a lock bolt for the adjuster.

When you're done, don't forget to tighten ALL the bolts again, otherwise the pump can get pulled askew.

Before you dive in... not all YJ Jeeps have the adjustment in the P/S pump.

If you have A/C your belt tensioner may be on the Alternator instead of the P/S pump.

I just replaced my belt before I hit some trails this past Tuesday and used a Gatorback belt. The instructions above by Alfons are very good. I actually just unbolted my PS pump and went that route because I didn't even see the adjustment bolt. All said it took me around 10-15 minutes to do this. One of the easier jobs on a Jeep like changing fluids and plugs. I know I have a belt diagram on my 95 with AC right under the hood on the fan shroud. I don't know if a 94's belt routing is any different but I'll post a pic regardless.

Several photos. The various fasteners are difficult to get a clear shot of. This is a shot from the front, directly above the PS pulley and the belt, looking down. You can see the tensioner bolt threads horizontally across the middle of the photo. The bolt head you see must be loosened to allow the "slide" on the tensioner bolt to move.



Here is a shot of the tensioner from under the Jeep, looking up and forwards. The black hose to left is the low pressure line from the PS pump, you can see the lower part of the curve of the PS pump pulley in front of the tensioner bolt.



This next photo is a closeup of the tensioner bolt threads, and the slide thingey, you can see just a wee bit of the lockbolt head above, "behind," and to the left of the slide as this photo is taken from under the Jeep looking forwards just as in the last photo in this reply sequence.



Finally, some specs on the tensioner bolt itself.



I seem to recall that you also have to loosen the bolts holding in the PS pump to allow the pivoting movement that allows either loosening or tightening to take place. Once new belt is on, you can make them all finger tight, then tighten the tensioner bolt to the desired tension, tighten down the lock bolt, then final torque the other bolts holding your PS pump to its mounting points.

Give me a few moments while I go back outside and put it all back together......

It would help if you list which engine you're refering to. The serp on the 4.2 is both adjusted and routed different than the 4.0.

timatoe--we're currently answering the question posed by jetchey321 25 April 09 who has a 94 with a 4.0 The OP of this thread posted up the original question in Aug '08, and it was "thread resurrected." Thanks for chipping in though.....I don't have a clue about things on the 4.2 yet.

I usually catch the old thread thing and didn't even see the second question......

It got me also Tim. I was wondering why a guy with a CJ7 was asking the question. Actually jetchey321 has a 2.5L which is adjusted from the power steering pump.

Sorry to hijack this a bit, but I have the same motor and I need to change my belt. I think that I found the tensioner bolt but when I loosen it it does nothing.

Does anyone have pictures that aren't so close up as the ones a couple of posts ago?
