I think it was a 15mm.. if your referring to the belt tensioner
If you have a autozone or another store that would let you rent tools- it should be be available. (I personally spent the 18bux for a serpentine belt tool.)
Other than that the whole job shouldn't take longer than 15mins.
1- serp. belt.
3-alt. bolts
1-connector..
1-bolt-on wire termination (alternator)
I'm basing all this on the 3.0L engine... unsure if the 4cyl. and the bigger 6 is similar.

Wait wait wait. If you're just trying to loosen the tensioner, you can put a 3/8 inch drive into it and push it to the bottom of the engine (I believe you'll need the socket set on loosen), and it will loosen the tension, though it's quite tight in there, I got a good little cut on my hand after getting caught on the fan shroud. Use a breaker bar or long drive.

EDIT: add on: the 4.0L is the same was as I believe 99ranger said? At least my '94 is.

I think you would be in for a serious fight to get the belt back in the path by using that method.
Also, with as much tension on the belt, who knows what kinda damage the tension force will do to the last bit of exiting thread on that idler pulley bolt, and the bearing on the idler.
It may jus' booger up a few threads but it maybe enough to be a headache to go back in.
Jus' my .02... I'd look to rent or purchase a serp. belt tool or use a method like Zach suggested.

BTW.... the tool kit Should have the "shorter" sockets and claw foots and a thin profile leverage bar to help make it in behind the fan...

My 91 4.0 tensioner has a 16mm bolt in the center of the pulley. A 5/8 socket will fit too and either one should be a six point socket to get the best bite. With a socket and breaker bar on this bolt in the center of the pulley you should be able to compress the spring tension on the belt by moving the pulley up and away from the belt and sliding the belt away from the pulley. Then bring the breaker bar back down to let the tensioner rest at the built in stop. Then remove the socket and belt to get at the alternator.
