Facing your engine from the front of your car, the alternator is on the mid left side below your ECCS/Throttle body/Intake.
There are 2 bolts you will have to loosen.
The first is the bolt on the FRONT side of your alternator tensioner. It takes a 12mm socket or wrench. This will free up the tensioning bolt that is located to the LEFT of the first bolt which you can unscrew to loosen your belt. I believe it also takes a 12mm socket. (I took off my intake tubing to get to it.)

The alternator belt on a 1993 Nissan 300ZX will typically squeal if it has excessive wear or it has become lose. This provides a good opportunity to replace the belt before it complete fails.
Not sure if the 92 is the same as the 91, but on the 91 you need to loosen the adjusting idler on the alternator on top and the a/c idler from the bottom. remove the a/c belt & install the alt. belt, make sure your route is correct between the two guide as the belt goes up to the idler... hope that helps.
The alternator is mounted on an adjustment bracket. You can loosen the lower bolt a couple turns then loosen the upper bolt a couple turns and slide the alternator forward to get the old belt off and the new belt on. Hold the alternator back with a big screwdriver or breaker bar to re-tension the new belt while you tighten the top bolt, then tighten the bottom bolt.
You need a 17mm wrench. All you need to do is rotate the tensioner pulley near the alternator and slide the new belt on. It is quite simple. I have a 1994 jetta 2.0l which I have done lots of work on, too much to list.
loosen adjuster bolts and take off belt......
loosen the bolt in the center of the drive belt pulley, then loosen the bolt on the side of the pulley. as you loosen the side bolt the tension lets up
the alternator belt is the one all the way in the back. You have to loosen the power steering pump, A/C idler pulley, and then loosen the alternator.
Loosen the alternator tensioner bolt. The alternator belt will become loose. Remove the alternator belt. Put the new alternator belt on and reverse the process.
Suggest replacing all the belts also. 1st belt, remove coolant res. loosen the pulley next to the res. then there is a tension bolt behind it. get under the car, the alternator is right there on the passenger side. possible under a small shield. loosen all the bolts on the alternator, then there is a tentioner on the alternator. loosen that, remove belt, then take out the rest of the bolts, along with the plug and the ground wire to the alternator. for the P/S belt, loosen the other pulley 14mm, and then the tention bolt is another 12mm.

The alternator slides with the alternator bracket. Loosen the bolt that goes through the bracket into the alternator. You may need to loosen the bolt on the bottom as well. Don't remove either. Then slide the alternator towards the opposing pulley to loosen the belt enough to disengage.
if the car doesn't have an automatic tensioner than if the belt is around the alternator pully you loosen the bolt holding the alternator on and move the alternator to tighten the belt.
Disconnect the battery. Loosen the alternator bolts and slide the alternator to loosen the belt. Remove any other belts in front of the bad belt if necessary to get to it. Remove the alternator belt, and install the new one. Pull the alternator to the side to tighten the new belt snug and hold while tightening the bolts. Reconnect the battery
