Question about 1997 Isuzu Trooper
The alternator is located on the passenger side of the motor at the bottom. There is a bracket attached to the motor and the alternator. You need not take the bracket off to remove the alternator. Two bolts hold the alternator to the bracket. One bolt is on the front top of the alternator and one bolt is located on the bottom front of the alternator. The bottom front bolt is attached to the tension adjustment for the alternator. Loosen the tension screw then remove the bolt going through the tension adjustment. After you loosen the top, front bolt, the alternator should be loose enough to move side to side. Remove the top, front bolt. Now you must disconnect the alternator from the power supply. Behind the alternator is a screw with a wire attached via nut. Remove this wire. Nextly there is a series of wires with a plug on the end. It is plugged into the side of the alternator. Uplug this item. You can also access both of these from the passenger side front tire well. Something to consider is that remanufactured alternators in Rodeo's as well as the Honda Passport (which has the same engine as the Rodeo) do not work and the problem(s) associated with a bad alternator,ie; not charging, no fan blower, battery light and brake light on, still exsist after replacing alternator with reman. Use a factory original alternator if possible. It will cost a little more than a reman but will most likely save you a lot of time and headache! Hope this helps you out!!

1. Remove battery terminals and secure them away from the battery posts using nylon wire ties.
1a. Fine some comfortable eye glasses (clear or yellow) and keep them on. There are plenty of opportunities to get debris in your eyes during this procedure.
2. Spray "PB Blaster" (loosens bolts) on two bolts that secures alternator.
3. Jack-up vehicle on side to access alternator. Use a jackstand to support.
4. Using a 10mm open-ended wrench, loosen the bolt that swings the alternator. Screwing the bolt "in" or toward the engine will allow play to increase in the alternator belt. Loosen the 12mm bolt slightly next to the 10mm bolt (approximately 1.5" toward engine).
5. Continue to loosen 10mm bolt until there is enough slack in the belt to remove the belt from the alternator pulley.
6. Remove belt. It may be possible to remove belt without removing fan faring. Maybe not. If not, you will need to remove plastic fairing. If you must remove fair, go below fan fairing and disassemble connectors that hold together pieces of fan fairing. Carefully remove.
7. Install alternator fan from above.
8. Check that alternator belt is on all tracks (from below with a flashlight), and slowly tighten.
9. Secure 10mm and 12mm bolts. Recheck tightness.
10. Reassemble battery connection and run vehicle at idle for about 5 minutes. Check belt for proper tension.
11. CAREFULLY check tension of belt. Or disassemble battery connections and re-check belt tension.
12. Reassemble fan fairing (if not already assembled), re-connect battery terminals, and have a nice day. :-)
