    Thank you for your help. I have removed the two bolts and the replacement alternator has only two bolt holes in it. I cannot see any more bolts to remove. Where exactly are they located? Thanks.

My son just got the alternator off of my Trooper (1997) and he said removing the wheel is not necessary. He took off 2 bolts from the top and several from the bottom that were very difficult to remove but then the alternator came off pretty easy. He says if it loose then it should come off pretty easy, if it is not loose, you must be missing a bolt somewhere. He also says is you are in our area, call him and he will take it off for $100 =)

    There are 2 bolts for the tensioner bracket, and then there are 2 on the alternator, one of which also goes thru the tensioner bracket. He got the old one off and is now working on putting the new one on. He is pretty frustrated since he has never had an alternator take more than a couple of hours and he is almost 8 hours into this one. Good luck.

1998 Isuzu trooper 3.5 alternator replace

step one remove battery neg lug .
the above video (of book?) is wrong.
the belt tension-ing step was skipped.

remove belt steps remove alt. wiring. remove alternator (bolts) it falls free. replace it , reverse steps above belt back tension belt. battery cable back. test run. charge/BAT lamp off?
see wrench below, turn it CW.
this releases the spring tension and belt comes off
to put back, do same and put on belt and release wrench.

Have a 1997 Isuzu Trooper. The battery will not charge, has new alternator on it. Any ideas??

Check the large cable on the alternator to make sure it has 12 volts on it with the engine not running,if it does not,then this is the problem,running a new one to the positive side of the battery to this terminal on the alternator will solve the problem.

Hi im trying to change the alternator on a isuzu trooper 3.2 petrol any advice as it seems very difficult to access thanks

Ok changed one today , here we go :
It sucks get over it now!
Go to right wheel arch pull back rubber splash guard, you will see the altewrnator, oh good idea is to turn the steering all the way to the right, this gives you more space to work in the wheel well.
You will need 14mm through 11mm sockets I think and open mouth wrench's.
Disconnect the live side of the battery NOW.
Loosen the top bolt , it takes patience and a gentle pry bar but it will move .
Now looses the bottom nut and remove it , this lets the alternator hinge on the top bolt.
Get underneath the alternator and support with one hand as you undo the top bolt, it should drop a bit 1" or so.
Now disconect the bolted lead and the 3 pin connector, the alternator is free now .
Now comes the really friggin frustrating part , you need to get the alternator out of the gap in the wheel arch you initially started at.
Sorry I can't describe how , you just have to twist and turn it till you work it out , but take my word thats the only way its coming out.
Oh yeh some where in there take off the belt ( had a moment there).
If it all gets too much you can take off the bracket that is used to adjust tension , its a **** to get off and an even bigger **** to get back on , but I did it today in 103 degree heat and didn't shoot or kill anything , good day eh?
Once the alternator is out go get high or drunk , cos you've got to do the whole thing in reverse,man that blows take my word for it.
Good luck mate , I tell it how it is enjoy.

How do you replace front rotors for 1997 Isuzu Trooper

you will have to pull the calipers and everything off in order to get to them. remove center cap on rotor and remove center nut, pull out bearings. rotor bolts onto hub possibly with 14mm bolts and nuts take these loose and rotor should seperate from hub.

Alternator belt diagram 1992 Isuzu trooper

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. :-)

1997 Isuzu Trooper alternator replacement

You'll have to rock the alternator back and forth to get the bushing that the lower bolt goes through to slide back enough for the alternator to slide out.

Isuzu alternator

You probably have this sorted by now as this post is a couple of weeks old but just in case you haven't, here goes.
Remove the front belt/s. Remove radiator cowl. Access the alternator bolts by removing right front wheel. Once diconnected, push the alt up past the radiator and into the hands of your assistant.
This method is for the 3.1td engine. If you have a V6 I have been told that the alt will come out through the wheel arch which will avoid removing the belts and cowl.
Also, don't forget to disconnect your battery/s.
Good luck.
