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.

CS = Crankshaft
CA = Camshaft
IP = Injection Pump

2. Ensure timing marks aligned [10].
3. Fit timing belt in clockwise direction, starting at crankshaft sprocket.

NOTE: "ISUZU" lettering on belt should be readable from front of engine.

4. Slacken tensioner pulley bolt [9]. Push tensioner pulley against belt.
5. Ensure belt is taut between injection pump sprocket and tensioner pulley as well as crankshaft sprocket and camshaft sprocket.
6. Position tensioner lever [8] against tensioner pulley housing.
7. Remove locking bolts from sprockets [4] & [5].
8. Apply a load of 10 ... 12 kg to tensioner lever. Use spring balance [11].
9. Tighten tensioner pulley bolt to 80 Nm.
10. Turn crankshaft slowly 45 degrees anti-clockwise. Use spring balance to tension belt.
11. Repeat tensioning procedure at 45 degrees intervals for one anti-clockwise turn of the crankshaft.

NOTE: DO NOT turn crankshaft clockwise during tensioning procedure!

12. Fit tensioner lever to original position. Tighten nuts [12].
13. Install: Injection Pump flange [6], Camshaft sprocket flange [7], and water pump pulley.

Missing a tensioner for the AC drive belt? Just


Yes there is a tensioner. You will need the adjuster and the mount and the long bolt. If you goto a junk yard to get one I suggest you go to a local bearing shop and replace the bearing in the wheel.

Need to know which pulley is the tensioner pulley on a 1990 Izuzu trooper. If u can which bolt to looosen so i can get this damn belt on. HELP!


It is on the lower left - pushing against the serpentine belt to hod it in place. You need a breaker bar with a socket or large wrench that fits arount the bolt on the center. The tensioner is SPRING LOADED, and moves to the left, away fro the belt. Move the tensioner with your left hand, and take the belt off with your right (or have an assistant remove it). Re-install a new belt following the underhood routing diagram, and move the tensioner left again to allow the belt to slip in.

Need simple question answered about 1990 Izuzu Trooper.


One way you can usually tell is that the tensioner base mounts to engine with a bolt in the center of the casting, & pulley is offset from that casting. Put your wrench on the offset pulley bolt to relieve tension. There are various set-ups on that engine so maybe we better confirm which engine it is ?

Serpentine belt too tight to install


I had the same problem when trying to replace the serpentine belt on my 2001 Trooper. The Maintenance book was very vague and I couldn't tell exactly how the tension was taken off the belt, but it did clearly identify the tensioner pulley. I first removed the pulley and looked for some kind of slot that would give me the adjustment I needed, but no slotted adjustment is present on the 01 Trooper. I had to do some research so I pulled of the tensioner assembly and found that there is a spring coil which keeps tension on the belt constant, and eliminates any belt alignment problems.

The Litens style tensioner uses a spring to apply pressure towards the serpentine belt. The way to relax the spring is to use your 14mm socket and ratchet and force the pulley down by driving the pulley nut in the clockwise direction. This forces the spring to compress and the pulley to drop giving the needed clearance to get your new belt in place.

I'm attempting to replace the serpentine belt on my 2000 Isuzu Trooper, but am not able to create enough slack in the belt by loosing the tensioner to slip belt on. I don't want to pry the belt on. Any...


tensioner usually has a bolt in the center of the pulley wheel that is 17 to 19mm. use a breaker bar and socket to hold pulley back (sometimes has a lock that you can engage) then you can move the belt into and out of the pulleys.
have the new belt ready after you pull the old one, put it around all BUT the tensioner pulley and it will be MUCH easier to put on if you are by yourself>

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. :-)
