Serpentine belt too tight to install

I'm attempting to replace the serpentine belt on my 2000 Isuzu Trooper, and even after loosening the tensioner, it is way too tight to install. I've confirmed that it is the right belt. Should I attempt to loosen the entire tensioner assembly, or attempt to pry the belt over the idler pulley to complete the 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.

Make sure you have loosened the tension bolt ENTIRELY. They can go REALLY loose so you can easily install the belt. You should be able to see how much more you can loosen it by looking at the backside of the bolt. If you were to remove the pulley and the same tension is on the belt, you will have the same trouble getting your tensionor back on and you risk stripping the threads by tightening the bolt at an indirect angle.

What tool do I need to replace serpentine belt on a 98 isuzu trooper?


This is no job for a novice. Take it to somebody that knows about these. NOT a simple job. You will need to replace water pump and tensioner also. http://www.youtube.com/watch?v=kjhNOVl1Tcc

Squeeling when starting.lasts about 30 sec.has 2 belts 1 small w/tensioner,1 lg serpentine can't find tensioner for it. where is it ?


Sounds like your serpentine belt has become stretched over time and needs to be replaced. One of the pulleys is going to be spring loaded and placing a wrench on it and pushing or pulling(gently but firmly) will give you the direction to loosen it off. This belt tensioner is non adjustable .It either tightens the belt enough or it doesn't hence the squeal.Good luck.

How to replace serpentine belt on 2000 saturn L series not ion


Click on the following direct Link. It has the Serpentine Belt Diagram for the L-Series for your specific engine and options (AC/No AC etc.). It has other additonal diagrams for your future use. It also has diagrams on how to rotate/move the Tensioner Pulley/Arm to loosen and remove the Belt.

Standard Rules to Removal the Serpentine Belt:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT OR OPENING (3/8ths or 1/2 inch square opening) rotating it\moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.

Standard Rules for Installing the Serpentine Belt:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.

b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them.


Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

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. :-)
