For a 94 Jeep grand cherokee, the tension is controlled through a long bolt on the power steering bracket. The bolt is about 6 inches long, located underneath the power steering on the driver side. Lossen the lockbolt holding it in place, as well as the Power steering attach bolts, and turn the long bolt to tighten/loosen. I believe these are all 13 mm bolts.

the 4.0 didn't come with a spring type tensioner if look under the p/s pump there is a jack bolt hooked to a idler pully loosen nut on front of pully and lossen up the jack bolt till you can get the belt off

The serpentine belt tensioner / pulley is on the front of the engine, and part of the belt 'routing'.

Its job is to put tension on the belt as it drives the other devices like the power steering pump, water pump, air conditioning compressor.

It is an aluminum casting that mounts with a single bolt to the engine. The pulley is attached to the arm.

There are a few ways to move / pry the arm inwards, thus releasing the tension on the belt for removing/installing: grab on the pulley bolt (15mm?) with a wrench, or some later models have an opening for a 3/8th socket wrench to attach to directly without a socket.

here is step by step instruction on how to replace you alternator. please do not forget to rate and comment abotu your experience with fixya today 3.8L (VIN 1) Supercharged Engines

   1. Position the alternator in the vehicle and secure with the mounting nut and bolt. Tighten to 5 ft. lbs. (8 Nm).
      
   2. Install the remaining mounting bolt and tighten to 5 ft. lbs. (8 Nm).
      
   3. Attach the alternator connections. Tighten the output terminal nut to 66 inch lbs. (7.5 Nm).
      
   4. Install the serpentine drive belt.
      
   5. Connect the negative battery cable.
      

3.8L (VIN 3, C & L) Engines

1. Disconnect the negative battery cable.
   
2. Using a suitable breaker bar or ratchet, rotate the tensioner counterclockwise, then remove the serpentine drive belt. For more information regarding serpentine drive belt removal, please refer to Section 1 of this manual.
   
3. If necessary, remove the fuel rail cover.
   
4. While supporting the alternator, remove the mounting bolts.
   
5. Tilt the alternator forward, then label and detach the electrical connectors.
   
6. Remove the alternator from the vehicle.
   
7. To install:
   
   1. Support the alternator in position, then install the alternator.
      
   2. Install the mounting bolts and tighten to 1 ft. lbs. (11 Nm).
      
   3. Attach the electrical connectors at the back of the alternator. Tighten the alternator output terminal nut to 93 inch lbs. (10.5 Nm) for 1987-92 vehicles, or to 66 inch lbs. (7.5 Nm) for 1993-94 vehicles.
      
   4. If removed, install the fuel rail cover.
      
   5. Install the serpentine drive belt and rotate the tensioner into position.
      
   6. Connect the negative battery cable.
      

First note the route of the belt. make a drawing.
Adjustments are made by moving the power steering pump. far right of belt system.
loosen top fixed bolt above center of drive wheel on p/s pump.
loosen bolt below drive wheel on p/s pump.
Push p/s pump to the left to loosen belt.
Remove old belt .replace following route of your drawing.
move p/s pump to right .
top of belt should have 1/2 inch deflection.
tighten bolts
The end

If you dont have belt route mail me at
[email protected]
for drawing

Good luck .Andy Bartolo

There should be a square big enough to fit a 3/8" drive ratchet into on the tensioner (should be closest to the pulley), insert the ratchet into that square, then try turning the tensioner, this should release the pressure on the serpentine belt. Hope this helps.

You mean the serpentine belt . Do you ? If thats what you mean, the tensioner is a component that has a bolt at the middle which when lossened with a wrench will lossen the tension on the serpentine belt it has a spring and can be moved . if it was a seperate belt it woud have a bolt and a brace with a U shaped hole in the middle. You would lossen the bolt and pull on the belt and it lossens up.

Hi
It's not as bad as it looks, it's only one bolt that you need to loosen and pull with a braker bar and replace the belt. Email me wit the car make and model and I will send you instructions.
