Sorry, with or without power steering ? Have look at this link.Scroll down to find yours, then click on picture to expand/explode for better view if needed. If it's got the idler pulley, you'll have to get a wrench on it and relieve tension, while putting belt back on. Careful, make sure wrench is all way on bolt.

using a breaker bar or some other tool w/ 1/2'' drive, insert into idler, there is a square hole, remove belt tension, donot remove belt, but lift belt off say the alternator, it would help if you hang the belt w/ wire or something so as not to let it drop. using a 15mm wrench, remove mounting bolt to idler, remove idler. better to replace the entire ilder w/ pulley, as an assymbly, they wear out like any thing else. when istalling new idler, must be positioned correctly. theres a finger which protrudes out of idler, this must be inserted @ engine sideof idler. reinstall bolt, tighten, reposition belt, using breaker bar 1/2" drive again, remove belt tension, so you can get belt over alternator pulley, release tension , done ! make sure belt is centered, and on properly according to belt rounting. when satisfied w/installation , start engine, check your work, remember to visulize existing idler, etc., etc., before you start this so you can put on the new one on exactly the way the old one was !!!!!!!!!!1

  1. Loosen the adjusting arm and pivot bolts.
  2. Turn the alternator belt adjusting screw counterclockwise until the old belt can be removed.
  3. Remove the belt.

To install:
  1. Install the new belt over the pulleys. Check that all the V-grooves make proper contact with the pulleys.
  2. Adjust the belt tension, then tighten the adjusting arm and pivot bolts.

See Figure 2
  1. Loosen the nut in the center of the idler pulley.
  2. Loosen the idler adjusting screw until the old belt can be removed, then remove the belt.

To install:
  1. Install the new belt over the pulleys in proper contact with the pulleys.
  2. Adjust the new belt to specifications as follows: Turn the idler pulley nut to the right to tighten the belt to a specification of 220-265 lbs. (980-1180 N). Torque the idler pulley nut to 25-37 ft. lbs. (34-50 Nm).

POWER STEERING AND AIR CONDITIONING BELT
See Figure 2
  1. Remove the alternator belt.
  2. Loosen the nut on the tensioner pulley.
  3. Turn the belt adjusting screw on the tensioner counterclockwise until the belt can be removed, then remove the belt.

To install:
  1. Position the new belt over the proper pulleys, making sure the V-grooves are properly seated.
  2. Install the alternator belt.
  3. Adjust the power steering and air conditioning belt to a specification of 154-198 lbs. (690-980 N) with a belt tension gauge.
  4. Adjust the alternator belt.
3.0L Engine (Except SHO) and 3.8L Engine
VEHICLES THROUGH 1993 WITH AUTOMATIC TENSIONER

See Figures 4 and 5
  1. Insert a 1 / 2 in. breaker bar into the square hole in the tensioner.

On the 3.8L engine, the tensioner has a1/2in. square hole cast into the rear of the tension arm directly behind the pulley. On the 3.0L engine, the1/2in. square hole is cast into the spring housing on the front of the tensioner.
  1. Rotate the tensioner clockwise and remove the belt.

Fig. Fig. 5: 3.8L belt schematic-1993 shown


To install:

  1. Install the drive belt over all the pulleys, except for the alternator pulley on the 3.0L engine for vehicles through 1992, or the idler pulley for 1993 3.0L vehicles.
  2. Rotate tensioner counterclockwise and install the belt over the alternator pulley. Make sure that all the V-grooves make proper contact with the pulleys.
  3. On the 3.0L engine, install the alternator belt for vehicles through 1992.
  4. For 1993 3.0L vehicles, install the drive belt over the idler pulley.

Belt replace


You will see pulleys on the engine. The pulley with nothing behind it is an idler pulley. All the other pulleys have a water pump, A/C pump, steering pump, and alternator.

The idler pulley puts tension on the belt. It has a fitting for a socket drive, either 3/8 or 1/2. You are to insert a rachet or socket extension in that square hole. When you push the pulley down it takes out the slack and you can slip the old belt off. Then you tread the new belt around and push the idler pulley until you get enough play to put on the new part.

Belt diagram 1997 toyota corolla? alternator belt replacement?


The 97 Corolla has three accessory belts. The alternator belt is the one you see when you look down on the passenger side standing near the front of the engine compartment. If fits over the alternator and the engine pulley. The belt beneath it is the a/c belt (if the car has a/c). It fits over the engine pulley and the a/c compressor. The power steering belt is toward the rear of the engine compartment, on the same side. It fits around the engine pulley and the power steering pump.

Replacing the alternator belt is not too difficult. Standing in front of the car and facing towards the rear, loosen the locking bolt under the right side of the alternator. Then loosen the alternator hinge bolt on top of the alternator. Now you are ready to loosen the alternator belt tensioner adjustment bolt, accessed under the alternator from the front. Turn the tensioner until the old belt is loose enough to remove, then turn it further so that the new belt will go on easily. Replace the belt and re-tension until you have about 1/4 in. to 1/8 in. of play in the belt, tighten the lock bolt and the hinge bolt, and run the engine. If the belt squeals it means you need more tension, but do not overtension. Recheck it after a few days.

How do you change a serpentine belt on a 2003 Oldsmobile Alero?


Brute force - you have to pry up the tensioner pulley. The way we did it was put the belt over the alternator and A/C compressor, and get it back in place around the main bearing pulley. Then we took a bar and forced up the tensioner and slid the belt over the main bearing pulley. Voila . . .

2 Loosen the hold-down fastener for the idler or generator pulley.
3 Pry the idler or generator pulley inward to release the belt tension and remove the belt.
4 Match the old belt up for size with the new replacement belt.
5 Observe the belt routing diagram in the engine compartment.
6 Install the new belt over each of the drive pulleys. Often the manufacturer recommends a sequence for feeding the belt around the pulleys.
7 Pry out the idler or generator pulley to put tension on the belt.
8 Pry out the idler or generator pulley to put tension on the belt.
9 Install the belt squarely in the grooves of each pulley.
10 Before adjusting belt tension, check for proper pulley alignment. This is especially critical with serpentine belts. Measure the belt deflection in its longest span. If a belt tension gauge is available, use it and compare the tension to specifications.
”If a belt is too tight, wear to bearings for the water pump, alternator, and engine crankshaft can result.”
11 Pry the idler or generator pulley to adjust the belt to specifications.
12 Tighten the idler or generator pulley fastener.
13 Start the engine and check the belt for proper operation.

I changed the altenator, but cant get the belt to go back on right. I tried putting it on the back half of the double pulley, but the car sqealed and didnt run right, but when the belt is angled funny...


If the belt is angled funny, you do not have it routed correctly.
There should be a belt routing diagram under the hood somewhere. Check that the pulley position of the new alternator is the same as the old alternator.

Why not identify your vehicle; Which model? What year? Which engine? Does it have A/C? Answering these questions will allow myself and others to give you a much better answer.
