Fan belt diagrams

I just removed the alternator from my 2008 Yaris. The belt was squealing and thought I could put a little more tension on the belt by adjusting the alternator. I actually found the bottom mount bolt loose. I put about a 1/4 turn on it but it still wobbled. I took the bolt out and the mount hole seems elongated as is the hole on the alternator. Is this normal? If not how is it fixed.

SOURCE: squealing belt

Causes of problem like yours can be:

  1. the alignment of the pulley of your alternator and the alignment of your engine's pulley. you may check it by just looking at it, be sure they are precisely parallel with each other.
  2. The size of the opening of your pulleys, you try to measure it using a caliper, they should have the same mouth size
  3. loose pulleys causing wiggle
  4. rusts on your pulleys
Hope I helped you

Belts stretch from new. Try to tighten them again. Hopefully the are not glazed or this may stay with you.

That should be right if it is an idler pulley. On belts that do not have idler pulley you will have to loosen lock bolt on adjuster. Like alternator

SOURCE: How to loosen alternator tension on a 2003 Lancer

I have not seen this vehicle but, the center bolt or nut that holds the tensioner to the block is backed off two turns first.
Then the adustment bolt (most are accesed from under the vehicle) can be adjusted to give enough slack to install the new belt.
If this is still too tight, remove one of the two or two of the three bolts that mount the Alternator to allow for another 1/8" and install the belt.
Then remount the Alternator.
Then readjust the tension bolt.
Finish with the bolt or nut that mounts the tensionor to the block.
good luck.

My steering stiffens if i put on the air conditioner

By fan belt do you mean the serpentine belt that spins all your accessories? If so check the tension on the belt. The belt tensioner controls this. If the tension is good, then one of your accessories is likely not spinning like it should causing the belt to slow down when the ac is on, causing the power steering pump to not spin like it should. I would take the belt off, spin each component separately and see if anything is stiff.

Had my serpintine belt tighten due to squealing, now my car is making a grinding sound. There is now fluid leaking from my car can it be the water pump bearing anyway

It's extremely possible the squealing was the water pump all along. Your car has a belt tensioner that automatically keeps proper tension on the serpentine belt.Manually tightening the belt most likely put more strain on the bad water pump and the bad bearing you heard is well on it's way out.

2008 dodge ram 4x4 1500. At idle wipers slow, headlights dim and heater slows when fan is on high. Is this normal?

It shouldn't be. This would suggest that for some reason your alternator isn't performing at low speeds, especially if the problem goes away when you rev the engine up a little. I would check the connections at the alternator and battery to make sure they are tight and clean first. If you have to remove the battery cables to clean them be sure you know how to recode you radio first. That info should be in your owner's manual.
It could also be that there is not enough tension on your belt, or it could be the alternator itself. If the belt tension and alternator are both good, it should be putting out 14 Volts or a little better when the truck is idling.
You may also need to check the fan and the fan switch if everything else is good. They may be the source of the extra draw. Hope this helps.

1999 dodge durango 5.9 v8 loud squealing noise from under hood replaced tenison pulley, idler pulley, ac pulley/clutch assembley,and belt please help

You didn't mention the alternator, power steering pump, or water pump. In fact, any pulley other than the crankshaft one can have a bad bearing or dry seal. Remove the belt and spin each pulley while listening for any rough noise or squeal. If it was the crankshaft, it might be time to check the oil. Start the engine with the belt off to see if it does squeal. Make sure the noise isn't coming from the radiator fan(s).

Step by step instructions replace alternator on a 2000 Lincoln Continental

Hello, first of all disconet your battery. Then locate your alternator and remove the wiring. You will then see two bolts, one is for your fan belt adjustment, take this bolt out and dont loose it. The second bolt is much longer, this is the bolt that allows you to move your alternator back and forth so that you can tighten your fan belt. Remove this and as you pull it out hold onto yoour alternator as it will now come out. You then position new alternator sliding long bolt back in place. Do it up but not tightly at this point. Replace the smaller bolt and make sure that you put your fan belt back on. Pull the alternator tighly onto the fan belt before tightening the smaller bolt. Once the fan belt is tight you can then tighten the long bolt. Reconct your wiring, reconect you battery and you should be right to go. If theres a squealing sound when you start the car you may have to retighten your fan belt, you dont need to take any wiring off to do this. I hope this is helpfull.

How do you change the alternator belt on a 2002 toyota avalon xls

There are two bolts on the alternator:
One holds it in position on a rail to adjust belt tension and the other mounts it to a brace. Loosen both of these and angle the alternator to release the belt tension and remove the belt. Put the new one on and reverse your removal technique. You want the belt taut, but not tight. If it squeals when it's running, just adjust the tension to make it a little bit tighter.

Need belt diagram!

I found these 3000GT/Dodge Stealth DOHC Serpentine belt diagrams on the link below...

If you are re-using the drive belt, be sure to install it in the same orientation as it had before removal (same side facing the wheel well). Insert the belt from above. Turn it "sideways" to fit it in between the alternator pulley and the AC pipe. Correctly tension the drive belt using its tensioner pulley. Before installing the plastic covers and wheel, temporarily install the IC pipes and battery negative cable and start the engine to check the belt operation. If the belt squeals it is either misaligned or too loose. I found that my old belt squealed when installed "backwards" from how it was removed. It did not squeal when installed in the same orientation. If you have messed with both drive belts, spray a little water on one belt at a time to see which is squealing. A misalligned belt will stop squealing for a very short time after water is sprayed on it, but the squealing quickly comes back louder than before. If the belt is loose, the squealing will immediately get louder. Also note that there is just a little play in how the alternator bolts in. If misalignment is a problem, loosen all four bracket mounting bolts (this may require again removing an IC pipe), reposition the alternator, and tighten the bolts to see if this helps. Do not tighten the belt too much because this can lead to shaft bearing failure over time.

Here are some links concerning drive belt adjustment.
