You will need ratchet and socket set, something to help hold the alt.(alternator) when tightening the belt ( like a pry bar). Loosen the bolts around the alt.. now it will move, and you need that prying tool now. use it to move the alt. so the belt has about an eighth of an inch of play. holding it there, tighten the bolts back (nice and snug). Never over tighten the bolts, they can snap on you. now start the car, and you should see the belt is not slipping any more. This job will take you about 20 to 30 minutes.

My 1992 Subaru Loyal 4 door sedan has 2 belts one goes to the alternator. How do you tighten the other one? Belt screeches badly.


the other belt probably goes to the air condition compressor, power steering and water pump. There will be probably an adjustable idler pulley that the belt runs around. adjust that pulley or if you are not familiar with the procedure then take it to an accredited shop that will do it for you

I followed the serpinetine belt routing diagram for 1994 lincon mark VIII that was on the hood and double checked to make sure it was the right belt and the belt is coming forward off the pulleys.


Then it is too loose. Double check but I'm pretty sure your adjustment is on the Alternator bracket. You loosen the bottom bolt which allows it to picot on the bracket, then loosen the upper bracket bolt and pull it outward to tighten it, lock the bolts back down and it should resolve your problem. If you have a spring loaded assembly that applies tension and you have to release to get the belt on and off then you may need to replace that or your not getting the belt all the way on. If even one of those channels on that belt don't line up properly the belt will work itself off. If you have a frozen or damaged pulley it will do this as well.

There are 3 belts on the truck. The belt that goes around the alternator is not spinning. What could cause this belt not to turn?


Assuming that the belt is not broken ... you need to tighten the belt. This one is not as easy as the other two which have tensioners. This belt is tensioned by the alternator itself. I've found adjusting it to not be a lot of fun ... the tricky part is loosening the bolt that the alternator pivots on. There isn't a lot of room and I find one of the small palm ratchets to be helpful. So to tighten, you'd loosen the upper bolt that actually holds the tension on the belt, loosen the bolt that the alternator pivots on, re-tension the belt (using something to pry on the alternator if necessary) and tighten the two bolts again. If you have to replace the belt you'll need to remove the outer two to get to this one. The outer two tensioners are adjusted by loosening the bolt that holds the tensioner pulley in place and then turning the tensioner bolt itself to tighten or loosen the belt(s)... then retighten the bolt holding the pulley.

How to change alternator belt


914d651.gif
alternator and air conditioning compressor
  1. Disconnect the negative battery cable.
  2. Loosen the idler pulley bolt.


The replacement of the inner belt on multi-belted engines may require the removal of the outer belts.
To replace a drive belt, loosen the adjusting and mounting bolts of the component which the belt is driving. Move the component inward to relieve the tension on the drive belt.
Slip the belt off the component pulley and match the new belt with the old belt for length and width. The old belt will be slightly longer. After a new belt is installed correctly, adjust the tension.
  1. Turn the adjustment bolt at the top of the idler pulley bracket. Clockwise rotation will tighten the belt; counterclockwise will loosen it.
  2. Keep the idler pulley bolt snug (but not tight) while adjusting belt tension. The adjustment bolt should turn with moderate force.

After adjustment is satisfactory, tighten the idler pulley bolt, and then tighten the adjustment bolt.


Reconnect the negative battery cable.

When replacing more than 1 belt, it is a good idea to make note or mark what belt goes around what pulley; this will make installation easier if you mix up the belts.

How do i remove the power steering belt from an 84 olds omega?


There is a serpinetine belt that goes around the p/s pump and the pulley and alternator. Ther are 2 bolts on the alternator one long that holds the alternator onto the vehicle and one short that adjusts the belts to tighten and loosen. Loosen both bolts, this allows the alternator to tilt letting you remove belt. Hope this helps. Good Luck

The pulley for the alternator belt broke and snapped the belt as well, now the car will not even start. what needs to be done and what are the estimated costs associated with the repairs


A belt is usually $15, and a pulley around $50.
If this has separate belts (not a serpentine) usually the belt goes around the alternator and off the main flywheel and there isn't and idler pulley - but I dont' know about TL's.
Basically you loop the belts over the pulleys. Something has to move to allow you to adjust the tension. Usually there is bolt on the alternator that is in a slot, so you move the alternator towards the flywheel to put the belt on, and away to tighten it up (you want a little deflection, but if it is too loose it will squeal - which is better than over-tightening).

Morning replaceing alternator belt the long one for a mitibushi 2001 gallant. its the belt that goes around all the pullys. we get the belt on but how to tighten it up once in place.


Their should ba a tensioner pully that it goes around. this part keeps tension on at all times. It is possible that you have the wrong belt or you have the belt routed wrong. Check with your local auto parts store, they should be able to give you the belt routing and the right belt if you have the wrong one.

Please contact me if your problem presists.

Thanks, Charlie1221
