Usually you can loosen the tension on the belt by moving the alternator. To do this, you need to loosen the bolts securing the alternator. It usually only has two, a pivot bolt and another bolt that slides along a track. You don't need to completely remove either bolt. Simply loosen the both of them, and the alternator will pivot towards the inside of the belt, allowing you to take it off. Put the new belt on pull the alternator towards the outside of the belt until it is tight, tighten the slider bolt, and then tighten the pivot bolt, and you're all set!

If the vehicle has one belt for everything (serpentine belt). This vehicle more than likely has a center tension pulley with a bolt or nut on the front. Place a boxed wrench on this and try tightening it. It will more than likely move releasing the tension on the belt where it can be entirely removed. It will be spring loaded so you will have to hold with one hand and remove with the other. Most vehicles also usually have a belt route sticker which will help if you forget just how it was routed.

Disconnect the 1982 Regal alternator. Loosen the alternator bolts and slide to release belt tension. Put new belt on ( you may have to remove other belts to gain access) and pull the alternator sideways to put medium tension on the belt while tightening the bolts. Reconnect the battery.

loosen the tension on the belt with the tension pulley, remove the belt then disconnect your wires from the alternator then take the 3-4 bolts, holding the alternator on, off. then do the opposite to put the new one back on

Loosen the alternator tensioner bolt. The alternator belt will become loose. Remove the alternator belt. Put the new alternator belt on and reverse the process.

Loosen the tensioner pulley. The alternator belt will come loose. Remove the alternator belt. Put the new alternator belt on and tighten the tensioner pulley.

Put you car on jack stands, remove the right wheel. Loosen the tension pulley for the accessory belt (AC, alternator). Remove the belt. Loosen the tension pulley for the power steering, remove the belt. Install a new belt, and set proper tension. If you do not have a tool to measure tension, use rule of thumb. When the belt is under proper tension you should be able to twist only 3/4 of full twist. Do the same for the accessory belt.

Loosen the tensioner bolt on your alternator. Slide the alternator to the left. Remove the alternator belt. Put the new alternator belt on and tighten the tensioner bolt.

I know that on the E30's (until 1991) the alternator has a mounting bolt that controls tension on the belt. (1)Just loosen that bolt and the rest is a breeze. (2) Move the alternator in to remove the old belt. (3) Put the new one on. (4) Use a bar or large wrench as a lever to move the alternator out and to put tension on the belt. (5) Hold it there while tightening the mounting bolt. (6) Wash your hands 'cause you're done.

Simple... See how and where the old one is and put it the same way... All you have to do is loosen the belt by loosening the belt tensioner. Then unplug the cable, remove the bolts that hold the alternator. Replace it with the new one, plug it in, put the belt on and tighten the tensioner to give the belt "tension" obviously. and Presto

put a wrench on the pulley side of the tensioner (15mm?) and turn. The pulley arm will move & loosen up the belt.

You will need to loosen the alternator belt with the tensioner pulley. When the tensioner pulley is loose the alternator belt will become loose. Put the new alternator belt on and tighten the tensioner pulley.

You will need to loosen the tensioner pulley. Put the alternator belt on. Push the tensioner pulley to the left until the alternator belt is tight. Tighten down the tensioner pulley.

loosen the nut on the idler pulley. There is a bolt at 10:00 o'clock from the pulley. Loosen this bolt until you can put the belt on then tighten the bolt till the belt is tight then tighten the nut on the idler pulley. Recheck the belt tension after a day or so..

Just loosen the two bolts holding the alternator in place, take out the old belt, put the new belt in and tight so that there is a half-inch or a little slack when you push on the belt with a screwdriver handle etc. You may need a crowbar for getting the right tension on the belt before you re- tighten the bolts.

First you will want to loosen the alternator. To do this you will need to loosen the bolt holding adjustment bolt in place. This is right under the alternator. After loosening this bolt, you can use the adjusting bolt to loosen the alternator and the belt should slide right off. Then you can put on the new belt and tighten the alternator using the adjusting bolt. After the belt is to the proper tightness, tighten the bolt directly underneath the alternator to keep the belt tight and from becoming loose.

Loosen the bolts on the alternator (do not take them all the way out), push the alternator toward the engine a little, take off the belt, (make sure you draw the path of the belt first) install the new belt according to the serpentine belt path diagram, and pull the alternator away from the engine (you may need a iron bar to help you be careful not to damage the alternator) and have someone else tighten the bolts of the alternator while you put tension on the alternator to tighten the belt.

Well you have to loosen up the belt by putting a socket and awrench on the tensioner and pull to release the tension of the belt. Then remove the cerp belt. Then there are two long bolts on the alternator remove them and the two wires and boom its out then repeat these steps backwords to put the new one on

When i change mine, i first disconnect the negative battery terminal for safety, then i loosen the tension bar that is connected to the alternator, keep in mind exactly how the belt goes around the alternator, water pump, power steering, etc, then take the old belt off. Then put on the new belt exactly the way the old belt hugged the pulleys, and then tighten the alternator tension bar, a good way to know how much tension to the apply is by noticing the light/clean area on the tension screw itself, that's where the tension nut sat at since factory installation.

you can put a wrench or a socket on the tension pulley, releasing the pressure on the belt.

tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done tighten it this can be done by the alternator there wil be one bot whihch will allow the alt to move loosen the bolt the put the alt under tension and tight the bolt up job done

Loosen the alternator and push the alternator down and pull the belt off, put new belt over crank and water pump pulleys and around alternator pulley and pull up on the alternator to where the belt is tight and tighten the alternator bolts down.

This was hard to do on my 86 2.5L 4 cylinder because in order to put the new alternator belt on... you have to get the other belt off... first what you have to do is loosen up the 2 pivot bolts on the AC compressor from underneath the car.. mine were pretty stubborn but i eventually got em to budge... once you can move the AC, remove the crank/water pump/AC belt. then loosen up the alternator pivot bolt located on the underside of the alternator...(this can be done from either top or bottom) once you can move the alternator.. slip the belt onto the alternator pulley and around the water pump and crank. then tighten the alternator pivot bolts while putting as much possible tension onto the belt and re-tighten alternator into place. then put or replace crank/water pump/AC belt and re-tighten the AC while putting as much possible tension on the belt by pushing the AC forward with a pry bar or screwdriver. good luck

My alternator stopped recharging my battery but I can't take the tension off my serpentine belt to put my alternator back on.
