Need to replace alternator. where is tension release for serpentine belt?

Rotate the tensioner using a 3/8 in socket driver to loosen the belt. Carefully remove the belt form any pulley. Release the tensioner and replace the belt on all pulleys except the alternator. Rotate the tensioner again and put the belt over the alternator pulley. Release the tensioner and verify the belt is properly engaging all pulleys.

make a sketch of the belt before removal, helps with refitting. if there is a belt tensioner release it , if auto tension fit a socket and pry bar to the alternator pulley nut and release tension and remove belt, disconnect battery and remove alternator bolts.

You either got the wrong parts or you need to move the tensioner just a little bit farther.

I presume the serpentine belt is in the way. First, disconnect the battery terminal. Then make sure the serpentine belt diagram is readable and remove the serpentine belt. Then release the tension on the alternator belt and remove all the bolts and wiring.

need to release the belt tensioner with the appropiate tool and take out the belt and remove the alternator.

Which engine?
To replace the drive belt or serpentine belt on a Voyager check the engine size. For 2.4L engines, a serpentine belt runs the air conditioning compressor and alternator. For 3.0L models, the alternator and power steering share a belt with a separate belt for the AC. Dodge recommends checking the belts every 15,000 miles or 12 months for possible replacement. I have gone 3 yrs with one.. it will start squealing when you turn on the heater to defrost..

Most replacement belts have a diagram on the package. However, the easiest way is to pay close attention to the belt you are taking off, and replace the new one the same way. The pulleys themselves are usually 'grooved' or 'smooth' which tells you whether the front or back of the belt is against it. The hardest part is figuring out how to release tension on the idler-pulley. If you can get the belt on and the idler/tension pulley (same thing) pulls the belt tight, chances are you got the belt right. If you don't know what I mean, then the mostest best way is to get a Clymer Manual and read up. Its really a simple thing to do yourself.

I used a long heavy duty screw driver to release the tension on a Pontiac Sunbird.. the belt will only fit on one way..

Pry the tensioner with appropiate tool, then pull the belt off the alternator pulley before releasing the tensioner. Note the routing of belt before doing this job. Make sure the new belt is same length before putting back on, reverse the procedure.

To release belt, You need breaker bar with a 15mm or 19/32" socket . There a auto tensioner to left of the alternator. Place the socket on silver color bolt and pull breaker bar to the right this will relaese the belt.

there is an 8mm bolt right under the alternator. loosen that up then loosen the bolt on the idler pulley and itll come right off

assuming it has a serpentine belt, you need to pry on the tension pulley to release the tension on the alt. A jack handle works good for this.....or a large screwdriver....
