put a wrench on the pulley side of the tensioner (15mm?) and turn. The pulley arm will move & loosen up the belt.
If its the 3.4L it has an automatic tensioner. look right under the alternator and there is a pulley. That pulley and arm is the tensioner. To release the tension, there is a bolt on the inside of the pulley, put a wrench on it and pull like you are trying to tighten the bolt. The arm is spring loaded and will pull up, releasing tension.
This vehcile uses a serpentine belt. The belt tension is set automatically by the tensioner. If the tensioner is stuck and will not apply tension to the belt then it is defective and needs replacing.
Hey Duane==I think I use a wrench on the bolt that holds the pulley to the bracket for the idler. I think it is 13mm. Goodluck, Joe
If it has a serpentine belt it should have an automatic belt tensioner If it doesn't have a serpentine belt then alternator should be the adjustment/pivot point
The ac belt has a tensioner that is accessed from below, and takes a tensioner tool to loosen. Remove the serpentine belt, release tension on the ac belt then the belt can come off for replacement.
You can loosen the tension on your alternator belt by loosening the tensioner bolt. When the tensioner bolt is loose you can slide the alternator to the left.
how to release serpentine belt tensioner on 1991 C1500 Chevy Silverado?
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
Loosen the alternator tensioner bolt. You will be able to slide the alternator either way to adjust the tension on the belt.
The 93 Acclaim has a serpentine belt. The tensioner below the alternator is what keeps the tension. If you have not tension I would replace the belt first and then check the tensioner.
You have to use a 1/2 inch breaker bar and put it in the square hole of the tensioner and turn it to release the tension of the belt.
Should have a spring loaded belt tensioner
It should have a spring loaded automatic tensioner, if the spring is broke replace the tensioner arm assembly
the belt tensioner is mounted to the block if you are trying to change the tensioner tou have to remove the alternator.if you are trying to change the belt it is the pulley to the left of the alternator it takes a 15mm wrench which you have to pull upwards to release tension
There isn't one. The tension for the serpentine belt is an automatically spring loaded tensioner on top of the engine in the front. Place a 3/8 inch ratchet in the square slot of the tensioner arm and pull it back to releive tension on the belt. Then when you put the new belt on pull it back to get it on the pullies then release it to tension the belt.
if the car doesn't have an automatic tensioner than if the belt is around the alternator pully you loosen the bolt holding the alternator on and move the alternator to tighten the belt.
The tensioner is automatic, if it fails to tension the belt enough a new tensioner and belt should be fitted, beware it in not an easy job. Dave.
