A 1/2 inch ratchet should do the trick.
By loosening the tension on the alternator nut
go dokey
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.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
how do i find the auto tension release for the serpentine belt on a 2004solara
My alternator stopped recharging my battery but I can't take the tension off my serpentine belt to put my alternator back on.
Remove belt and tensioner should just be bolted to engine
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.
Near the top of the serpentine belt path is a belt tensioner; it is spring loaded and has a shinney pulley on it. Insert a wrench into this tensioner and pull against it and the tension will be released so you can replace your belt. I am assuming your question is about the serpentine belt.
how to release serpentine belt tensioner on 1991 C1500 Chevy Silverado?
Buy a Chevy!!!! That was a big help. Most but not all serpentine belt systems have a spring loaded tension pulley that just holds constant tension on the belt. If there is a tension pulley, it will be the one pulley that is not attached to anything like the alternator or AC. After that, the alternator is the most likely to be the one that adjusts.
Most cars now have a serpentine belt that drive the alternator, water pump, power steering unit, etc. The belt tension pulley is a spring loaded pulley that keeps the proper tension on all these units. It can be moved to release the tension in order to remove the belt.
