I just did this on my '99 Honda Accord EX so assuming it's the same as a 2000... put a wrench on the 14mm hex head bolt on the tensioner pulley and turn counter clock wise, this rotates the tensioner releasing tension on the belt . I found it easiest to have someone under the car pulling the belt off the bottom pulley (crank) while someone releases the tension.
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.
If it is a serpentine belt, the tension is automatically adjusted by the tension idler. If the belt is loose then the tensioner needs replacing. If it is a normal drive belt, then the alternator is mounted on a slotted bracket that allows you to adjust the position of the alternator. You can loosen the bolts and adjust the tension on the belt.
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.
Not enough belt tension.
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.
A 1/2 inch ratchet should do the trick.
