Place a 3/8 drive racthet in the square itting on the tensioner assembly - push to the left (towards passenger compartment). The serpentine belt is now loose and can be removed. To remove the tensioner - loosen the retaining bolt located in the center of the tensioner mount assembly - use a 15 mm socket turn CCW - until it comes out .. When re-installing take notice of the PIN and the SLOT on the mount against the Engine - the pin fits into the slot.. I found that my rachet head would not fit into the narrow space. I used the 3/8" breaker bar that came with socket set that I rarely use. I also used a piece of 3/4" copper pipe (or whatever fits over the handle) to leverage the tensioner easier and allow my free hand to work the belt off the alternator.
Use penetrating oil and correct size wrench.
there should be a tensioner pully. Put the 3/8 ratchet in the center of it and turn.
Remove surpentine belt,then take out bolt that goes through tensioner to engine.
by loosening the belt tensioner
To loosen the serpentine belt tensioner on a 1993 Chevy Silverado, you'll need to use a wrench or ratchet on the tensioner bolt. Turn the tensioner counterclockwise to relieve tension on the belt. Once the tension is relieved, you can remove the serpentine belt from the pulleys. Make sure to note the belt routing for reinstallation.
It has a serpentine belt and has a self adjusting tensioner.
I have a 3.1L and there is just 1 screw that holds the tensioner in place.
below the alternator. there is a diagram on the engine above the serpentine belt
There is no way to adjust the belt tensioner, if it's not keeping enough tension on the belt the complete tensioner itself will need replaced.
There is a tensioning pulley that you can move to loosen the belt. Look at the belt diagram in the engine compartment to locate it.
where is the tensioner of 2002 3.1 l Chevy Malibu to adjust so that i can remove the belt when replacing the alternator?
To get the belt off, you have to put a breaker bar into the square hole in the tensioner, and either pull up or down. The tensioner spring is what tighten's the belt. It is just three bolts then to get the tensioner off.
