Find the idler tensioner pulley and retract it. You then will be able to easily remove and replace the belt.
This is just a guess so take it with a grain of salt. I would buy a belt for the s10 without air conditioning and just bypass the air conditioning pump.
Loosen the tensioner pulley. The serpentine belt will become loose and can be removed. Put the new serpentine belt on and tighten the tensioner pulley.
insert a 1/2" rachet into the tension pully, pull clock wise this will relive the tension on the belt thus allowing you to remove the belt repet to install new belt. make sure the groves of the belt are properly in place before relasing the tension pully back to tension
no the serpentine belt is totally separate from timing belt
Use a half inch ratchet.Place the stub on ratchet into slot located on idler pulley and push down to relieve tension on belt. replace belt and push down on ratchet to reload Actually, I believe it's 3/8 inch and a breaker bar works just as well.
It is a idler pulley.
If it's like my 93 S10 Blazer, then you use a wrench or 3/8 ratchet fitting to release the tensioner.
It is the unit in the top right corner of the serpentine belt path.
UNDER THE HOOD THERE WILL BE A DIAGRAM
you have to loose the belt in order to slide it out by releasing tension on the tensioner pulley ,what you do it`s sore of a tight motion clockwise on the tensioner bolt it`ll loosen the belt and then you can slide it out, to install it do the same.
The diagram is on the radiator fan shroud.
if it has never been replaced consider your self lucky you've gotten some goo years out of it. if this is a repetive problem, start looking for abraisions on the pullyes or a pulley that is out of allignment with the others
