Sure if you got a smaller belt that fit perfectly after bypassing the A/C. Just disconnect, or pull the fuse to the A/C and allow it to act as a idler.
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.
Find the idler tensioner pulley and retract it. You then will be able to easily remove and replace the belt.
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.
Is there a way to bypass the ECM in a 1993 chevy s10 4.3 vortec
no the serpentine belt is totally separate from timing belt
It is a idler pulley.
what are you bypassing
Need to know if it is standard or automatic and why.
UNDER THE HOOD THERE WILL BE A DIAGRAM
It is the unit in the top right corner of the serpentine belt path.
The diagram is on the radiator fan shroud.
If it's like my 93 S10 Blazer, then you use a wrench or 3/8 ratchet fitting to release the tensioner.
