A/C Compressor freezing

08-17-2004, 06:21 AM
My son has a S-10, 4.3 liter where the A/C compressor clutch or bearings occasionly freeze up. By that I mean the serpentine belt rotates, but the ac pulley freezes up. It amazes me that it hasn't broken the belt so far, but surely it will soon.

My question is, can he buy or shorter belt and bypass the ac altogether, as he never uses it, or replace the ac compressor with an idler pulley per the no ac 4.3 liter configuration? He really doesn't want to put a lot of money into the truck at this point as he is in college.

when the ac compressor pulley starts making noises this is the time to replace the pulley assy. once this siezes on the ac compressor you will never get it off !

parts are available to replace the pulley bearing assy or just the bearing for the pulley.

some part stores have tools available for this replacement.
