The ac compressor may be on its way out and binding. Disconnect it before it fills the ac system with trash.
Any air-conditioner compressor, from a 4.3 liter Chevy engine, will interchange with an air conditioner compressor from a 1997 Chevy S 10. The air conditioner compressors are identical.
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.
Check the low side pressure switch, the pigtail, the compressor clutch itself and then check to see if you still have an air gap between the hub and the clutch when the system is turned off.........
theres no such thing

It is probably worn out and about to seize. Replace it before that happens so the system doesn't fill with debris from the pump.
The compressor clutch does not need to be shimmed. The outside disc is pressed on until the proper air gap is achieved. If it is pressed on to far it has to be pulled off and reinstalled.

Could be a vacuum leak. Check the throttle body base gasket.
1997 s10 4.3 Chevy blazer. what inlet does the freon go in. the one on the aluminum tank where the hose from the compressor goes into it?
No. Air bags were introduced on the 1995 S10 Chevrolets.
Most commonly would be lack of freon.
