How do you change the AC compressor on a Cutlass Supreme?
I have a 95 3.4 and it's on the passenger side of the engine,
first you have to remove the belt, best to also remove the radiator
fan, disconnect the negative side battery cable, remove the
connection to the a/c hose, remove the wire plug attached to the
condenser, then remove the 3 bolts on the flywheel side of the
compressor. you should also replace the accumulator, all the
o-rings and add 4 oz. of pag 150 a/c oil, 4 oz. in the accumulator
and 4oz in the compressor, turn the compressor 10 times. Change the
orifice which is right after the high side service plug. reconnect
everything while changing the o-rings and adding oil to them.
Vacuum pump the system for about 45 minutes, reconnect the battery
terminal. then add freon at the service plug while the ac is set
high and car is running. 37 lbs for my car. Hope this helps you and
check your service manual for your particular cutless supreme
