What is required to replace the ac compressor on a 96?

Removal of power steering res., alternator, and then the unit? or is there a way to go through the subframe?

I am just doing the compressor and belt.

thanks

 

This may help. Most compressors come with about 6 or 7 ounces of oil in them.
You need to empty out the oil that is in your old compressor and MEASURE how much came out.
Then empty out the oil from the new compressor and ONLY put in the new compressor the same amount that you got out of the old compressor which should be abou 2 to 2 1/2 ounces.
Then you have to use a vacuum pump to evacuate all the air out of the system BEFORE you can add the appropriate amount of freon.

Instead of buying a new compressor, you can also use the clutch reshimming method that Tech posted in the stickies.

 

And this is the post:

Before you do anything to the A/C, make sure that the system is absolutely empty of refrigerant, or you can get frost bite.

Not too long ago, a gentleman by the name of Psaboic had removed his compressor. I believe it had to be lifted up, means the PWS pump & alternator may have to get out of the way, but double check to avoid unnecessary removals.

I wouldn't recommend draining/adding oil to a new/rebuilt compressor, if you decide to get one. I would just install the components and then have a shop do the evacuation & recharge with R134a. When a shop does recharge, the R134a should contain PAG oil mixed in it. Also, some shops use R134a with tracer dye in it, so that the leak shows up under black light. If it were my car, I would replace the receiver/dryer unit as well.

Good luck,

as far as shimmy goes i dont know if that would fix my problem:

the bearing is gone in the pulley wheel, and so it doesn't turn and eats through serpentine belts

 

I see, in that case you can either buy a rebuilt compressor or find a used one at a junk yard and replace the electro-magnetic clutch. Replacing it would probably be better, as you can never tell the condition of used parts.

You can remove the compressor from under the car.

Once you remove the dryer the compressor will just slide out of that hole.

All of the screws can be loosened from under the car. Just a little hard but can be done.

I always pull the inner fender liner from close to the body by the crank pulley to gain access to the front screws by the engine. Once the inner liner is pulled back you can use a swivel and socket to loosen the screws.

 

I would take Tech's advice and try to go from under the car. I took one out from the top and while it came out, it was a major pain in the.......
