How much oil should I put in this system. It has been flushed with a new dryer, and new compressor. The compressor has 1.5oz of oil installed. Do I need to add more?
Yes, add more. NAPA guide says that car needs a total of 8 oz of type PAG-150 oil. Ideally, drain any oil that comes in a new compressor and put all new in. The PAG will absorb moisture during storage if the ports on the compressor are not tightly sealed.
Thanks for the reply. Where can I find the NAPA guide? I also need to know how my freon this car takes.
Thanks again!
Thanks for the great info.
I have one more question. As I removed the old Compressor, I found an electrical connection on the back side of the compressor itself. The replacement compressor does not have this connection. Any idea what this connection does, and can I just bypass it?
Thanks again.
Remove the sensor from the old compressor and install in the new compressor.

I tried to remove it....but could not get it out. I think I will destroy it if I pull any harder....yes, I removed the sir clip before I pulled on it.
What does it do?
Not sure, but could be the fan switch, high pressure cutout, but clean the area well around it, spray WD40 and let it soak, then gentle rock nit until it loosens up..You need the switch,, If you break it, go to a junk yard and ask for one off of a core, as long as the color is the same.. If nothing else, try to get the electrical connector, I find it easier to get them out when clean with the electrical connector on, gives more leverage and doesn't break the plastic on the switch..but go slowly until it breaks free from the O ring..hope this helps..
Use a pick to clean out all around the switch when soaked with the WD40 or other penetrating lube.. Also lube the O ring when you install it in the new compressor..

I have already installed the compressor and charged it.....I assume if I pull the cover on the back of it to install this switch, I will loose the charge.....correct?
yes you will, it's under pressure, but you need the switch installed..

Looks to be a cooling fan switch. I would not suggest running the compressor as currently configured.
