What viscosity PAG oil does our system take?
About a week ago a bolt/rock/something jumped up and made friends with my A/C condenser. Simple enough to change it, but my question is how much of what viscosity PAG oil do I add when I install the condenser? I have no idea how much I lost when it got punctured, but it's down at the bottom drivers side so I guess a lot? The A/C guy at my shop says to add 4 oz., but the Haynes Ion manual says ".75 oz of the correct oil, or as much as came out" so that's almost no help at all. Can anyone give me a hint?
Edit: Seems like PAG 150 is pretty standard on GM A/C systems. Now my only question is quantity. They say add the .75 oz, but that's assuming the system was discharged properly. Last thing I want to do is roast a compressor because I blew 3 oz out the puncture and put back less than 1/3.
