Hi All,

I am in the middle of putting my truck back together after rebuilding the engine and decided to install a new A/C system switching it from R-12 to R134a at the same time.

The compressor came pre-oiled w/.8oz of PAG46 oil; what is the easiest/best way to get the system going without damaging any of the new components? Keep in mind that I am starting a newly rebuilt engine at the same time, and would prefer not to spend to much time with the truck idling.
I do not need the A/C to be working during the engine break-in; is it better to leave that for another time? How?

Thank you all for the help.
