My system was completely empty. while Dan (my fab guy) was working my bumper a bar had fallen and put a hole in the condenser. When it was replaced anything that was in the system was removed. I did not check for leaks before filling, based off of the fact everything was ok before the mishap. I picked this up (Quest/R-134a Sub Zero refrigerant). I used the fitting close to the firewall on the passenger side, that appeared to be the best bet per the instructions. Based off the gage that came with it, one bottle was just shy of full. It seems to be working great. I will run for a few days & might pick up a small bottle that works with the kit to top it off at full.
Will see how it goes from here.
BTW thanks guys for your input.
The funny thing is it never gets hot here & when the ac went down we get a heat wave high 80's. Here it is a heat wave, also the humidity was high which is not normal here. so this last week sucked.
