Hi, anyone know where the AC low side port is located? I have AC Pro and want to check the low side port pressure and determine if I need to add refrigerant, but I can't seem to find any info or pictures of where the low side port is located.

Thanks! That's the one I thought it was. Hooked up the AC Pro and could see the pressure rise and fall when the compressor cycled on and off. Turns out I didn't need to add any, the levels were within limits. I will take some temp readings, but guess that my system is OK, it just didn't feel as cod as it used to, but I could be wrong.

 

Yes, definitely get a thermometer...
I just checked my temp idling in the driveway, it's 82° outside
and 45° at the center console vent.

 

Where the arrow is?

 

Do you see ant other :"low side is the top port between radiator and engine right side. 'larger diameter tube' ".... in his pic from FOUR YEARS AGO?


Since that is the only port visible matching the poster's description, that would be a Yes.
