Subject: R134A - where to check pressure & add ?? IP: Logged
Message: I have a '97 V6 3.9L (2WD).
I need to check the pressure and possibly add. I understand this is to be done w/ engine running and AC set to MAX. I also understand that this is to be done on the low pressure (liquid?) side.
I found 2 ports w/ black plastic cap:
* one near the compressor itself
* one directly above the inlet tube leading to the air filter
Which one is the port I need to use (or are they essentially on the same circuit) ? (Tube diameter looks the same.)
I understand that the capacity for R134A on this model is 32oz. Can anyone confirm this?
Any help is appreciated.
