Recharge A/c
I need to add freon and am not sure i have the low side port. It has a black cap on it and is like a big valve stem but metal. I have charged systems before, but the guage i got and hose is to small to fit over this fitting. I have never had to have any kind of adapters to charge any other ones with r134a. Is this the right port or do I need some adapter. Let me know where the port is at or what I need. 97 eb with rear air

found it and added 18oz. it took it fast and it seemed to get colder, but not cold enough. clutch is staying on and not kicking off. the guage was showing blue which is supposed to be full, but seems like it needs either all new or more. what do you all think.

You cannot tell how much refrigerant is in the system by the pressure shown on the gauge. The best way is to evacuate the entire system, put a vacuum on it and then recharge the system with the correct amount of refrigerant. Also add some dye to the system before you charge it again. After this is done you can check for leaks and for a plugged condenser or whatnot.

Mrcmk is correct. Just adding some refridgerant to the system is like using a wad of chewing gum to fix a leak in your oil pan...................It ain't gonna work very well. Sevice the system to get the maximum cooling efficiency from it. Dan.
