Where is the low pressure port for A/C located?

Hi,

The owner's manual won't supply that type of information. From the compressor, there are two steel lines. One will be bigger in diameter. That will be the low-pressure line and the one that will receive the Freon. Note that although the steel line is bigger in diameter, the actual connection on the low side will be smaller in size.

Here is a video that shows different makes and how to locate the low-pressure recharge port:

Also, here is a link that shows how to recharge the system. It explains as well what to look for.

Let me know if this helps or if you have other questions.

Take care,

Joe
