Look at the colored pressure caps on your A/C lines. One is labeled with a H and the other with an L. The L is the low pressure side. Should be the smaller of the two

Add freon

You have to locate the low pressure line and connector port. Trace the two lines back to the firewall that come from the compressor. You will find 1 port on each line. They are usually covered by a plastic cap of some type that unscrews. Your refill hose, assuming you have a standard refill can with attached gauge, will only attached to the low pressure side. The two ports are slightly different in size. The low pressure side should be the larger of the two lines you are tracing from the compressor.

Im looking for the low pressure port on a 96 ford taurus ?????

Oh, that's an easy one. The low pressure side is made up of larger diameter tubing than the high pressure side (aluminum tubing) that holds the refrigerant.

Also, the low pressure side always gets cold when working properly with the a/c on. The cold low pressure side piping will develop condensation on a hot day.

Sometimes the low pressure port is located on a post that sticks up and has a blue or black cap on it, similar to schrader valve but different.

The quick connector connects to the hose found in an r134a kit that may have a 12 oz. can of r134a for bumping up the amount of freon in your system (sometimes cars leak this gas slowly through o-rings).

Good luck to you on this.

I have a 1996 Ford Taurus GL and need to add freon

if the port you are trying to connect to is bigger than the connector on the hose, then that is the wrong one. that's the high side. you want to connect to the low side, which is a smaller fitting. the fittings for 134a are quick disconnect.

Where is the port to add the freon

if u didnt find your freon port, the low pressure side is on the passenger side next to the firewall. Notice where the strut is bolted and look a little further in. Hard to see and hard to get to. Hope this helps..

Location of the a/c low pressure port in a Isuzu trooper 91 v6

The low pressure side is the line that gets cold when the ac is running. It usually will have an inline dryer canister attached to it. Kind of about the size of a 16 ounce beer can. Close by you should see the port connection to add more freon or r-134 whichever your system uses.
