AC Port Locator
#1
Can someone help me out and post a pic of an OEM low AC port locator. Christine was retro a few years ago to R134A and
needs a recharge.

I picked up AC Pro recharge, but their site doesn't show it on a Mustang that old.

Thanks

I think the fittings are idiot proof so you cannot hook to wrong one. You should put new charge in with the leak detector in it. Will show up with a black light where the leak is. Go to youtube there should be a video showing also. If the PO did not put the adapter on for the new refrigerant the connection will not fit the old R-12 connection either. I cannot tell you off the top of my head only charged mine once over a year ago.


When a man is in the woods and talks and no women are there is he still wrong??

Mine was converted to the new 134a 3 years ago, so it should have the correct nipple. Just need to find it.

I'm starting to believe that maybe my AC isn't factory.

Looking at the pics the black cap once off does accept the adapter from  the ACprocold kit.  But that metal tube goes
to a condenser/radiator in front of the stang.  Both circled in white.

Just don't want assume anything.

Thoughts???

The low side tap should be in the line from the evaporator (inside the car) returning to the compressor. See the diagram below. Follow the lines in your set up to determine. Just a heads up, those one side AC charge kits at the parts store are not great. Very easy to overcharge and ruin your system. I prefer to use an actual set of AC gauges and take my readings from both the high and low side so I can calc the diff properly.

While there is a hose coming from the firewall to the compressor, there is no ac port on the hose.

Mine looks like the low side metal tube is from the compressor to the condenser (top) and out the bottom to the receiver dryer and then back to the firewall.
Plus the only port the ACPro hooks up to is the black cap once removed.

hmm.

can you take a pic of where the low side from the evap connects to the compressor?

Here are two pics with a white line showing below.

1) Shows the metal tube from the condenser which connects to a black hose.
2) Black hose which goes to the compressor (black cap is the only port that the ACpro connects to).

In your pic. The line coming out of the compressor with the red cap on the service port. Where does that go? Back to firewall? If back to firewall is it the line that does not go through the suction valve?

The red cap hose goes back to the firewall with a red cover on it. Pulled the red cover off (no port), but sort of a coil inside and there was something like felt inside the red cover.
