Can I ask for where is that in the engine compartment?
For my 2003, the A/C compressor, and therefore most of its plumbing, is located at the very bottom of the engine compartment. So it is pretty difficult to follow the "piping" and thus to ID the components of the system (like which of the cylinders is the accumulator).
There appears to be two service ports. At least from what I can find. One located right next to the passenger side strut tower brace, and another is located right next to where the upper radiator hose enters the radiator itself.
There are caps on both of them, but neither has any markings to ID its purpose. All that is on the caps, it he name of the manufacturer of the cap, and its thread size.
Which one of those two ports I found, is the low pressure service port? Can anyone help?
EDIT:
Here is a pic (not my Mustang though), with yellow arrows pointing to the two ports I found...
*damnit! my jpegs were too large-must shave 'em down so I can attach them-gotta go to work now-will post later-sorry.
Can you tell me via looking at these sub-optimal quality digital photos whic is the low pressure port?
regarding the pic that includes the strut: one cap is green and the other is black(sorry,i don't know how to draw arrows to them )
in the other pic,the black cap is close to the radiator hose.
thanx
This is a old post, but I need to plug a a/c gauge up to see what my psi is at. After 8 years I don't have that 60 degree a/c anymore. Pics posted from the last guy. I'm just making sure which cap is the low side. One cap is green and one cap is black.
