Default A/C Turbo - how can I get to the low side port?

I have a 2003 GT. I need to recharge the A/C. How can I get to the low side port? This appears to be located on top of the compressor, according to the Haynes manual? Is there a way to get to it without tearing the whole front of the car apart?
Thanks.

Don't know for a fact, but did you try taking just the front grill off or look from under the car?


...and if you don't like my answer, I was looking around Google for a better answer for you and came across this on "Answers.com" about someone asking where the Low Pressure port was....

They removed the

pressure port so that we can't charge it.

Only a technician can!




Now if I can ask you: Where in the Haynes manual did you find anything about where the Low Pressure Port was? Supposedly Chrysler changed it in 2004 to near the compressor but you said you have a 2003. Before 2004, both Low and High ports were right on top near the passenger strut tower. I have both the 01-03 manual and the 01-09 manual (which is mostly just a copy of the previous one) and I can't find anything about the GT moving the port down by the compressor. Did I miss something?

Sorry, wild goose chase. I was looking at the non-turbo illustration. Saw what I wanted to see, not what it showed.

There appears to be no low side port on the '03 Turbo. It's going to be a long, hot summer.

Thanks for your input.

No, that doesn't make sense. There's got to be a port somewhere and it's it's not right on top by the strut tower, then it's down by the compressor. How you get to it I don't know but like I said before, take off the front grill (easy) and if you can't see it, you'll have to get under the car to get access to it.

It's got to be there. Nobody makes an A/C system that can't be re-filled. Keep looking.

I took my can of refrigerant back to Advance Auto for a return. Told them I couldn't find a low side port. Like you, they said there had to be a port so they pulled up a picture of the low side line on their computer. It showed no port.

At that point we popped the hood to take a look at the two lines. The left one had a port, the right did not. The AA guy said the port on the left line was a low side port, attached the can and we started it up. Sure enough, it took the charge.

Felt stupid at this point because I thought the right line was the low side but I couldn't find any clear-cut documentation on the low side port and certainly didn't want to mistakenly try the high side.

Hope this helps someone else.

Good information, thanks. It clearly is different than my non-turbo as you can see on the picture below. I knew the Turbo's were different and one member clearly stated that the low side port moved down to the compressor area so maybe Chrysler did some experimenting during a couple of years or where to put it.

According to Rodcruiser, who has an 03 GT, they used the line your showing in your picture as a low side. Read post #6 above.

Thanks. I hooked up my charger but it seemed to leak at the connection when I tried to fill it and the psi gauge started to drop, not rise. What am I doing wrong?
