I have a 1997 GT. Both my high and low port o-rings are gone so the A/C system will leak out Freon in the matter of hours. I was going to replace the lines, BUT some folks say that you can just replace the ports and Ford carries the ports so they must be replaceable. So my real question it...

How do you replace the high and low Freon ports?

You talking about the Schraeder valve - little spring loaded thingy that looks the same as a tire valve?

There's a special tool for them (Schraeder valve removal tool) and they just unscrew.

Once you put new ones in, hopefully you are aware that you can't just hook up a can of 134a and fill the system. Prior to filling, a vacuum pump must be hooked up to it, which serves two purposes - verify that the system is sealed, because it won't be able to pull and hold vacuum if there are any leaks; and the other is to remove atmospheric moisture from the system which will have gotten in when you were changing the valves - refrigerant and moisture do not like each other, in any amount, and making the two hang out together will cause corrosion of parts and components internal to the cooling system.

Regarding the vacuum pump and properly recharging the system this is best left to a shop, just in case there's any ambiguity there.

My car does not have Schraeder valves. It is the old ball style valve with an o-ring inside. It is R-134a though. Don't why Ford decided to do that. I managed to unscrew with low side, but can't get the high side lose

Beleive it or not the damn thing unscrew as a whole. There is a special socket to remove them. However *cough* channel locks *cough* if you dont need the tool you wont use more than three times ever. Be gentle either way you booger the hose and your up an unsanitary tributary .

I got the low side unscrewed, but the high side wouldn't unscrew. A week later I spent $15 on both valves to see how the high unscrew and it just came out! (With channel locks of course) Filled her up with some Freon and no leaks with 48 degree air blowing out now.

Thanks for all the help guys! It is much appreciated!
