98 concorde recharging the ac

I can't locate the port described on the ac recharge kit I bought. It states to locate on the AC a port which will be covered with a grn or black cap. The only thing close I can find (looking under the hood facing the windshield) under the air filter there is a silver pipe with two black caps. If this is it which is the test/refill port. If not where is it?:shakehead Thanks!

I think you are supposed to fill on the low pressure port, on my m and it should be the same on your concorde, unless you have the 2.7l then maybe not, its the port facing the front with another port right on top at a 90' angle. Location is front of engine by the airbox, again on the 3.5l engine but one should have an L on the cap, you should be filling this, and the other one on top is high with H on it.

You do have the refill with the gauge right, those are better than the kit w/o it so you know your doing it right.

Low side off the ac system is a small orface..It is near the air cleaner..

Thanks! I do have the gauge so all is good.

I am no ac man but I would suggest you go to this site and ask your ac questions. Very knowledgable people there: http://www.autoacforum.com/categories.cfm?catid=2
