Hello and thank you for your questions,

Can you tell me what your working on? Year, make and model please?

06 Ford five hundred. AC recharge
Expert:  Ron replied 10 months ago.

Thank you for that, The low side suction service port is in the suction side line coming off of the compressor which is the lager line a few inches back from the compressor. See the link below, copy and paste the link to your browser to open and view it. I have marked it for you.

this answer was free on all kinds of sites.. without being disrespectful, im not sure i would have paid for the same answer .. why would anyone.. so here is a question.. can you give me your thoughts on why after recharging and sealer installed.. it still gets cold at higher revs, than at idle..
Expert:  Ron replied 10 months ago.

Can you tell me your pressure reading on both the high side as well as the low side with the AC on and the compressor running?

Customer: replied 10 months ago.
Expert:  Ron replied 10 months ago.

In order to determine why the system is not cooling properly as you have mentioned you need to start first with installing a set of AC gauges and read the system pressure. Are you able to do that?

Gage was at (low)90 with engine off and once I started it it drops into good range 30-55. When I rev engine it drops to lowest but doesn't go below "blue range"
Expert:  Ron replied 10 months ago.

Normal pressure on the high side and the low side with the compressor off should be right at 100 to 110 PSI. With the compressor running at idle you should see 35 to 40 PSI on the low side and right at 200 to 225 PSI on the high side. If you reading 55 on the low side with the compressor running that would indicate you are over charged providing the high side pressure is in the correct range. The problem with the cheap charge kit is the reading are not as accurate as they should be.

Oh ok. So a) why does it drop at higher rev( my understanding of that is low coolant. And b) how to I discharge excess if you are correct
Expert:  Ron replied 10 months ago.

The suction side is suppose to drop while revving. Before you discharge anything you really need to check the high side pressure.
