I believe you will find this only if car is on a hoist-- as I remember it is near the compressor which you cannot see unless the car is lifted up first

AC low pressure valve

I discovered you can access this port, it is inside the drivers front wheel well, behind the protective covers

 

[teginder81]

The low side port is right behind the ac compressor on the line. Yes it is a pain to get to. You have to go in from the underside to connect it.

See below. You can buy Ac Pro 134a refrigerant here which helps seal leaks

If you want to DIY check out this R134a R12 R22 R502 AC A/C Manifold Gauge Set 5FT Colored Hose Air Conditioning

Thanks for the info "tbird"!! So the low side port is #5 (with the red arrow) I assume?

What is #10 on the illustration, the EASY one to get to. (Thanks, Henry!)

And, can you use car ramps with Birds, or is there too much stuff in the way???

BTW, I have used progressive thicknesses of concrete blocks/bricks to get under one. Old shade tree man here. 🙂

#10 is the high pressure side,. A/C Pro will not fit this port. hydraulic and jack stand work well.

I replied mid week to the location of the low side ac charge port on my 02,guess it did not make it.I would suggest a pair of drive on ramps for anybody doing service to there own birds.You can gain access to the low side port by simply driving up on your ramps, removing the plastic panel on the left front corner,under compressor.The port is on the rear of compressor.This is a safe way with out any tire removal.Ramps are also good for oil changes etc.Have fun,be safe.

 

[jamel95]

Note that the plastic panel people are talking about is not the fender liner but the lower panel above the control rod. 🙂 charged, lets see if it holds. took all 20 oz of AC Pro. didnt get to yellow zone on the gauge

I would like to add i myself own a pair of plastic ramps, purchased at o,reilys that work great for the t bird.Get a nice low profile creeper , and you are all set for safe underside inspection,maintenance , or a nap on a warm summers nite till she comes home an grabs your ankles to see if you are ok...Head against bottom of bird..LOL

I got to the low side by just turned the wheels all the way to the left and popped the clips that hold the plastic panels in place, slide them out of the way and there was the low side port. No ramps or jacks are needed.

This is exactly what I did, until I decided to replace compressor. There was a good amount of green oil underside, so compressor leak had gotten bad.

New compressor works great, ice cold.

The charge on my 2002 is 28oz. It is written right on top of the radiator shroud.

 

[jamel95]

thanks, I will add 8 oz. I missed that notation.

For those of you who want to know how to find the low pressure a/c port here are some photo's from my 2002 bird.

My air condition in my 2002 does not get very cold. I think it needs a charge. What type of Freon does it use. Also I do not see a window to check

 

[Netconn]

It uses 134. 134 systems don't use sight glass like the R12 systems did. You need gauges and you fill to proper differential pressures for ambient temp. The best way is to evacuate the system and fill it with 28 oz of 134 - With Gauges.

 

[edward301]

When you fill put fan on high, rev engine to 1500 rpm, fill till
low side gets to 26 psi.
