A/C Line Replacement Question
I have a freon leak on my a/c hose from the compressor to the drier and am going to replace it. What disconnect tool do I need for the lines? I've read that a fuel line disconnect tool will work, but the ones I have won't work...

I was curious if this one would work?

Also, will I need to replace the dryer if I'm just doing the hose?

Fuel line disconnect works just fine for A/C lines. I highly recommend getting a metal tool as the plastic ones are typically really flimsy and I've broken/disfigured lots of the plastic but my metal tool is going strong.

Alright, I had replaced my ac lines the other day on the compressor and had the system vacuumed and charged. My ac worked ok for a couple days and now it is temperamental. Sometimes it blows cold, sometimes it doesn't. The compressor is always running, and I've noticed the low pressure lines aren't cold to the touch.

Also, is it normal for the line where the orifice tube is to be 2 different temperatures? The side of the line closer to the firewall is cold, but on the other side of the orifice tube, it's hot. Is that normal? I can also hear almost like pressure releasing from the orifice tube when I turn the truck off.

I don't have any leaks and the system is building high head pressure... So I'm wondering if I have trash in the orifice tube?
