Re: 97 Chevy c1500 a/c help needed…

If you haven't already done so, pull out the Orifice Tube (OT) and examine it. It might be partially blocked with gunk and metal particles. If it is, I'm afraid the system will need a lot more work.

Re: 2004 F-150 Heritage AC

That's good. No, it wouldn't circulate the solvent.

Re: High pressure side never drops, even when car is off


I evacuated the system before I recharged it, and the part I purchased claimed to have the R/D already in it. I did measure the refrigerant by weight.
Regarding the amount of PAG oil I put in, I don't recall the exact amount, but it was in the neighborhood of 1.25-1.5 ounces. I did get it from the ...

I don't have a diagram for your compressor. But ACKits.com, this Forum's sponsor, can have your existing compressor rebuilt as long as the mainshaft still rotates smoothly.

Re: 2004 F-150 Heritage AC


Well, it looks like I could not keep my mind on what I was doing:
I proceeded to flush the evaporator, and when I was done, I hooked the lines back up and realized afterwards that I forgot to dry it out with air and I also forgot to add one and a half ounces of pag to it.

Is it possible that if I ...

Re: AC Leaks - O-Rings vs Lines


I appreciate that feedback, especially since it looks like I still have a small leak at one of the connections to the receiver.
Even though the o-rings were replaced, it could be possible that one or more were a bit too small in diameter, and therefore, leak under pressure.

When you get back ...

Re: AC Leaks - O-Rings vs Lines

I would not replace the lines—especially at that price—unless there's some kind of obvious mechanical damage. (There isn't, at least in your photos.)

To ensure a leak-free system, always use a dab of Nylog Blue on each connection point, threaded joint, and o-ring that were disassembled and ...

Re: High pressure side never drops, even when car is off


My daughter has a 2004 Mazda 6 2.3L that was in an accident and was totalled. The car has been very reliable, and it was only the front end stuff, so we took it to a body shop and had them fix it. We took another daughter's car there a few years ago under similar circumstances, and we were very ...

Re: 1999 Toyota Camry

A few questions, if I may:
Did the system hold a vacuum for at least a few minutes? Did you attempt to re-charge it with the A/C system and possibly the engine switched off? And how did you re-charge it, by weight or pressures? What was the original reason for the re-charge?

Re: Evaporator replaced but freon smell remains.

It could be residual oil and maybe UV dye that you smell because as Tim said, refrigerant by itself is odorless.

My "sniffer," an older pro model, goes through a self-diagnostic routine and sounds off when it's first switched on to let the operator know that it's working and the sensor is intact ...
