I just got my Mustang a couple of weeks ago and not much is known about what has or has not been done to it. The A/C system is very questionable. It doesnt blow very cold at all. The service ports on the compressor look like one has a 134a fitting on it and the other has the R12 fitting on it. I am trying to determine if it has been converted or not, or if someone just threw a fitting on there and dumped a can of A/C PRO in it so that it would work long enough for them to sell it. So my main question is, are there any markings on the hoses that show they are for 134 or R 12? Is the expansion valve different? I have seen in some posts where the expansion valve is inside the air box and has a probe that goes down into the core. Mine is mounted on the line in the engine compartment and looks like the picture below......
Here is a pic of the service ports.
all the hoses are painted so hopefully only the top is painted.
The clutch seems to work fine and the compressor too, so hopefully that will be ok for a while. At some point I suppose I will convert to the sanden style compressor.
Looking on the Original Air site, they dont specifically state if any of their parts are for 134a or R-12 for the most part at least. Which is kind of annoying. I know the original R-12 hoses wont take the pressure that the 134a runs at, and you need the inner core type of lines. They dont specify that on their site, so I am wondering if all their lines are 134a compatible and can be used on either R12 or 134a which would make sense. I just wish they would tell you either way. Same for the expansion valve. Im pretty sure the orifice size is different since it is on my Bronco. But they dont say anything about that either.
Any help would be great. I just want to be able to ask intelligent questions when I get them on the phone.
