I have a 1991 Mustang GT with only 58k miles and is no longer blowing cold. Before the car went into storage, everything worked great.
I also have 3 cans of R12 left....I am sure you know where I am going with this one.
But before I simply recharge the system, I am concerned about leaks and loosing my valuable R12.
I have been trying to learn more about replacing the O-rings (with the Green ones and Nylog), but now it seems if I open the system, I will be forced to replace the dryer as well. I am assuming I have a leak somewhere since the car no longer blows cold.
Of course, converting to 134a is still an option.
What would you guys recommend here? I am new to servicing A/C....are there any documents that pertain specifically to this car that I can grab off the internet?
That's a big problem with not running an a/c system for a long period of time, it will create leaks after a while. I suggest repairing the leak, or even better, replacing all the o-rings in the system, keeping it R12 and replacing the drier/expansion device while you have the system open.. Those two items are fairly inexpensive.
From what I can tell, when driving in the car, the compressor is engaging and disengaging, but I will have to test it in the driveway and try jumping the switch.
I do have two older mustangs (86 and 67) that I can save the R12 for as well....I am assuming those compressors are even worse at handling the 134a conversion.
Don't jump the switch without checking the pressure first, don't want to run with zero pressure. If there is some R-12 left, but not enough, go over it with a leak detector and try to find the leak.
Where can I get the proper gauges in order to help me out here? Harbor Freight?
Right here of course

Do these connectors matter for R12 and 134a cans?
You will need a can tap aslo.
