  1. What Now?

    What Now? New Member

    We have an '85 3L Extended cab Ranger. Last year our A/C compressor packed up but I was able to get an identical one from a Mustang. Well, identical physical dimensions. Having replaced it, I lost the complete refrigerant charge, of course.

    My questions are:

    1. What would be the best "over the counter" refrigerant to use? One store sells Red Tek 12a.

    2. After losing my complete charge, would I have to consider adding oil to the system now?

    3. Do I have to create some vacuum before attempting to fill the system?

    4. Lastly, should I do a pressure check to see if it's going to hold gas before buying some and how would I do this.

    Thanks very much for any help or references to previous threads.

  3. unless you have a vacuum pump and gauges, your best bet would be to take to a small a/c shop they will generally charge about 120.00 bucks
    thats what I was charged when I installed a new compressor, as I did not have the pump also you should buy a new drier, the shop should have those

    good luck, may want to convert to R134A since R12 is a thing of the past now days

    AH, another old post got me again lol
