    The first time I replaced the heater core,I took the car to a garage to remove/collect the R-12.
    When the mechanic was finished we were talking for awhile and he said,
    "I was glad when you said that you are doing it yourself".

    Even a mechanic didn't want to do it,lol.

    It's a mind over matter job often times made worse by an aftermarket stereo and or gauges.

    Did you need any special tools? Like a manifold gauge set? I’m diving into my fox factory AC in the spring. I bought a can of dye, the filling hose gauge and a uv light. I know it works, but there’s a leak somewhere.

    You'll need a vacuum pump also, need to make sure there is no air in the system.

    You need a disconnect tool to disconnect some of the AC lines.

    I have those. I have the small hose/gauge that comes with the AC cans at canadian tire. No vacuum pump.

    Did you replace your whole system? Or just swap a bad part? Did you retro fit with r143 or use the r-12A from redtek or duracool etc?

    In 2006 R-12 was no longer available and I thought converting to R134a was a waste of money so a mechanic suggested 12a which he installed after I replaced the o-rings on the lines.
    In 2017 it needed a recharge so I bought a Duracool 12a kit on sale with gauge and installed one can myself.

    My AC system is original except for the o-rings and a few pressure switches.
    Even with under drive pulleys I get 39-40*F vent temps.

    Ice cold!
    I thought the drier/accumulator needs to be replaced with any exposure to air? They have a desiccant in them that will ruin if exposed for too long. Did you have to test pressure, or pump the air out? What about AC oil? I know the cans have some in them but was it enough?

    Soon as the lines are off, plug em off / do not leave open.
    However, if accumulator is old, money well spent to replace.
    Be sure to vac before refilling.

    After I replaced the heater core twice the AC was recharged at a garage where a vacuum was pulled on the system.
    I think pulling a vacuum also gets rid of any moisture in the system.(not positive at the moment but I think it does).

    I covered the AC lines when they were disconnected while replacing the heater core.
    I probably should have replaced the accumulator/drier but the system still works ok,but for how much longer who knows.
    Didn't need to add any oil as no major component was replaced.
