Where do y'all in the Dallas area go to get your R12 evacuated? I have been calling everywhere and no one has the tools, even the Toyota Dealership! How is that possible? I cannot live with myself venting that crap into the atmosphere.
I stuck a philips head screwdriver in the valve and it hissed so I assume it does. Or would I be incorrect in that?
No liquid, just a hiss. I will give it a more robust check to see if anything liquid comes out. I'll see if I can get my hands on a gauge that will fit those old shrader valves. Maybe I am in luck and it is just residual pressure.If you didn't get a 'liquid' spray and some oil with it....then you might only have a small amount of gaseous refrigerant left. Putting a set of gauges on it and reading the 'static pressure' (Engine off, system off) would tell us.

So I really jammed a phillips head in the high and low valves and there was hissing, but no liquid was "squirting" out, though the tip of the phillips was a little wet. I ordered a cheap gauge set so I will have more info come Saturday. Just sharing if you have insights. I really appreciate the input as a/c systems are a bit of a mystery to me. I restored a 55 Chevy but didn't have to worry about R12, just installed a Vintage Air and all was good. Different story here.Kind of sounds like it. IF you can get even a single gauge on the low side fitting and it is less than 50 psi (static pressure) I wouldn't have any qualms at all about venting that small amount of residual gas to atmosphere. A single Cow Fart is more damaging. IF you find you still have liquid refrigerant in the system...then that is a different story.
