Hi!
Got a question for you guys.
I had my a/c converted to r134 a couple years ago, before I knew about cars.
They replaced the required components (condenser, evaporator, and accumulator...?), so I'm told,
but left the R12 fittings on it.
I know there are adaptors, probably they used them.
It's time for a recharge-- cold but not icy cold.
I bought R134 fittings at the local parts store.
Looks like they're threaded.
SO, if I unthread the R12 fittings, will my system just vent everything to atmosphere?
Or are those fittings schrader valve protected, I can unscrew them, screw in the r134 fittings, and proceed with the recovery/charge machine as per normal?
Let me know before I break those fittings free! I won't know if there's a schrader valve underneath until it's too late!
Thanks,
-Bernard
