I have a 2007 Ford V6 Mustang that has a stuck high-side A/C Schrader valve.
The system is evacuated and without pressure but the schrader valve will not turn. I've ruined two tools because the little arms just twist off. Even putting the tips of needle nosed pliers down there and turning just doesn't budge it.
Is that normal? I'm pretty sure this valve is leaking because the leak detector beeps when it's near it and there is leak detector dye down in the well where this valve is. So I don't think penetrating oil is going to help anything.
Do I have to replace the hose assembly that contains the valve to do it?
