IS SUPPOSE TO LEAK FREON WHEN REMOVE CAP FROM HIGH PRESSURE VALVE?
1997 GMC Jimmy • 10,500 miles
My car is leaking freon
The valve is bad if freon is leaking from it without the cap.
How do i remove the valve?
You cannot do it without discharging the freon in it. Go to an A/C shop and ask them to do it for you which is done without discharging the freon into the atmosphere, unless they are non-licensed.
