Thanks that really helped.
On another related question.
Just purchased a AC manifold gauge to test low and high side pressures and for adding freon if needed.
For those that have used them, I'd like to see if you have run into this issue.
After hooking up the low and high side couplers to the AC fittings and turning the hose valve couplers clockwise to open (the manifold blue and red ****s are left in the closed position), I take the readings, then turn the car off, turn the coupler's hose valves off by turning them counter clockwise and remove the low side first then the high side connector. The low side comes off easily with barely a whisper of pressure, but when I remove the high side coupler, it spews, forcefully for approx. 2 to 3 seconds, freon from the hose coupler, that was built up in the hose!
Is that normal?
Seems like such a waste of freon. Glad I don't have longer pressure hoses.
By the way, the high side coupler is quite hard to attach to the fitting and requires a fair amount of pressure to push down and make a connection. Don't know if that has anything to do with the above issue.
