<div class="bbWrapper">I have the r12 to refill a/c but cannot find the connection to the fill port. It is not the modern clip on it is a screw on 7/16 x 20 hose needed for connection.

If your system is flat you will want to add either nitrogen to try and find the leak using soap bubbles at all fittings or add some R-12 and then use a electronic leak detector. Don&#039;t use air to pressurize the system. After repairing the leak you should replace the receiver/dryer and use a vacuum pump to remove all noncondensibles before recharging. The low side port is the one that goes to the firewall and the highside port goes to the condenser next to the radiator.</div>

If the stem type service valve is in the front seated or back seated position, the service port is closed and there will be no pressure readings on the gauge.

As the diagram of the valve shows, if you screw it in all the way you close off the other side of the valve. In that position on these old systems it allowed you to close both the high and low side off to the entire &quot;plumbing&quot; of the car and then you could remove the compressor by unbolting it from the valves and put a new compressor on without having to empty the freon out of the &quot;plumbing&quot;. This multi-position multi-function aspect of these valves can make it confusing. Normal operation requires the valve to be completely &quot;unscrewed&quot; so it seats so as to close off the charging port. Service position with a gauge set installed is with the valve in &quot;neutral&quot;, i.e. screwed in halfway. &quot;remove compressor while system is still charged&quot; is screwed in all the way.</div>
