Georgets Posted July 14, 2009 Author Share Posted July 14, 2009 Thanks Blake918!! That's the port I thought! But I don't have the cap on it so I wasn't sure. Any idea what the pressure suppose to be? I'm trying to use Interdynamics refill kit like the attached picture shows. The pressure was over 100psi into the red. Now that I'm thinking about it, I don't have the bottle connected to the gauge. Maybe that cause the pressure to increase?? I'll try it tonight with the bottle and see. I appreciate the help!! Quote Link to comment Share on other sites More sharing options...
Georgets Posted July 16, 2009 Author Share Posted July 16, 2009 OK, the port works. Once the AC runs for a bit the pressure drops. Added the Freon and almost all is well. The only problem is the pressure is a little high. It's around 40+psi on the gauge. Would I be able to press on the pin and release some pressure? Would that be the proper way to lower the pressure? Thanks. Quote Link to comment Share on other sites More sharing options...
