This video shows my experience changing out an expansion valve for a 2011 - 2017 Honda Odyssey that was having intermittent cooling problems. Both the high and low side freon pressure readings were incorrect causing the air conditioning to only blow cold for 5 minutes. See video links at the end of video for changing out AC compressor or electromagnetic clutch & pulley.

The flat port seals on the expansion valve are about $8 each OEM at Honda. ...and yes they are a pain in the rear to change out
