In this video, I show how I did a full charge of the AC R134a refrigerant in my 2016 (GEN 2) Chevrolet Volt. This includes doing a leak test with the vacuum pump and pulling a vacuum to prep for a full recharge. Then I show how to do a partial recharge using the gauge set pressure as a guide to do a finish charge on the AC system.
