Have myself a self-inflicted problem. Connected a manifold set to my 2009 F250 6.4L A/C system and the schrader valves for both the high and low side will not seat all the way. I have tried the tricks of pushing down and letting it lose in hopes it would seat automatically. Both still have a slow leak. I put the caps back on but need to get those valves replaced ASAP. I need to get the tool that allows me to change the valves without losing the freon. What size are the low and high side schrader valves? 8mm and 10mm? TIA.

Thanks estop. Often times I find answers on forums that I do not subscribe to and am too lazy to go through the registration process to thank the poster. That is not the case this time and I thank you for the follow-up. I do my best to answer my own questions with follow-up posts when I can. Invaluable information.

Thanks again
