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.

Thought I would follow up in case someone else has this issue in the future. The valve cores are 8mm and 10mm. They are referred to as Eaton Schrader valves. So if you ever want to change out valve cores without losing freon the correct tool to get is an Eaton valve core removal tool. Mastercool sales one. They are expensive, but they may save you money on a complete recovery, vacuum and refill job.

Had a similar problem on my Cobra. Was only leaking at the schrader valves on the high and low side. Hard to find lines so I just replaced the valves and all is well.

sometimes the valve just needs snugging up a little, they can back off with the temperature changes
a common tire valve tool may work, or one of the extended tools
there are a couple of different schrader valve core sizes that are common
I have the mastercool set, that is the only way to change out the valve core without losing the charge

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

I have had this issue on a few vehicles and my resolution was to buy the extension from ebay .. they have a shrader also and depress the OEM shrader when depressed so it can be left in place and no freon loss ,, they sell them for both high and low sides
