    I have a leaking shroeder valve on the low side ( service port). Freightliner do not sell the shroeder valve tool. I went to O' Reilly , Advance and Auto zone, and I couldn't find that tool to remove the bad valve stem . I tried using the valve stem removable tool and it didn't fit . Is this tool different from a tire's valve stem tool? Is the shroeder valve also different from a regular tire valve stem ?

    AC Schrader valves use a larger tool than a tire valve. The cores can vary by style depending on the truck. Sometimes they sure can be stuck good and I have even broke many of the tools trying removal. Might just be further ahead to replace the line with the service port on it and be done.

    I had one that was leaking and ran in to the same tool availability problem.
    I was able to drain mine down and then put a few drops of pag oil down in the valve and then worked it up and down a bit and then recharged it.
    It’s been holding since March with zero leaks so far.

    Pag oil is the oil used in air conditioning systems.
    You can buy it in any parts store.

    I purchase the tool, but I didn't change the Schrader valve. I also got some PG 100 and put around the Schrader valve. Let's see how it holds up
