940 r134a ac valve core tool

[white855T]

I have a leaking ac fill valve(right next to drier). I have replacement core but a standard core tool does not work. The core is much deeper in the valve. Any sources for core tool or a method to removing core?

Valve core like the shrader valve? Any auto parts store should sell one, same you would use on a tire.



Yes maybe I've broken this tool 4 times but they warranty it no questions asked.
The only time it doesn't work is GM ball valve style

I couldn't tighten my core until I realized I needed to take off the quick connect fitting in order to access the shredder valve. That was a brain fart that lasted several weeks.

There's also tools like this that let you change the valve core without discharging the system
