My 92 D250 seems to be leaking from the low side shrader valve. I converted to 134A six or seven years ago. I've had a slow leak that has been very difficult to chase down. When I pulled the cap off the valve last time all kinds of leak detection dye ran out. is it possible to replace the valve or are the screw on conversion caps likely to blame?

I haven't done that yet. I didn't want to mess with it while it was still cooling. It's not cooling now so it's okay to play with it.

Are they the same as tire valves? I thought they'd be a different size.

There are a/c specific valve cores, but I have seen regular tire valves used on occasion.

What or why would they be different than a tire valve core? I pulled them out of my system and I'd swear they (looked) are the same as a tire valve core.........they could have been changed by someone that didn't know huh

The R 12 cores are similar if not the same as a tire core but the R 134 cores are larger and infact take a different tool.

Fact, they are available from auto parts stores, tool and the cores.
