Hmm, ok anyone happen to know if there's any particular size to the low side of that R134 in my 83' 300D? I started calling a couple auto parts places and they are telling me that there are lots of different sizes... I was hoping that by some miracle I might be able to get the valve swapped without losing the ENTIRE charge of R134... Or am I just dreaming? Of course this would necessitate having a new one ready to go before pulling the old one...

It's a Schrader valve, but not exactly the same as a tire valve core. They often start to come unscrewed, I've tightened a few which has stopped the loss of refrigerant. The usual tire stem tool will do the job, or perhaps even a pair of hemostats. If the valve itself is shot it's easily replaced, but not easy to do without losing all the charge! (There are specialized tools for doing this job.) Possibly the nasty oil/R134a combination has eaten the valve's rubber seal. Nobody ever talks about replacing the valves with R134a-rated ones. O-rings, sure. Hoses, yes indeed. Valves? Dead silence. > Also, should I be seeing a lot of oil, or is that a sign that there's > too > much in there? Oil is mixed with the refrigerant, so any leak should bring some oil with it. If you lose enough you should replace it. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
