I've finally scored some R12! Got three 14 oz cans of the stuff!

I'm working on my older W124s (89 and my 92). If the 92 was a M119 car it would be a R134a car!

I've already done a search here and on another site which lead me to a thread which had a link to the factory manual: 83 Climate Control System

The problem is the manual still didn't answer my question! Simply put, as stated in my title, which way do I hold the can? Up for gas, or down for liquid? (Different cars have different requirements in this regard.)

I think I've already established where the low presure side is (high in the engine bay, closer to the firewall on the driver side).

Thanks to all who respond!

Regards,
Eric
