Greetings all,

My apologies if this has been covered here before, but I couldn't find an answer searching.

What is the best way to check the A/C charge on a non-running 1984 300SD?

Background: I'm preparing to pull out the engine and transmission to either rebuild them or have them rebuilt, and I need to disconnect the A/C. From the looks of things under the hood it's never been converted over to R134a. It's not running so I can't test by turning it on.

So, is there any way to find out if the A/C is full of refrigerant? If it is I'd like to pull that out and see it safely recycled.

Thanks,
-Marcus
