A/c Question

I have detected a leak on the schraider(sp?) valve on my 560 sl 1986.
being that it's an R12 system, I'll be losing expensive freon for just changing the valve on both hi and low ports. My question is,
IS it possible to use a 134 A quick connect retrofit tips and use them for r-12 delivery and monitoring(manifold gauge use)?

I know that I need to mark them with big bold letters : COLOR=red]R-12 system!!![/COLOR] But this will make connecting gauges to an r12 system more efficient (Don't you 'all think so? . I do have both R-12 and 134a gauges. Suggestions are very welcome.

There are valve core tools for replacing them without losing the charge.http://www.ackits.com/index.cfm?fuseaction=Vcst

Better than relying on a compromise solution.

awesome!

jbaj007,

Thanks for all the help.. I'm ordering this tool .RIGHT NOW!!
I guess they don't happen to make "quick connect " kits for R12 , huh?

I also found a red dye that you actually can either push in with a socket wrench to "sqeeze" the dye in or tap in with the refrigerant, between the service hose and the port. No need for UV light...it's redder than blood... you know what I mean??It's suppose to be water soluble and should be able to be cleaned up with water/soap sol. ( should)-- Do you have any experiences with this product? JUst concerned about clogging up stuff in the system. Thank you so very much...


Happy motoring
