E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

How to tell if my A/C was converted?

Is there a definitive way to find out if my car 1990 325ic was converted to 134a?

Everything looks old but I have an adapter "quick connect" fitting on the low side. I don't know if that was put on just to make it convenient to use the new gauges.

The system does try to run and at times does seem to feel cooler, but I think it is low and does not cool great and I want to recharge it.

I can get both r12 and 134a so I just need to find out what I need to put in the system.

I have looked in the engine compartment and I cannot see any stickers saying it was converted.

Any help would be great.....thanks

You will have an adapter like this on your factory hard lines it's fairly obvious if some has changed it out.

Chances are it's either been converted or someone put the adapter on just to do a pressure check or top it off with R134A. I know several people who have just put R134 in R12 systems without doing anything. Mixed results of course... I'm not aware of an absolute way to determine what it's got in it. But the adapter is a sure sign someone's messed with it at some point.

Other then that quick connect it all looks stock and untouched.

I but it was low and someone thought they would top it off from a can at Autozone and realized they needed an adapter.
