Re: [DML] Re: AC Question - 3 of them with a little surrounding information.

If your pressures are at 20 on both sides when the engine is running, you defiantly are low on freon.  Worst case is that your compressor is shot and bleeding over.
 
The Freeze 12 will work fine, but don't add it to your system without completely evacuating and vacuuming the system for at least an hour.  Then check if it holds vacuum so you know you don't have any leaks.  THEN recharge.
 
I tried the Freeze 12 while I was troubleshooting another problem.  I didn't want to put my real R-12 in if I was going to have to evacuate it to change a part.  After putting the Freeze 12 in and verifying my system was functioning properly, I couldn't convince myself to replace it.  My center vent temperatures while running the Freeze 12 will dip below freezing at times while the engine is revved (as long as it's not 100 degrees outside).  That's good enough for me!
 
Also, clean your evaporator (details in the archives).

Ran the same check with my car running and the AC turned on max. 
Same pressure.

Does anyone know if the AC R-12 Substitute Freeze 12 found on the 
specialtauto.com site can be added to the regular freon that I 
already have running through the lines? Chances are, I am not going 
to get regular R-12 unless I take a treck down to Nogales.

If the substitute works, then I just may charge it up, and see how 
we do...

Thanks
