does anyone know what the capacity of a/c system on a 92 D-350 in my sig is? I am speaking of R-12 of course. Am thinking of trying Duracool 12A. Has anyone tried it?

 

I've used Freeze12 on several original R12 systems. Seems to work fine. I get my kits off e-bay. In the kit you get the recharge hoses and fittings, oil, stop leak and the cans of refrigerant. I converted my old 70 Plymouth Sport Fury to the Freeze12 and the car was a friggin meat locker.

 

36 oz of r12.

 

thanks for the replies guys!
