I have a 1986 Mercedes 190e 2.3-16v and the air conditioning has been converted over to R134a. I want to evacuate the system and replace a couple components and refill the system. Can any one tell me how much refrigerant to put back in to the system? I am looking for a number of pounds or grams of R134a to put back in the ac system. I was thinking it was about 2 pounds but I have forgotten.
