newbie 1993 525i Touring

Hi all!

I was wondering if any of you can tell me the capacity of my AC system. I put in about 19oz of 134a the other day....it's pretty low at the moment, I am expecting a leak but I'm not sure how much this car holds can you all help?

BTW I just purchased the car so I dont have much history on the AC system.

Thanks,
Brandon

Look at the underhood stickers, one of them will have all the information you need for AC, tune up, model year, displacement etc.
