Well I just got certified to buy R12 and now I have an 82 240D to fix. The air conditioning does not work due to low freon. I know that there is a leak, because we refill the system every year and it works fine. Since this is my first time, I was wondering if someone could run me through the process of charging the car.

I am prefectly williing to go out and spend the $70 on gauges and possibly some money to buy a vacuum pump. I have 3 cars that run on R12 and I think its finally time for me to get my hands dirty with A/C.

What tools do I need to charge up a system and what tools to do I need to evacuate a system and then recharge it?

What tools do I need to test for leaks and how do you go about doing that?

Thanks for any help!!!
