find the low side service fitting this is where you add freon. start the car, turn on the ac to max and add freon. is your system r12 or r134a?

look for the fitting that is the smaller of the two and is attached to the line that is the larger of the two, this is the "low" fill side, add 2 cans of r134a freon each can is one pound the system empty holds 2 3/4 pounds of freon thats 2 3/4 cans.
I would buy 1 can of leak detector/freon combo and one can of dye/freon combo, if it takes more add a small amount of a third can that has an oil mixture in with the freon that would complete your systems needs the cheapest and fastest way possible.
If you want it done to the book then you need to have a certified A/C man vacumn pump down the system, replace the reciever drier, add freon and oil to fill the system and then check for leaks.
Happy Motoring!!

If you lost the top, then you cannot add any freon, but yes you add freon to the low line which is the smaller line.

you obviously have no idea of the procedure so it will be cheaper and safer in the long run to take the parts along to a professional brake shop and have them fitted expertly
yes-- you want to save money but at what expense and this forum is full of people who have tried cheap DIY only to find the the end cost is more than the quote in the first place

Look at the "rear" of the engine where it joins the transmission. Follow the positive cable from the battery to it. Cog with the 'teeth' you see engages the flywheel to start the motor.

It looks similar to this.

Before you add Freon, you should check the leaking first, if the Freon is too low, sometimes cause this kind problems. use color Freon test it and tight the leaking area and then add Freon, you can not do it yourself because the law say.
