Do a search on the forum. Some have posted links to software that contains the entire manual.

Or, purchase a FSM in book form.

If you use a GUAGE, you'll know the low pressure side. Most refill kits will only connect to the low side, the 2 ports are different sizes.

The AC line pressures are critical. You should also consider adding the correct oil charge before you add freon.

If your A/C is low on gas,there's a leak somewhere,which really should be found and repaired,unless you just plan on adding freon every so often...

If you have a leak, the super sealer will work. The evaporators are terrible to access on these cars.

This is what I mean:
