How do you add R12 freon to a 93 Honda Accord?

R12

R12 is now illegal to use. older cars still using it are okay, but no shop will fill it or fix it using r12. you are required to have the freon flushed and the ac compressor oil changed. you then need to buy an adaptor kit and upgrade the system. You need to then use R134A Freon. R12 was banned because of what it did to the environment. Check with a local auto parts store before you attempt to use R12 and get more info.

It won't tell you in your manual.

Adding freon is something that should be left to someone that knows what to do and has the gauges to measure how much is being put in. If you put too much in, you can damage your air conditioning system.

Now for the other side of this. Nowdays, a shop can't just add freon to a system. They have to pull the old freon out, check the system for leaks, and repair the leak if found before adding freon. Something that gets to be expensive very quickly so I can see where you would want to do it yourself and save a lot of money.

See if you can find someone that will do it for you, use your freon, and not go through all the crap. maybe a mechanic that will do it on the side or something...
