1999 Saturn L200 Freon

let me explain, it could be up to 100.00 per pound. you probably have anywhere from a pound and a half to a two pound system on that saturn. but if your needing a refill then you have a leak. these are sealed systems like a brake system. if your repeatedly needing to fill your brake system up somethings wrong. get my point. do a leak detection. you can do it yourself just go to your local parts store and get a leak detection kit. Also you can fill your own system up by buying a couple of cans of r134a and doing it. I know its intimidating but don't be. just follow directions and you'll be alright. besides your gonna save big money.
