To be absolutely certain you are doing everything right, you might want to get a manual for your truck. I'd suggest a Chilton's. Then you have a portable reference handy for most anything you'd need to do on the truck. You also need to check what freon your ac uses. Some of them are not to be used except by licensed shops now.
