    Anyone know how much the system needs. 2007 670. Can’t find a tag or sticker. Anyone know where it’s usually located?

    Thanks, found the sticker yesterday. Got it working good. Had to buy a new tap for the new self sealing cans. $8 at Harbor freight. It worked good once I figured it out. Instead of piercing the can and backing it off, you just pierce can and tighten it down, refrigerant flows. Maybe that info will help someone else. Today I charged up a Coronado glider. Looks like I’m the new A/C guy at the Shop. Lol. Boss says he’s impressed with my knowledge. Sure got him fooled. Lol. Thanks again.

    Most standard trucks now days take between 4 to 5 lbs older ones used to be between 3 to 4 as much as people might not like this if u charge .5 over or under it will still work pretty good day can go around 3 although everyone is supposed to have a sticker sometimes it gets washed off.
