Just a quick video on how to use two wrenches together to increase leverage and loosen a bolt. It’s an old mechanic’s trick, but a good one! It can really save you if the bolt is hard to access or you can’t get a breaker-bar and a socket in on it. I’ve used this trick a lot working on trucks when I get into spaces that no ratchet will fit into.
You can also use this trick to tighten a bolt, just flip the second wrench to the other prong of the first wrench (mirror image of the loosening position) and tighten away.
I originally uploaded this video a couple years ago, but recently I went back and did some re-editing to clean it up and add some more information.
