Accessing bolts in the engine bay can be a lot like trying to make your way across a crowded nightclub. Components often enjoy socializing close together leaving little room to turn a wrench.
Instructables DIYer, Toga_Dan, found himself in a tight spot while working under the hood and couldn’t get enough torque on his wrench. There wasn’t enough room for a cheater bar or to even swing a hammer. His solution? Use an old bicycle chain and string it through the closed end of a combination wrench and then loop it through the hole of a barbell weight and secure with vice grips. With the open end of the wrench on the nut or bolt, hammer away at the hanging weight which will pull on the chain, turning the wrench.
