LML Duramax Fan Clutch Tool

A 1 7/8" wrench to loosen the fan clutch nut on a LML Duramax (mine is a 2012) and maybe other years. I made it from some scrap 7 ga. It is pretty long so I could "whack" on it above the engine and radiator. You also may not need the two extra layers welded to the sides, I put them there just to get more area on the nut. The fit is designed to be tight, I polished the inside edges with a flap disk until it fit as I wanted.
