procedure to reset 2012 ford edge timing reset on 3.5 engine you have to set the crankshaft key to the right position using a mark on the tooth of the sprocket as you can see on my video, make sure the camshaft is also on the right position and the mark on the chain most aligned with the sprocket mark on both sides of the top cylinder, without the chain and marks on the sprocket aligning together you can never get a smooth drive, you can follow the steps on this video and you are good to go.
