    Q:
    How should you handle the camshaft sprocket bolts for the Timing Chain Tensioner on the 2002 Ford Ranger? Posted by Antwine H.
    A:
    Loosen both camshaft sprocket bolts but don't remove them. Use a wrench on the hexagonal area of the camshaft to hold it while turning the camshaft sprocket bolt. Note that the hexagonal portion of the camshaft is located just after the second lobe from the front. Caution: Damage to the valves or pistons may occur if the camshafts are rotated during this procedure. You can Select Your Vehicle to see complete installation and repair tips.
