These engines, (excluding 2.0L SPi and Zetec engines) may experience damage if the crankshaft pulley bolt is loosened during service without first installing the following Special Service Tools.
The crankshaft pulley bolt also retains the crankshaft cam drive sprocket which is NOT keyed to the crankshaft, so valve timing mayshift if the crankshaft pulley bolt is loosened. If this occurs, the pistons may contact and damage the valves.

Before ANY repair that requires loosening or removal of the crankshaft pulley bolt, engine valve timing MUST be locked by using the Special Service Tools. Do not attempt to start the engine without verifying engine cam timing.
