ISSUE
Some 2001-2007 MY vehicles equipped with a 2.0L or 2.3L Duratec Engine may exhibit no start, loss of engine timing or scraping noise at crankshaft
pulley at front of engine. These engines, (excludes 2.0L SPI and Zetec engines) may experience engine damage if the crankshaft pulley bolt is loosened
during service WITHOUT FIRST INSTALLING THE SPECIAL SERVICE TOOLS PER THE WORKSHOP MANUAL PROCEDURE. The
crankshaft pulley bolt also retains the crankshaft cam drive sprocket which is NOT keyed to the crankshaft, so valve timing may shift if the crankshaft
pulley bolt is loosened. If this occurs, the pistons may contact and damage the valves.
ACTION
Before ANY repair requiring loosening or removal of the crankshafl pulley bolt, engine valve timing MUST be locked by the Special Service Tools
identified in the online Workshop Manual, Section 303-01 (In-Vehicle Repair: Crankshaft Pulley). Do not attempt to start the engine without verifying
engine cam timing.
SERVICE PROCEDURE

FAILURE TO FOLLOW THE PROCEDURE EXACTLY CAN RESULT IN SERIOUS ENGINE DAMAGE.
