Ford 2.3/2.0L Duratec Cam Timing

Some 2001-2007 vehicles equipped with a Ford 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.

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.

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.
