Timing Drive Components: Removal

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages, coolant passages or the oil pan may cause engine failure.

NOTE: Failure to verify correct timing drive component alignment will result in severe engine damage.

Remove the engine front cover. For additional information, refer to ENGINE FRONT COVER .
Remove the LH and RH spark plugs. For additional information, refer to SPARK PLUGS .

NOTE: This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped "30RFF" (orange in color).
