Timing Components: Service Precautions

CAUTION: The timing arrows/flags on the back of the camshaft sprocket(s) are mis-marked by as much as 30° rotation. The arrows or flags should not be used for engine service procedures, including timing diagnostics.

CAUTION: The 2.5L Duratec engines are not "free-wheeling." An error in timing chain installation may result in severe valve/piston damage. Use extreme care during timing chain installation.
