1997 Crown Victoria/Grand Marquis Workshop Manual

Engine, 4.6L (2V)

IN-VEHICLE SERVICE

Camshaft Timing Chains and Tensioners

Removal

1. CAUTION: At no time, when the timing chain(s) are removed and the cylinder heads (6049) are installed, may the crankshaft (6303) and/or camshafts (6250) be

rotated. Failure to follow these directions will result in valve and/or piston damage.

NOTE: Because this is not a free-wheeling engine, and it jumps time, there will be damage to the valves and/or pistons (6108) and will require the removal of the

cylinder heads. The camshaft sprockets (6256) should only be disassembled from the camshafts when one of the components is to be replaced.

Remove valve covers (6582) and engine front cover (6019) as described.

2. Remove crankshaft position sensor pulse wheel.

3. Rotate engine to No. 1 top dead center (TDC).
