Hey Jeff,

I found this information for you.

Remove the engine front cover. For additional information, see ENGINE FRONT COVER.

Raise the vehicle.

Remove the crankshaft position (CKP) sensor and the torque converter cover.

NOTE: There is one window on the ignition pulse wheel that is unique to accept the special tool.
Install the special tool.
Turn the crankshaft to 45 degrees ATDC. The crankshaft keyway will be in the 6 o'clock position.
Install the special tool.

CAUTION: An open-end wrench must be used on the flats of the camshaft or damage to the head will occur.
Loosen the exhaust camshaft sprocket bolt.
