1. Remove the valve cover(s) for the cylinders being serviced.
2. Locate the dowel hole in the vibration damper.

The hole is located between 2 of the 4 bolts that attach the damper to the front of the crankshaft.
3. NOTE: For vehicles with a single generator, use a long arm box wrench to rotate the engine. Use an inspection mirror to verify that the dowel
hole is in the 12 o'clock position.
Rotate the crankshaft until the dowel hole is at the 12 o'clock position.

The No. 1 piston should be on the compression stroke. Wiggle the rocker on the No. 1 cylinder to verify both intake and exhaust rocker arms
