: Rotate the crankshaft pulley clockwise until the timing mark aligns with "0" on the lower timing cover. Ensure the "5A" or "E" hole mark on the camshaft pulley aligns perfectly with the matching mark on the bearing cap.

Loosen the alternator and power steering belts, then remove them.

Inspect all vacuum hoses connected to the intake manifold for cracks or disconnection.
