Camshaft Sprocket, Variable Valve Timing Actuator (With variable valve timing mechanism) Assembly Note

1. Temporarily tighten the camshaft sprocket or variable valve timing actuator (With variable valve timing mechanism) installation bolts by hand until the timing chain is installed.

2. Fully tighten the camshaft sprocket or variable valve timing actuator (With variable valve timing mechanism) installation bolts after timing chain installation.
