Variable Valve Timing Actuator Component Installation Note

WARNING: This page is about a different variant/trim than selected.

NOTE:

Identify the variable valve timing actuator as shown in the figure.

Fig 1: Identifying Variable Valve Timing Actuator

Align the alignment marks on the camshaft timing chain and both intake and exhaust side camshaft sprockets of both banks.

Fig 2: Identifying Alignment Marks On Camshaft Timing Chain And Camshaft Sprockets Of Both Banks
Install the variable valve timing actuator, camshaft timing chain and the exhaust camshaft sprocket of the RH bank as a single unit.
Remove the retaining wire inserted into the camshaft timing chain tensioner (RH).

Tool size
- TORX: T55
- TORX PLUS: 55IP
Tighten the new camshaft sprocket (RH) bolts using the appropriate tools following 4 steps.
1. Tighten to 40 N.m {4.1 kgf.m, 30 ft.lbf} .
2. Loosen 360 ° (one full turn) in reverse order.
3. Tighten to 10 N.m {102 kgf.cm, 89 in.lbf} .
4. Tighten to 90 °.
Install the variable valve timing actuator, camshaft timing chain and the exhaust camshaft sprocket of the LH bank as a single unit.
Remove the retaining wire inserted into the camshaft timing chain tensioner (LH).

Tighten the new camshaft sprocket (LH) bolts using the appropriate tools following 4 steps.
1. Tighten to 40 N.m {4.1 kgf.m, 30 ft.lbf}.
2. Loosen 360 ° (one full turn) in reverse order.
3. Tighten to 10 N.m {102 kgf.cm, 89 in.lbf} .
4. Tighten to 90 °.
Turn the crankshaft clockwise so that the crankshaft keyway is in the 11 o'clock position. (This will position the No.1 cylinder at TDC.)
