Timing Chain Component Removal Note

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

CAUTION:

When removing the timing chain and marking the timing marks on the chain, mark the camshaft timing chain as well.

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.)

NOTE:
- Verify that there are timing marks in three locations (Yellow 1, Black 2) on the timing chain. If any timing marks are missing, mark the timing chain.
- When marking the crankshaft sprocket side timing chain, change the mark color.
- When the timing chain is replaced with a new one, mark the new timing chain at the same positions as the removed timing chain.
Mark the timing chain at the position of each timing sprocket timing mark.

NOTE:
- Verify that there are timing marks in two locations on the camshaft timing chain. If any timing marks are missing, mark the camshaft timing chain.
- If replacing with a new variable valve timing actuator, place alignment marks in the same positions as those prior to the replacement.
Mark the camshaft timing chain at the positions where it is aligned with each of the camshaft sprocket on both banks.

Remove the timing chain in the following order.
1. Chain tensioner
2. Timing chain
