Sienna FWD V6-3.5L (2GR-FE) (2009)
HINT
When the engine is correctly timed, the timing marks will NOT perfectly align.
HINT
If the timing marks appear vastly out of alignment, turn the crankshaft one revolution (360°) clockwise and note the position of the timing marks.
Component Removal Guidelines
1.
If engine disassembly is required that involves removing the camshafts or timing gears set the # 1 cylinder to TDC compression wipe away any oil
and mark the following items in relation to each other prior to disassembly:
^
Timing gears
^
Timing chain
^
Timing chain No. 2
NOTE
This relationship MUST be maintained. The intake gear is timed in relation to the crankshaft via the timing chain; the exhaust gear is timed in
relation to the intake gear via the No. 2 timing chain.
2.
If NEW camshaft timing gears or the No. 2 timing chain are being installed the two yellow links on the No. 2 timing chain can be used to ensure
correct relationship between the intake timing gear and the exhaust timing gear.
