Timing Component Alignment Marks: Locations
Timing Alignment
NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
Install the crankshaft sprocket with the flange facing forward.
Install the secondary timing chain onto the LH VCT assemblies. Align the colored links on the secondary timing chain with the timing marks on the VCT assemblies as shown in the illustration.
1. The timing mark on the intake VCT assembly should align between the 2 consecutive colored links.
2. The timing mark on the exhaust VCT assembly should align with the single colored link.
Install the LH primary timing chain.
- Align the colored link on the timing chain with the timing mark on the LH VCT assembly.
Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
Using the crankshaft holding tool, rotate the crankshaft clockwise until the crankshaft keyway is at the 12 o'clock position.
Install the secondary timing chain onto the RH VCT assemblies. Align the colored links on the secondary timing chain with the timing marks on the VCT assemblies as shown in the illustration.
1. The timing mark on the intake VCT assembly should align between the 2 consecutive colored links.
2. The timing mark on the exhaust VCT assembly should align with the single colored link.
Install the RH primary timing chain.
- Align the colored link on the timing chain with the timing mark on the RH VCT assembly.
Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
With the crankshaft keyway still at the 12 o'clock position, verify the timing mark alignment is correct.
