Cylinder Head - LH





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.

NOTE: If the cylinder head is replaced, a new secondary timing chain tensioner will need to be installed.

NOTE: The valve tappets must be installed in their original positions. Coat the valve tappets with clean engine oil prior to installation.

1. NOTE: If the cylinder head is replaced, a new secondary timing chain tensioner will need to be installed.
Install a new gasket, the LH cylinder head and 8 new bolts. Tighten in the sequence shown in 5 stages:

- Stage 1: Tighten to 20 Nm (177 lb-in).

- Stage 2: Tighten to 35 Nm (26 lb-ft).

- Stage 3: Tighten 90 degrees.

- Stage 4: Tighten 90 degrees

- Tighten the block heater to 40 Nm (30 lb-ft).






9. Using a new gasket, install the RH catalytic converter and 4 new nuts.
- Tighten to 40 Nm (30 lb-ft).






10. Install the LH cylinder block drain plug.
- Tighten to 16 Nm (142 lb-in) plus an additional 180 degrees.






11. Install 6 new LH exhaust manifold studs.
- Tighten to 12 Nm (106 lb-in).






12. Using a new gasket, install the LH catalytic converter and 3 new lower LH catalytic converter manifold-to-cylinder head nuts.
- Install the 3 new upper LH catalytic converter manifold-to-cylinder head nuts and tighten to 25 Nm (18 lb-ft).

- Tighten the 3 lower LH catalytic converter manifold-to-cylinder head nuts to 25 Nm (18 lb-ft).






13. Install the LH exhaust heat shield and the 3 bolts.
- Tighten to 12 Nm (106 lb-in).






14. NOTE: Apply anti-seize to the threads of the HO2S (Heated Oxygen Sensor) prior to installing.
