Cylinder Head - LH: Installation

NOTE: 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.

Install a new gasket, the LH cylinder head and 8 new bolts. Tighten the bolts in the sequence shown in illustration below 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.
- Stage 5: Tighten 45 degrees.

NOTE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

Using new intake manifold and thermostat housing gaskets, install the lower intake manifold and the 10 bolts.
- Tighten in the sequence shown in illustration to 10 Nm (89 lb-in).
