Tools Required

1. Remove the powertrain assembly. Refer to Engine Replacement .

Notice: Align all timing marks before removing the timing chains, especially if you are removing only one head.

2. Remove the intake manifold. Refer to Intake Manifold Replacement .
3. Remove the camshaft covers Refer to Camshaft Cover Replacement .
4. Remove the crankshaft balancer. Refer to Crankshaft Balancer Replacement .
5. Remove the engine front cover. Refer to Engine Front Cover Replacement .
6. Remove the oil pump. Refer to Oil Pump Replacement .



7. Remove the chain tensioner from the secondary drive chain for the cylinder head being removed.
8. Remove the camshaft sprockets from the head being removed. The secondary drive chain should remain in the crankcase.



9. Remove the timing chain guides. Access to the retaining screws is through the plugs at the front of the cylinder head.
10. Remove the water crossover. Refer to Water Crossover.



11. Remove the exhaust manifold. Refer to Exhaust Manifold Replacement .
12. Remove the cylinder head M11 bolts and discard.

Notice: With the camshafts remaining in the cylinder head, some valves will be open, therefore, do not place the cylinder head on a flat surface with the valves face down. Valve damage may occur.

13. Remove the cylinder head.




Caution: Wear safety glasses when using compressed air in order to prevent eye injury.

Notice: Exercise caution when cleaning aluminum gasket surfaces in order to prevent damage to the sealing surfaces. Use only plastic, wood, or dull gasket scrapers such as J 28410. You can also use chemical agents to dissolve gasket materials. Follow the manufacturer's recommendations.

14. Remove the cylinder head gasket.
15. Clean the gasket surfaces.
16. Clean the combustion chambers.
17. Clean the head bolt holes in the crankcase with compressed air.
18. Clean the head bolt bosses in the cylinder head.

1. Ensure all the cylinder head locating pins are securely mounted in the cylinder block deck face.
2. Make sure any old thread sealant material is removed from the cylinder head bolts holes in the cylinder block.

Important: Failure to remove all the old thread sealant material from the cylinder block could cause false torque readings.

3. Install a new right cylinder head gasket using the deck face locating pins for retention.



4. Install a new left cylinder head gasket using the deck face locating pins for retention.



5. Align the cylinder head with the deck face locating pins.
6. Place the cylinder head in position on the deck face.




Important: DO NOT reuse the old M11 cylinder head bolts.

7. Install new M11 cylinder head bolts (1) in the cylinder head.
8. Install the M6 cylinder head bolts (2) at the front of the cylinder head.
9. Repeat these procedures for the remaining cylinder head.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
