4. Remove the bolt securing the exhaust crossover pipe to the cylinder head.
5. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



6. Remove the bolt (1) securing the front transaxle brace (2) to the cylinder head.
7. Loosen the bolts (3) attaching the transaxle brace (2) to the transaxle.



8. Remove the bolt (2) securing the rear transaxle brace (1) to the transaxle.
9. Lower the vehicle.
10. Remove the nuts (3) securing the rear transaxle brace (1) to the cylinder head.
11. Remove the rear transaxle brace.



12. Remove the 3 M6 external drive bolts from the front portion of the cylinder head.

Important: DO NOT reuse the M11 cylinder head bolts.

13. Remove and discard the ten M11 internal drive cylinder head bolts.



14. Remove the right cylinder head. Make sure that no dowel guide pins are stuck in the cylinder head.

Important: You must clean the thread sealant material from the cylinder head bolt holes in the cylinder block. Failure to do so could cause false torque readings during reassembly.

15. After removing the cylinder head, remove any remaining bolt thread sealant material from the threaded cylinder block holes.




Important: DO NOT reuse the cylinder head gasket.

16. Remove the right cylinder head gasket.
17. Remove all remaining gasket material from the cylinder head and cylinder block using the J 28410 .
18. Place the cylinder head on a flat, clean surface with the combustion chambers face-up in order to prevent damage to the deck face.
19. Clean and inspect the cylinder head. Refer to Cylinder Head Cleaning and Inspection in Engine Mechanical - 4.6L Unit Repair.

1. Make sure all the cylinder head locating pins are securely mounted in the cylinder block deck face.

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

2. Make sure any old thread sealant material is removed from the cylinder head bolt holes in the cylinder block.



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



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




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

6. Install new M11 cylinder head bolts in the cylinder head.
7. Install the M6 cylinder head bolts at the front of the 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.

8. Tighten the right cylinder head bolts in the sequence shown.

8.3.	Third Pass

Tighten
Repeat the sequence turning each bolt another 60 degrees.

8.4.	Final Pass

Tighten
Repeat the sequence again turning each bolt a final 45 degrees (total 175 degrees).

9. Tighten the M6 bolts at the front of the cylinder head.

Tighten
Tighten the M6 cylinder head bolts to 12 N·m (106 lb in).




10. Position the rear transaxle brace over the studs located at the rear of the right cylinder head.
11. Loosely install the nuts (3) securing the rear transaxle brace (1) to the cylinder head.
12. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
13. Install the bolt (2) securing the rear transaxle brace (1) to the transaxle.

Tighten
Tighten the rear transaxle brace bolt to 50 N·m (37 lb ft).




14. Install the bolt (1) securing the front transaxle brace (2) to the cylinder head.

Tighten
