Cylinder Head Replacement RH

Cylinder Head RH

Removal

1. With the vehicle in NEUTRAL, position it on a hoist.

2. Remove the coolant pump bypass tube.

3. Remove the lower intake manifold. For additional information, Service and Repair

4. Remove the RH camshafts. For additional information, Service and Repair

5. Using the special tools, lower the engine until it is aligned with the A/C compressor bracket, and finger-tighten the four bolts.






6. Remove the Three-Bar Engine Support.

7. Remove the differential pressure feedback exhaust gas recirculation (EGR) sensor.
1. Disconnect the electrical connector.
2. Carefully remove the differential pressure feedback EGR sensor by sliding up and off the EGR tube.






8. Remove the three bolts and remove the differential pressure feedback EGR sensor bracket.

9. Remove the rear support brace.
1. Remove the bolt.
2. Remove the nut.
3. Remove the rear support brace.






10. Remove the RH exhaust manifold-to-pipe bolts.






11. Disconnect the Exhaust Gas Recirculation (EGR) tube from the exhaust manifold.






12. Remove the camshaft followers.






13. Remove the hydraulic lash adjusters.






14. Remove the nuts in the sequence shown and remove the exhaust manifold.
- Discard the gasket.






15. Remove the cylinder block drain plug.






16. NOTE:New cylinder head bolts must be installed. They are torque-to-yield designed and cannot be reused.

Remove the bolts in the sequence shown and remove the cylinder head.
- Discard the gasket and the bolts.






17. NOTE:The straightedge used must be flat within 0.0051 mm (0.0002 in) per foot of tool length.

Support the cylinder head on a bench with the head gasket side up. Inspect all areas of the deck face with a straightedge and feeler gauge. The cylinder head must not have depressions deeper than 0.0254 mm (0.001 in) across a 38.1 mm (1.5 in) square area, or scratches more than 0.0254 mm (0.001 in) deep.

Installation

1. Install the cylinder block drain plug.






2. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.

NOTE:New cylinder head bolts must be installed. They are torque-to-yield designed and cannot be reused.

Position the RH cylinder head, gasket and install the bolts in the sequence shown in six stages.
- Tighten the bolts in six stages.
- Stage 1: Tighten to 40 Nm (30 ft. lbs.).
- Stage 2: Tighten bolts 90 degrees.
- Stage 3: Loosen one full turn.
- Stage 4: Tighten to 40 Nm (30 ft. lbs.).
- Stage 5: Tighten 90 degrees.
- Stage 6: Tighten 90 degrees.






3. Position a new gasket and install the exhaust manifold nuts in the sequence shown.






4. Install the hydraulic lash adjusters.
- Lubricate the hydraulic lash adjusters with clean engine oil.






5. Install the camshaft followers.
- Lubricate the camshaft followers with clean engine oil.






6. Connect the EGR tube to the exhaust manifold.






7. Install the RH exhaust manifold-to-pipe bolts.






8. Install the rear support brace.
1. Install the rear support brace.
2. Install the nut.
3. Install the bolt.






9. Install the differential pressure feedback EGR sensor bracket and install the three bolts.
- Tighten to 7 Nm (62 lb-in)

10. Install the differential pressure feedback EGR sensor.
1. Carefully install the differential pressure feedback EGR sensor by sliding it on the EGR tube.
2. Connect the electrical connector.






11.Install the Three-Bar Engine Support.

12.Remove the four A/C compressor bracket bolts.






13.Using the special tools, raise the engine away from the A/C compressor bracket.
