Left Cylinder Head

LEFT CYLINDER HEAD

CAUTION: When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use ONLY a wooden or plastic scraper.





1. Clean sealing surfaces of cylinder head and block Engine Gasket Surface Preparation.

CAUTION: The cylinder head gaskets are not interchangeable between cylinder heads and are clearly marked right or left.

2. Install head gasket over locating dowels. Ensure the gasket is installed on the correct side of engine.






CAUTION: Cylinder head bolts are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced. Failure to replace a damaged bolt may lead to possible engine damage.

3. inspect the cylinder head bolts (1 and 4) for straightness, head damage, thread damage and necking. Necking can be checked by holding a scale or straight edge against the threads (3). If all the threads do not contact the scale evenly (2) the bolt must be replaced.
4. Install the cylinder head over locating dowels.

NOTE: Lightly lubricate the threads of the cylinder head bolts with clean engine oil prior to installation.

5. Install the cylinder head bolts finger tight.





6. Tighten the cylinder head bolts in the sequence shown using the following 4 step torque-turn method:
- Step 1: All to 61 Nm (45 ft. lbs.)
- Step 2: All to 88 Nm (65 ft. lbs.)
- Step 3: All (again) to 88 Nm (65 ft. lbs.)
- Step 4: + 90° Turn Do not use a torque wrench for this step.

7. Bolt torque after 90° turn should be over 122 Nm (90 ft. lbs.) in the tighten direction. If not, replace the bolt.










8. Install the inner timing cover to cylinder head bolts. Tighten bolts to 54 Nm (40 lbs.ft.).





9. Apply light coat of clean engine oil to the lip of the camshaft oil seal (3) and Seal Protector Sleeve 6788 (2).

NOTE: When installing the camshaft into the cylinder head , you must first insert the seal protector through the camshaft seal until the camshaft seats, then remove Seal Protector Sleeve 6788 from the camshaft.

10. Install the oil seal onto the camshaft (1) using Seal Protector Sleeve 6788 and install the camshaft into the cylinder head (4).





11. Install camshaft sprocket. Hold the camshaft sprocket gear and tighten the camshaft sprocket bolt to 115 Nm plus a 1/4 turn (85 lbs. ft. plus a 1/4 turn) Timing Belt & Sprockets - Installation.





12. Install the rear camshaft thrust plate (1).





13. Rotate the left camshaft gear to the alignment mark (1) on rear timing belt cover. Check the right camshaft gear and crankshaft gear timing alignment marks (1 and 2).
14. Install the timing belt Timing Belt & Sprockets - Installation.
15. Install the tensioner Tensioner.





16. Install the timing belt front covers (1, 2 and 3) Engine Timing Cover(s) - Installation.
17. Install the power steering reservoir.





18. Install the vibration damper (5) Vibration Damper - Installation.
19. Install the upper engine mount Engine Mount Insulator - Installation.
20. Install the accessory drive belt tensioner (6).
21. Install the lower accessory drive belt idler pulley (2).
22. Install the left exhaust manifold Exhaust Manifold - Installation.
23. Install the exhaust cross over pipe Exhaust Manifold - Installation.





24. Install the left rocker arm assembly (2) Valve Rocker Arm - Installation.
25. Install the left cylinder head cover and ground strap.





26. Install lower intake manifold (1) and gasket (2) Intake Manifold - Installation.





27. Install the fuel rail Fuel Rail - Installation.





28. Install the upper intake manifold Intake Manifold - Installation.





29. Connect the fuel line (1) to the fuel rail.
30. Install the radiator cooling fan assembly Cooling Fan - Installation.
31. Install the radiator core support.
32. Install the radiator close out panel.





33. Install the air cleaner housing Air Cleaner Body - Installation.
34. Install the engine cover.
35. Fill the coolant system.





36. Connect the negative battery cable (1).
