INSTALLATION - CYLINDER HEAD(S)

RIGHT CYLINDER HEAD





CAUTION: THE CYLINDER HEAD GASKETS ARE NOT INTERCHANGEABLE BETWEEN CYLINDER HEADS AND ARE CLEARLY MARKED RIGHT OR LEFT.

The 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..

Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale the bolt must be replaced.





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 Engine Gasket Surface Preparation.

1. Clean sealing surfaces of cylinder head and block.

CAUTION: Ensure that the correct head gaskets are used and are oriented correctly on cylinder block.

NOTE: Before installing the cylinder head bolts, lubricate the threads with clean engine oil.

2. Install the cylinder head over locating dowels and finger tighten the head bolts.
3. Tighten the cylinder head bolts in the following sequence, using the 4 step torque-turn method. Tighten according to the following torque values:
- 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.

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




5. Install the inner timing cover to cylinder head bolts. Tighten bolts to 54 Nm (40 lbs.ft.).
6. Install camshaft sprocket (2) Counterhold the camshaft sprocket gear (2) and tighten the camshaft sprocket bolt to 102 Nm plus a 1/4 turn (75 lbs. ft. plus a 1/4 turn).Timing Belt & Sprockets - Installation.




7. Install the rear camshaft thrust plate (1) and seal (3) and the EGR valve.




8. Rotate the camshaft gear to it's alignment mark (1) and check the left camshaft gear (7) and crankshaft gear timing alignment marks (9).
9. Install the timing belt (4) and tensioner (12)Timing Belt & Sprockets - Installation.




10. Install the timing belt outer cover (1) . Service and Repair




11. Install the accessory drive bracket (2).




12. Install the vibration damper . Service and Repair
13. Install the accessory drive belt tensioner.
14. Install the accessory drive belt idler pulley.
