Cylinder Head Assembly

LEFT CYLINDER HEAD









Tighten the bolts in sequence using the following steps and torque values:

Step 1: Tighten bolts 1-8 27 Nm (20 ft. lbs.)
Step 2: Verify that bolts 1-8 all reached 27 Nm (20 ft. lbs.)
By repeating step-1 without loosening the bolts.
Tighten bolts 9 through 12 14 Nm (10 ft. lbs.)

Step 3: Tighten bolts 1-8 90 degrees
Step 4: Tighten bolts 1-8 90 degrees, again.
Tighten bolts 9-12 26 Nm (19 ft. lbs.)






RIGHT CYLINDER HEAD









Tighten the bolts in sequence using the following steps and torque values:

Step 1: Tighten bolts 1-8 27 Nm (20 ft. lbs.).
Step 2: Verify that bolts 1-8 all reached 27 Nm (20 ft. lbs.), by repeating step 1 without loosening the bolts.
Step 3: Tighten bolts 9 thru 12 14 Nm (10 ft. lbs.).
Step 4: Tighten bolts 1-8 90 °.
Step 5: Tighten bolts 1-8 90 °, again.
Step 6: Tighten bolts 9-12 26 Nm (19 ft. lbs.)

BOLT RE-USABILITY









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 should be replaced.






SURFACE VARIATION

If measurements exceed 0.0508 mm (0.002 in.) replace the cylinder head.






CAMSHAFT BEARING CAP






Tighten the camshaft bearing cap retaining bolts 11 Nm (100 in. lbs.)
