Cylinder Head Assembly

CYLINDER HEAD ASSEMBLY






Tighten the cylinder head bolts in the sequence shown, following this 4 step torque plus angle method. Tighten according to the following torque values:

Step 1: All 20 Nm (15 ft. lbs.).
Step 2: All 30 Nm (22 ft. lbs.).
Step 3: All + 90° Turn Do not use a torque wrench for this step.
Step 4: All an additional + 90° Turn Do not use a torque wrench for this step.

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 must be replaced.






SURFACE VARIATION

Flatness - Cylinder Head Gasket Surface less than 0.1 mm (less than 0.004 in.)
Flatness - Cylinder Block Gasket Surface less than 0.1 mm (less than 0.004 in.)





CAMSHAFT BEARING CAP






NOTE: Following the installation of each camshaft bearing cap, visually verify that the camshaft has some endplay.

Install the camshaft and camshaft bearing caps. Tighten the twelve bolts in two steps following the sequence shown:

Step 1: All 5 Nm (44 in. lbs.).
