9. Remove the cylinder head.
10. Remove the cylinder head gasket.
11. Inspect the cylinder head for warp using a straightedge and feeler gauge. Repair the cylinder head if necessary.
12. Installation is in the reverse order of removal.
Installation Notes:
• Ensure cylinder head bolt holes in the block are clean, dry (free of residual oil or coolant), and threads are not
damaged.
• Do not reuse the cylinder head bolts. The new bolts should be examined before use. If the bolts are stretched,
the bolts should be replaced.
• Position the new cylinder head gasket on the engine block with the part number facing up. Ensure gasket is
seated over the locating dowels in the block.
• Before installing the bolts, the threads should be lightly coated with engine oil.
• The cylinder head bolts should be installed and
torqued in the sequence shown.
• Tighten the cylinder head bolts in the following sequence.
1st Step: Tighten the bolt to 78 N·m
2nd Step: Completely loosen the bolt
3rd Step: Retighten the bolt to 20 N·m
4th Step: Tighten the bolt an additional 90°
5th Step: Finish tightening the bolt an addi-
tional 90°

Inspection
Bearing Radial Clearance
•Check the radial clearance of connecting rod bearing.
CONNECTING ROD RADIAL CLEARANCE
Radial Clearance 0.016 - 0.051 mm
Bearing Oil Clearance (Plastigauge)
•Check the oil clearance of the connecting rods and crankshaft.
Clean all engine oil off of the connecting rod bearing and the crankshaft journal.
Cut the plastigauge into lengths as wide as the crankshaft journal.
Lay the plastigauge across the crankshaft
journal.
Carefully install the connecting rod cap.
Torque the connecting rod cap nuts to 20 N·m
Carefully disassemble the connecting rod cap.
Use the measuring rule imprinted on the plas- tigauge package to measure the width of the
widest part of the plastigauge.
