Gasket - Cylinder Head - RH
12.29.03 Gasket - cylinder head - RHBefore disconnecting the battery, ensure all text and cautions in the battery disconnection information are observed.
Remove
1. Position vehicle on lift.
2. Disconnect battery earth lead.
3. Drain cooling system.
4. Drain engine oil and remove oil filter.
5. Remove RH exhaust manifold.
6. Remove coolant pump to coolant manifold pipes.
7. Remove RH VCC unit.
8. Fit LRT-12-226 to VCC solenoid and remove solenoid.
CAUTION: Do not allow oil to come into contact with the drive belts while removing the solenoid.
9. Remove LRT-12-227 from timing tool access hole.
10. Rotate engine crankshaft pulley anti-clockwise to align the 450 before TDC timing mark.
NOTE: Raise timing chain and hold under tension while turning crankshaft pulley.
11. Remove LRT-12-223/5, LRT-12-223/6, LRT-12-223/2 and LRT-12-223/1 from RH cylinder head camshafts.
12. Working in the sequence shown, progressively loosen 10 cylinder head bolts.
13. Discard 10 cylinder head bolts and remove 10 cylinder head bolt washers.
14. With assistance, remove cylinder head assembly.
15. Discard cylinder head gasket.
16. Discard O-ring from cylinder block.
Refit
1. Clean mating faces of cylinder head and cylinder block, dowels and dowel holes. If necessary remove all traces of sealing compound with hard wood scraper. Ensure remnants do not remain in oil ways cooling ducts or bolt holes.
CAUTION: Make sure no oil or coolant is left in the cylinder head bolt holes as damage to the cylinder block may occur when tightening the cylinder head bolts.
2. Using a straight edge and feeler gauges, check cylinder head for distortion along lines in illustration.
3. Fit new"O" ring to cylinder block.
4. Apply sealant, Part No. STC 50550 to areas illustrated.
5. Fit new cylinder head gasket to locating dowels on cylinder block.
6. With assistance, fit cylinder head and carefully position cylinder head onto dowels.
7. Fit cylinder head bolt washers and new cylinder head bolts. Tighten cylinder head bolts in sequence shown to 30 Nm (22 ft. lbs.). Using an angle torque gauge tighten all bolts in sequence by a further 80° and then a final 80�.
NOTE: Do not remove special coating from new cylinder head bolts.
8. Carefully rotate camshafts until letter and cylinder number markings located on rear of camshafts are in an upright position.
NOTE: The twisting and apparent misalignment of the camshafts does not indicate incorrect engine timing.
9. Loosen bolt securing LRT-12-223/2 to LRT-12-223/1.
10. Fit LRT-12-223/2 and LRT-12-223/1 to rear of RH camshafts and tighten bolt securing tools.
11. Fit LRT-12-223/5, LRT-12-223/6 to RH cylinder head and tighten LRT-12-223/6 into spark plug thread.
12. Rotate engine crankshaft pulley clockwise to align TDC timing mark.
NOTE: Raise timing chain and hold under tension while turning crankshaft pulley.
13. Position LRT-12-227 through timing tool access hole and secure flywheel in TDC position.
14. Fit LRT-12-226 to VCC solenoid and fit solenoid.
15. Fit RH VCC unit.
16. Fit coolant pump to coolant manifold pipes.
17. Fit RH exhaust manifold.
18. Fit new oil filter and fill engine with oil.
19. Fill cooling system.
20. Connect battery earth lead.
