Gradually loosen cylinder head bolts (12) in reverse numerical order from (10) through (1) from cylinder head (11). Remove cylinder head bolts (12) from cylinder head (11) and discard.
Attach a suitable lifting device to cylinder head (11). The weight of cylinder head (11) is approximately 46 kg (100 lb).
Use the suitable lifting device to lift cylinder head (11) off the cylinder block.
Place the cylinder head on a surface that will not scratch the face of the cylinder head.

Notice the number of notches in Area (A). Refer to Illustration 5 and Illustration 6.
Thoroughly clean the gasket surfaces of the cylinder head and the cylinder block. Do not damage the gasket surfaces of the cylinder head of the cylinder block. Ensure that no debris enters the cylinder bores, the coolant passages, or the lubricant passages.
Inspect the dowels for damage. If necessary, replace the dowels in the cylinder block.
Inspect the gasket surface of the cylinder head for distortion. Refer to Specifications, "Cylinder Head" for more information. If the gasket surface of the cylinder head is distorted beyond maximum permitted limits, replace the cylinder head.
Notice the location of the cylinder head gasket notches in area (A) and refer to Table 1. Align new cylinder head gasket (13) with the dowels.

Use a suitable lifting device to lift cylinder head (11). The weight of cylinder head (11) is approximately 46 kg (100 lb).
Align cylinder head (11) with the cylinder block. Install cylinder head (11) to the cylinder block.Note: Ensure that the cylinder head is correctly positioned on the dowels.
Lubricate the threads and the shoulder of new cylinder head bolts (12) with engine oil.
Install new cylinder head bolts (12) in numerical order from (1) through (10) to cylinder head (11).
Tighten the new cylinder head bolts according to the following procedure.
Tighten bolts (1) through (10) to a torque of 35 N m (26 lb ft)
Tighten bolts (1) through (10) to a torque of 108 N m (80 lb ft)
Tighten bolts (1) through (10) to a torque of 165 5 N m (122 4 lb ft)
Fill the cooling system with coolant. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct filling procedur
