Installation

TO INSTALL CYLINDER HEAD:

1. Clean the cylinder head and the gasket surface of the cylinder block. Clean the threads of the head bolts and bolt holes with thread chasers, and remove all foreign matter from the holes. Avoid letting debris into the cylinders or oil passages in the cylinder block.

CAUTION: Do not use a metal scraper or wire brush to clean the aluminum cylinder head. These may damage the cylinder head. Instead, use a solvent to soften carbon deposits and old sealing materials. If necessary, use a wooden or plastic scraper.

2. Check the gasket surfaces of the cylinder head and the cylinder block for warpage.
3. Place a new cylinder head gasket on the surface of the cylinder block. The word "OBEN", found imprinted on the gasket near the part number, should face up.

CAUTION: Rotating the crankshaft or the camshaft with the drive belt removed may cause interference which can damage pistons and valves.

4. Place the cylinder head in position on the cylinder block. Loosely install all the head bolts, with the special washers, then thread them in until they are finger-tight.

NOTE: To be sure of proper alignment of the installed cylinder head, place two 200 mm long, 9 mm diameter (8 in. x 3/8 in.) wooden dowels into two of the outermost head bolt holes to hold the gasket and serve as guides as the cylinder head is installed. Thread in several bolts, then remove the dowels and install the remaining bolts.

Cylinder Head Bolt Tightening Sequence:

5. Torque the bolts to 40 Nm (30 ft lb), in the sequence shown. Repeat the sequence, torquing the bolts to 60 Nm (44 ft lb). Repeat the sequence a third time, tightening each bolt an additional 1/2 turn. Alternatively, this last step may be done as two 1/4 turns.
6. Installation of the remaining parts is the reverse of removal. Reinstall the cylinder head cover with new gaskets. Check camshaft timing and reinstall the drive belt.
7. Refill the cooling system.
