REMOVAL
1. Remove the engine and transaxle assembly.
2. Remove the timing chain.
3. Remove the camshafts.
4. Remove spark plugs.





5. Remove cylinder head loosening bolts in the order as shown, using power tool.
6. If necessary to transfer to new cylinder head or remove for reconditioning, remove the intake manifold collector, intake manifold, and fuel tube assembly.

INSPECTION AFTER REMOVAL

Outer Diameter of Cylinder Head Bolts





^ Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between d1 and d2 exceeds the limit, replace the bolts with new ones.
Limit (d1 - d2): 0.23 mm (0.0091 in) or less
^ If reduction of outer diameter appears in a position other than d2, use it as d2 point.

INSTALLATION
1. Install a new cylinder head gasket.





2. Follow the steps below to tighten the cylinder head bolts in the numerical order as shown.

CAUTION:
^ If cylinder head bolts are re-used, check their outer diameters before installation. Follow the "Outer Diameter of Cylinder Head Bolts" measurement procedure.

Step a: 98.1 Nm (10 kg-m, 72 ft-lb)
Step b: Loosen to 0 Nm in the reverse order of tightening.
Step c: 39.2 Nm (4.0 kg-m, 29 ft-lb)
Step d: 75° clockwise
Step e: 75° clockwise








^ Apply new engine oil to the threads and the seating surfaces of bolts.

CAUTION: Check and confirm the tightening angle by using angle wrench or protractor. Avoid judgment by visual inspection without the tool.
