Cylinder Head

Tighten cylinder head bolts in numerical order as shown with the following procedure to install cylinder head.









CAUTION:
If cylinder head bolts are re-used, check their outer diameters before installation. Follow the "Cylinder Head Bolts Outer Diameter" measurement procedure.
a. Apply new engine oil to threads and seating surfaces of bolts.
b. Tighten all bolts in the specified order.

: 40.0 N.m (4.1 kg-m, 30 ft-lb)






c. Turn all bolts 60 degrees clockwise (angle tightening) using Tool (A) in the specified order.

CAUTION:
Check and confirm the tightening angle by using Tool (A) or protractor. Avoid judgment by visual inspection without the tool.

Tool number : KV10112100 (BT-8653-A)

d. Completely loosen all bolts in reverse order.

: 0 N.m (0 kg-m, 0 ft-lb)


CAUTION:
In this step, loosen bolts in reverse order of that indicated.
e. Tighten all bolts in the specified order.

: 40.0 N.m (4.1 kg-m, 30 ft-lb)





f. Turn all bolts 75 degrees clockwise (angle tightening) using Tool (A) in the specified order.

CAUTION:
Check and confirm the tightening angle by using Tool (A) or protractor. Avoid judgment by visual inspection without the tool.

Tool number : KV10112100 (BT-8653-A)

g. Turn all bolts 75 degrees clockwise again (angle tightening) using Tool (A) in the specified order.

CAUTION:
Check and confirm the tightening angle by using Tool (A) or protractor. Avoid judgment by visual inspection without the tool.

Re-usability

Cylinder Head Bolts Outer Diameter
- Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between "d1" and "d2" exceeds the limit, replace them with a new one.

Limit [(d1) - (d2)]: 0.15 mm (0.0059 in)

- If reduction of outer diameter appears in a position other than "d2", use it as "d2" point.




Camshaft Bearing Cap Torque & Sequence

a. Tighten No. 9 to 11 in numerical order.

Camshaft bracket bolts (9 - 11) : 1.96 N.m (0.20 kg-m, 17 in-lb)

b. Tighten No. 1 to 8 in numerical order.

Camshaft bracket bolts (1 - 8) : 1.96 N.m (0.20 kg-m, 17 in-lb)

c. Tighten all bolts in numerical order.

Camshaft bracket bolts (all) : 5.88 N.m (0.60 kg-m, 52 in-lb)

d. Tighten all bolts in numerical order.

Camshaft bracket bolts (all) : 10.4 N.m (1.1 kg-m, 8 ft-lb)
