Cylinder head












Tighten cylinder head bolts in numerical order as shown.

a. Apply new engine oil to threads and seating surfaces of bolts.
b.Tighten all bolts.

Cylinder head bolts: 40.0 Nm (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.

Cylinder head bolts: 0 Nm (0 kg-m, 0 ft-lb)

CAUTION: In this step, loosen bolts in reverse order of that indicated as shown.

e.Tighten all bolts.

Cylinder head bolts: 40.0 Nm (4.1 kg-m, 30 ft-lb)

f.Turn all bolts 75 degrees clockwise (angle tightening).

g.Turn all bolts 75 degrees clockwise again (angle tightening).

Re-usability

CAUTION: If cylinder head bolts are reused, check their outer diameters before installation.



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.
