Cylinder Head Torque & Sequence
A - Bank 1; B - Bank 2:
Install cylinder head follow the steps below to tighten cylinder head bolts in numerical order as shown in the figure with cylinder head bolts wrench (commercial service tool).
CAUTION:
- If cylinder head bolts reused, check their outer diameters before installation.
- Before installing cylinder head, inspect cylinder head distortion.
a. Apply new engine oil to threads and seat surfaces of cylinder head bolts.
b. Tighten all cylinder head bolts.
Torque : 98.1 N.m (10 kg-m, 72 ft-lb)
c. Completely loosen all cylinder head bolts.
Torque : 0 N.m (0 kg-m, 0 ft-lb)
CAUTION:
In step "c", loosen bolts in the reverse order of that indicated in the figure.
d. Tighten all cylinder head bolts.
Torque : 39.2 N.m (4.0 kg-m, 29 ft-lb)
e. Turn all cylinder head bolts 103 degrees clockwise (angle tightening).
CAUTION:
Check the tightening angle by using the angle wrench [SST: KV10112100 (BT8653-A)] (A). Avoid judgment by visual inspection without.
- Check tightening angle indicated on the angle wrench indicator plate.
f. Turn all cylinder head bolts 103 degrees clockwise again (angle tightening).
Re-usability
Cylinder Head Bolts Outer Diameter
- Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between (C) and (B) exceeds the limit, replace them with new one.
Limit [(C) - (B)] : 0.11 mm (0.0043 in)
- If reduction of outer diameter appears in a position other than (B), use it as (B) point.
