INSPECTION
Use a straightedge and feeler gauge to check the
flatness of the engine cylinder head and block mating
surfaces.
The minimum cylinder head thickness is 89.95mm
(3.541 in.).
INSTALLATION
CAUTION: Piston protrusion must be measured to
determine cylinder head gasket thickness if one or
more cylinder liners have benn replaced (Refer to 9
- ENGINE/CYLINDER HEAD - STANDARD PROCE-
DURE).
NOTE: If cylinder liner(s) have not been removed,
the same thickness head gasket that was removed
can be used.(1) Clean and inspect gasket mating surfaces.
(2) Position correct head gasket on engine block.
(3) Place cylinder head on engine block (Fig. 19).
CAUTION: New cylinder head bolts must be uesd.
(4) Tighten cylinder head bolts following procedure
below.
Cylinder Head Bolt Torquing Procedure
(1) Lubricate cylinder head bolts with engine oil.
(2) Torque bolts to 30N´m in numerical starting
with bolt #1 (Fig. 20).
(3) Tighten all bolts an additional 50É, starting
with bolt #4 then 5-6-7-8-9-10-1-2-3-11-12-13-14-15-
16-17-18 (Fig. 20).
(4) Finally tighten all bolts an additional 75É in
numerical order starting with bolt #1 (Fig. 20).
(5) Slide exhaust manifold and turbocharger on
exhaust manifold studs (Fig. 18).
(6) Install exhaust manifold retaining nuts. Torque
nuts to 32.4N´m.
(7) Install exhaust manifold heat shield (Fig. 18).
Torque bolts to 27.5N´m.
(8) Install turbocharger outlet to charge air cooler
pipe (Fig. 17).
(9) Install thermostat housing to upper radiator
hose pipe (Fig. 17). Install retaining bolt and torque
to 47.1N´m.
(10) Install coolant recovery pressure container
(Refer to 7 - COOLING/ENGINE/COOLANT RECOV-
ERY PRESS CONTAINER - INSTALLATION).
