Cylinder Head, Removal

(With VEB or EPG; also with coolant drained off)

(See also “Cylinder Head, Overhaul” page 27.)

You must read and understand the precautions and

guidelines in Service Information, group 21, "General

Safety Practices" before performing this procedure.

If you are not properly trained and certified in this

procedure, ask your supervisor for training before

you perform it.

CAUTION

Observe the greatest possible cleanliness when

working on the cylinder head. Dirt particles in the

fuel and oil channels can cause the unit injectors to

malfunction, and can cause the VEB (if equipped)

to fail or cause engine damage.

Note: The exhaust manifold can remain in place when

removing the cylinder head. Remove the three bolts

holding the thermostat housing. Then, turn the housing

back out of the way to allow enough clearance to remove

the head.

Note: Do not leave the unit injector tubes open with the

injectors removed. Install protective plugs 9998251 to

protect tubes from contaminants.

Special tools: 9996966, 9998249, 9998251,

Remove the electrical wires from the preheater (if

equipped) and the intake manifold sensor and harness

from the intake manifold. If the engine is equipped with

VEB, remove the oil supply pipe. Plug both of the oil

holes in the cylinder head and block.
