cylinder block.
28. If the dipstick hose is attached to the intake throttle valve bracket, remove the clip attaching it.
WARNING: PERSONAL INJURY
To avoid injury when removing or installing a heavy engine component, ensure the component is
properly supported and securely attached to an adequate lifting device to prevent the component
from falling.

Installation of the DD13 Cylinder Head

Install as follows:
NOTICE: Thoroughly clean counter bores with a wire brush to remove any foreign material before installation of
head gasket. Failure to properly clean counter bores may result in head gasket failure.
1. Inspect the head bolt holes in both block and head for the presence of oil, water, dirt, or damaged threads. Clean or retap as necessary. Ensure piston domes, cylinder head, and cylinder block fire deck surfaces are clean and free of foreign
matter.

2. Install four lift hooks onto the cylinder head.
WARNING: PERSONAL INJURY
To avoid injury when removing or installing a heavy engine component, ensure the component is
properly supported and securely attached to an adequate lifting device to prevent the component
from falling.

WARNING: PERSONAL INJURY
To avoid injury, never remove any engine component while the engine is running.

3. Lift the cylinder head using tool (W470589006200) so the cylinder head can hang at a 30-45 degree angle longitude for
10 minutes. The oil and coolant will need to drain before the head can be installed on the engine.
4. Verify that the cylinder liner protrusion heights are within specification prior to installing the cylinder head. Refer to
section "Installation of the Cylinder Liner" for cylinder liner protrusion specifications.
5. Alternate the cylinder head to hang in the opposite direction at the same angle for ten minutes.
6. Install cylinder head guide studs (W471589016100).

3 Installation of the DD13 Cylinder Head

NOTE: Be sure both fire decks on the block and head surfaces are clean and dry, especially in the grommet
areas.
7. Position a new cylinder head gasket onto the cylinder block.
8. Lift the cylinder head into position using cylinder head/engine lifting bar tool (W470589006200). Lower cylinder head
into place over the guide studs and dowel pins until it is seated on the engine block.
9. Remove the guide studs.
10. Remove the lifting hooks from the cylinder head.
NOTICE: Do not dip the entire cylinder head mounting bolts in oil as it could provide too much oil causing
improper torque results.
11. Coat the threads and underside of bolt heads with clean engine oil before installation.
12. Install the 40 cylinder head bolts into the cylinder head using the torque sequence shown below. Torque bolts (1
through 38) in three steps as follows:
a. 200 N·m (147 lb·ft).
b. 90° torque turn.
c. 90° torque turn.
13. Using the torque sequence shown, torque the small bolts (39 and 40) to 60 N·m (44 lb·ft).
