2 Description and Operation of the DD13 Exhaust Gas Recirculation
Valve Actuator

The Exhaust Gas Recirculation (EGR) system is controlled by the Motor Control Module (MCM) via a CAN signal which
controls the EGR valve actuator. The EGR valve actuator then opens and closes the EGR valve to achieve the desired flow
through the EGR cooler where the high temperature gas is cooled and then directed through the mixing pipe where it is
mixed with air from the Charge Air Cooler (CAC) and directed into the cylinders.

When production of the DD13 began, a Delphi® actuator was utilized. Beginning with engine serial number HDE108907,
the Sonceboz® actuator was introduced. Both actuators work the same, but are not interchangeable.

3 Removal of the DD13 Exhaust Gas Recirculation Valve Actuator

Remove as follows:

NOTE: The clamping bolt and actuator rod must remain installed to the actuator linkage when removing or
installing the lock nut to avoid damage to the actuator valve gears.

1. Drain the coolant. Refer to section "Cooling System Drain Procedure",
2. Remove one nut connecting the Exhaust Gas Recirculation (EGR) valve actuator to the linkage and remove linkage
from the actuator.

NOTICE: To prevent damage to the coolant inlet and outlet lines, hold the coolant line fittings with a wrench
during line removal. . :

3. Remove the coolant line from the EGR valve actuator and cylinder block,
4. Remove the coolant fine from the EGR valve actuator and water manifold.
5. Disconnect the EGR valve actuator electrical harness connector from the engine electrical harness.
6. Remove the EGR valve actuator from the cylinder block.
a. For the Delphi actuator, remove three bolts and spacers from EGR valve actuator and remove actuator from the
cylinder block.
b. For the Sonceboz actuator, remove the three bolts from the EGR valve actuator and remove actuator from the
cylinder block,

4 Installation of the DD13 Exhaust Gas Recirculation Valve Actuator

4 Installation of the DD13 Exhaust Gas Recirculation Valve Actuator

Install as follows:

NOTICE: If reusing the original Exhaust Gas Recirculation (EGR) valve actuator bracket bolts, always apply a
small amount of copper-based anti-seize compound to the bolts. The original coating will burn off and that makes
it necessary to reapply the anti-seize compound.

NOTICE: Ensure the bracket and exhaust manifold are at ambient temperature when the actuator bracket bolts
are torqued. §

NOTICE: Do not turn on the ignition power until all of the installation steps are completed.

4. Install the EGR valve actuator to cylinder block.
a. For the Delphi actuator, install the EGR valve actuator to cylinder block with the bolts and two spacers. Torque
bolts to 30 Nem (22 Ibeft).
b. For the Sonceboz actuator, install the EGR valve actuator to cylinder block with the bolts. Torque bolts to 30
Nem (22 Ibeft).
2. Install the EGR valve actuator rod onto the actuator. Apply a small amount of copper based anti-seize compound to the
nut threads and tighten. Torque nut to 20 Nem (15 Ibeft).

NOTICE: To prevent damage to the coolant inlet and outlet lines, hold the coolant line fittings with a wrench
during line installation. :

3. Install the coolant line to the EGR valve actuator and fitting on cylinder block. Tighten coolant line to EGR valve
actuator to 25 Nem (18 Ibeft). Tighten coolant line to fitting on cylinder block 40 Nem (29 Ibeft),

4. Install the coolant line to the EGR valve actuator and water manifold. Tighten coolant line to 35 N-m (26 lb-ft).

5. Connect the EGR valve actuator to the engine wiring harness.

6. Fill the coolant system. Refer to section "Cooling System Fill Procedure".
