Removal of the DD13 Exhaust Gas Recirculation Cooler Water Manifold
Assembly
Remove as follows:
WARNING: PERSONAL INJURY
To avoid injury from hot surfaces, wear protective gloves, or allow engine to cool before removing
any component.
1. Shut off the engine, apply the parking brake, chock the wheels, and perform any other applicable safety steps.
2. Open the hood.
CAUTION: ELECTRICAL SHOCK
To avoid injury from electrical shock, use care when connecting battery cables. The magnetic
switch studs are at battery voltage.
3. Disconnect batteries. Refer to Original Equipment Manufacturer (OEM) procedures.
4. If needed, remove the bumper. Refer to OEM procedures.
5. If needed remove the splash shield. Refer to OEM procedures.
WARNING: FIRE HAZARD
Do not power wash or steam clean the engine bay in the area of vehicle electrical components,
unless specified by vehicle manuals or service literature. Power washing/steam cleaning can
permanently damage these components, which could result in fire, personal injury, or property
damage.
6. Steam clean the engine.
7. Drain the engine coolant. Refer to section "Cooling System Drain Procedure".
8. Remove the front air cleaner mounting bracket from the valve cover.
NOTE: Note the orientation of clamps before removal.
9. Remove the two clamps from the hot pipe. Refer to section "Removal of the Exhaust Gas Recirculation Hot Pipe".
10. Remove the hot pipe from the EGR cooler water manifold assembly and from the EGR valve and discard spherical
clamps.
11. Remove the radiator support mount.
12. Remove the two clamps from the hose connecting the coolant delivery pipe to the oil coolant module.
13. Remove the retaining strap and the two bolts from the coolant delivery pipe, then remove the coolant delivery pipe
from the engine.
14. Remove the hose clamps from the rubber connector connecting the mixer pipe to the venturi pipe.
15. Remove the mixer pipe from the cold boost pipe by removing the three bolts and one bracket bolt.
16. Disconnect the coolant outlet temperature sensor connector from the electrical wiring harness.
17. Unclip the electrical harness from the lifting eye and disconnect the Delta P harness connector.
18. Remove the EGR crossover tube and the venturi by removing the six bolts. Remove them from the engine.
19. While holding the coolant line adapter fitting with a wrench and removing the coolant line nut with a separate wrench,
remove the EGR actuator and the doser injector housing coolant lines from the EGR cooler water manifold assembly
and the doser injector housing.
20. Remove the clamps and bolts attaching the coolant feed line to the engine and remove coolant feed line.
21. Remove the exhaust manifold. Refer to section "Removal of the Exhaust Manifold".
22. Remove the coolant deaeration line from the EGR cooler water manifold assembly.
23. Remove the EGR cooler water manifold assembly by removing the nineteen bolts attaching it to the cylinder head.

Installation of the DD13 EGR Cooler Water Manifold Assembly
Install as follows:
NOTICE: Ensure the connecting tubes are lubricated with clean oil; if they are not lubricated, the tubes cannot be
fully installed or the rubber can be cut.
1. Install two new Exhaust Gas Recirculation (EGR) cooler water manifold assembly gaskets on to the EGR cooler water
manifold assembly.
2. Install the EGR cooler water manifold assembly onto the cylinder head.
3. Install and hand tighten the 17 bolts into the EGR cooler water manifold assembly. Torque the bolts to 30 N·m (22
lb·ft) in the sequence shown.

Install the EGR crossover tube. Refer to section "Installation of the Exhaust Gas Recirculation Crossover Tube".
Install the EGR venturi. Refer to section "Installation of the Exhaust Gas Recirculation Venturi".
Install the mixer pipe. Refer to section "Installation of the Mixer Pipe".
Install the exhaust manifold. Refer to section "Installation of the Exhaust Manifold".
Install the coolant delivery pipe between the EGR cooler water manifold assembly and the oil coolant module; install
two clamps onto the hose connecting the delivery pipe to the module. Torque to 3.0 to 3.5 N·m (26 to 26.5 lb·in.).
Install the retaining plate with two bolts to connect the coolant delivery pipe to the EGR cooler water manifold
assembly. Torque bolts to 20 N·m (15 lb·in.).
Install the hot pipe onto the EGR cooler water manifold assembly and the EGR valve with two new spherical clamps
and tighten clamp bolts to 12 N·m (9 lb·ft). Refer to section "Installation of the Exhaust Gas Recirculation Hot Pipe".
After installing the hot pipe from EGR cooler water manifold assembly to exhaust manifold, sweep the EGR actuator
by hand to verify it does not make contact with the clamps. If contact is made, rotate the clamps as needed to gain
clearance.
Install the doser injection valve coolant return line to the EGR cooler water manifold assembly.
• For the 5mm long thread fitting, torque to 15 N·m (11 lb·ft).
• For the 15mm long thread fitting, torque to 22 N·m (16 lb·ft).
Install the doser injection valve coolant supply line to the EGR cooler water manifold assembly.
• For the 5mm long thread fitting, torque to 15 N·m (11 lb·ft).
• For the 15mm long thread fitting, torque to 22 N·m (16 lb·ft).
Install the coolant outlet return to the EGR cooler water manifold assembly and to the EGR valve actuator.
Install the coolant deaeration line to the EGR cooler water manifold assembly.
Connect the electrical wiring harness coolant outlet temperature sensor connector.
Install the radiator support mount.
