REPAIR INSTRUCTIONS, PART 1
EGR Mixer Installation
[214 HL]
1. Inspect and clean the EGR mixer mounting
surface on the inlet manifold.
2. Assemble the EGR mixer, air heater and
gasket on the inlet manifold.
3. Using a torque wrench, tighten the screws in
a cross pattern according to specification.
EGR Venturi Housing Installation
The sequence in which the EGR venturi housing,
fuel filter valve housing, fuel lines and EECU are
assembled on the engine depends on the type of
engine stand used. For engine stands that use an
adapter plate attached to the left side of the
engine, these components cannot be installed
until after the engine has been removed from the
repair stand.
1. Assemble the venturi housing and the
venturi outlet pipe.
2. Using a torque wrench, tighten the attaching
screws according to specification.
3. Assemble the venturi housing and the outlet
pipe with a strap clamp on the cylinder block.
Do not tighten the screws.
4. Slide the coupling hose with clamps over the
ends of the crossover pipe and the venturi
housing.
5. Using a torque wrench, tighten the clamp
screws according to specification.
6. Using a torque wrench, tighten the venturi
housing and outlet pipe attaching screws to
specification.
7. Assemble the delta pressure sensors on the
housing.
8. Connect the sensors to the wiring harness.
Intermediate and Mixer Inlet Piping
Installation
[214 HL]
1. Install the intermediate pipe on its mounting
bracket. Do not tighten the clamp screws.
2. Slide the coupling hose with clamps over the
ends of the venturi outlet pipe and the
intermediate pipe. Do not tighten the clamp
screws.
3. Slide the coupling hose with clamps over the
ends of the intermediate pipe and the mixer
inlet pipe. Do not tighten the clamp screws.
4. Assemble the mixer inlet pipe on the mixer.
5. Using a torque wrench, tighten the mixer
inlet attaching screws according to
specification.
6. Using a torque wrench, tighten the bracket
clamp screws according to specification.
7. Using a torque wrench, tighten all hose
clamp screws according to specification.
EECU and Cooler Installation
[230 EK]
The sequence in which the EGR venturi housing,
fuel filter valve housing, fuel lines and EECU are
assembled on the engine depends on the type of
the engine stand used. For engine stands that
use an adapter plate attached to the left side of
the engine, these components cannot be installed
until after the engine has been removed from the
repair stand.
Fuel fresh from the tank serves as coolant for the
EECU. The cooler connects in the line carrying
the fuel from the tank into the fuel pump.
Make sure the cooling plate and EECU mating
surfaces are clean.
1. Assemble the EECU on the cylinder block.
