DODGE RAM SRT-10 2006 Service Repair Manual

3. Install NVLD filter (2) and nut (1).
4. Carefully install vapor/vacuum lines, and fuel tubes/
lines (1) to each EVAP canister. Install bolts (6).
5.The vapor/vacuum lines and hoses must be
firmly connected. Also check the vapor/vacuum
lines at the NVLD Pump, LDP, LDP filter and
EVAP canister purge solenoid for damage or
leaks. If a leak is present, a Diagnostic Trouble
Code (DTC) may be set.
6. If necessary, install skid plate(s).

VALVE-EGR
DESCRIPTION
4.7L Engine
The electronic EGR valve and solenoid assembly (3)
is attached to the rear of the left cylinder head. An
exhaust gas routing tube (1) connects the EGR valve
to the intake manifold.
5.7L Engine
The electronic EGR valve and solenoid assembly (2)
is attached to the front of the right cylinder head. An
exhaust gas routing tube (4) connects the EGR valve
to the intake manifold.
OPERATION
Exhaust gas recirculation flow is determined by the Powertrain Control Module (PCM) and is controlled by an elec-
tronic EGR valve assembly. For a given set of conditions, the PCM knows the ideal exhaust gas recirculation flow
to optimize NOx and fuel economy as a function of the pintle position. Pintle position is obtained from the position
sensor. The PCM adjusts the duty cycle of 128 Hz power supplied to the solenoid coil to obtain the correct position.
The electronic EGR valve assembly consists of a pintle, valve seat, and housing which contains and regulates
exhaust gas flow. An armature, return spring, and solenoid coil provide the operating force to regulate exhaust gas

flow by changing the pintle position. The solenoid coil assembly is wired in parallel with a diode that connects two
internal connectors.
REMOVAL
4.7L
The electronic EGR valve and solenoid assembly (4)
is attached to the rear of the left cylinder head. An
exhaust gas routing tube (3) connects the EGR valve
to the intake manifold.
1. Remove electrical connector (5) at top of EGR
valve solenoid.
2. Remove tube mounting bolt (1) at intake manifold.
3. Remove two bolts (4) connecting EGR tube (1) to
valve assembly.
4. Remove gasket located between EGR tube flange
and EGR valve assembly.
5. Remove two EGR valve mounting bolts (5).
6. Separate valve assembly (3) from engine.
7. Remove and discard metal gasket located between
cylinder head and valve assembly.

5.7L
The electronic EGR valve and solenoid assembly (3)
is attached to the front of the right cylinder head (1).
An exhaust gas routing tube connects the EGR valve
to the intake manifold.
1. Disconnect electrical connector (1) from EGR sole-
noid (2).
2. Remove two bolts (3) connecting EGR tube (4) to
valve assembly.
3. Remove gasket located between EGR tube flange
and EGR valve assembly.

4. Remove two mounting bolts (2).
5. Separate valve assembly (3) from cylinder head
(1).
6. Remove and discard metal gasket located between
cylinder head and valve assembly.
INSTALLATION
4.7L
1. Clean area at rear of left cylinder head where it
joins base of EGR valve.
2. Clean EGR tube where it joins EGR valve.
3. Position new gasket between EGR valve and cylin-
der head.
4. Position EGR valve to cylinder head. Install and
tighten two bolts (5) to 20 ft.lbs. (27 Nꞏm).
5. Position new gasket between EGR tube flange and
EGR valve assembly.
6. Position EGR tube (1) to side of EGR valve and
into intake manifold. Install two bolts (4) finger tight
(temporarily).

7. Install EGR tube flange bolt (1) at intake manifold.
Tighten bolt to 20 ft.lbs. (27 Nꞏm).
8. Connect electrical connector (5) to top of EGR
valve solenoid (2).
9. Do a final tightening of two EGR tube bolts (4) to
20 ft.lbs. (27 Nꞏm).

5.7L
1. Position a new metal gasket between cylinder head
(1) and valve assembly (3).
2. Install two mounting bolts (2) and tighten to 20
ft.lbs. (27 Nꞏm).
3. Clean EGR tube where it joins EGR valve.
4. Position new gasket between EGR tube flange and
EGR valve assembly.
5. Install two bolts (3) connecting EGR tube (4) to
valve assembly (2) and tighten to 20 ft.lbs. (27
Nꞏm).
6. Connect electrical connector (1) to EGR solenoid
(2).
