Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System
Operation
This system reduces the amount of oxides of nitrogen (NO
x
) in the exhaust by allowing a predetermined amount of exhaust gases to
recirculate and dilute the incoming fuel/air mixture. The diluted
air/fuel mixture reduces peak flame temperature during combustion,
which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses

Removal & Installation
EGR Tube
EGR tube used on the 3.5L engine
Be sure to have the insulation snug against the back of the wiring harness when installing the EGR tube-3.5L engine
The EGR tube attaches to both sides of the intake manifold plenum and the EGR valve.
Remove the air cleaner plenum from the rear of the engine.
Remove the EGR tube and valve screws.
Remove the tube-to-intake plenum screws.
Remove the EGR tube. Discard the old gaskets.
Clean the gaskets surfaces.
To install:
Loosely install the EGR tube to the EGR valve screws. Finger-tighten the EGR tube mounting screws.
Tighten the EGR tube to the EGR valve screws to 95 inch lbs. (11 Nm).
Tighten the EGR tube to the intake manifold plenum screws to 16 ft. lbs. (22 Nm).
Ensure that the insulation on the EGR tube aligns with and
contacts the insulation on the vacuum harness at the rear of the engine.
I hope help you with this; remember rated this help. Good luck.
