Dodge Journey: Tube, exhaust gas recirculation (EGR)

Removal

2.7L - LOWER TUBE

Emissions Control
Fig. 50: Lower Exhaust Gas Recirculation Tube - 2.7L

WARNING: The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled.

1. Remove lower EGR tube nut (3) from exhaust manifold.

2. Remove lower EGR tube bolts (1) from EGR valve (5).

3. Remove gasket (4) from EGR valve (5). Clean gasket surfaces on EGR valve.

4. Remove lower EGR tube (2) from vehicle.

2.7L - UPPER TUBE

Emissions Control
Fig. 51: Upper Tube

WARNING: The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled.

1. Disconnect negative battery cable.

2. Remove upper bolts (1) from intake manifold. Inspect gasket, replace if necessary.

3. Remove bolts (5) attaching upper tube (2) to EGR valve (3).

4. Remove the gasket (4) between upper tube (2) and EGR valve (3).

CAUTION: Clean mounting surface of EGR valve. Do not use sharp metal scraping tools. Damage may occur to the sealing surfaces of the EGR valve causing a leak.

5. Clean mounting surface of EGR valve.

3.5L

Emissions Control
Fig. 52: UPPER MOUNTING

WARNING: The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled.

1. Remove two upper tube mounting bolts.

2. When removing EGR tube assembly be careful not to drop the silicone rubber seals into the intake manifold. Clean gasket surfaces on the EGR valve. Note that any loose dirt can lodge between the pintle and the seat and cause valve leakage that will give a rough idle and depressed manifold vacuum.

3. Remove two lower tube mounting bolts.

4. Remove tube assembly from vehicle.

Installation

2.7L - LOWER TUBE

Emissions Control
Fig. 54: Lower Exhaust Gas Recirculation Tube - 2.7L

1. Install gasket (4) to EGR valve (5).

2. Install lower EGR tube (2) to vehicle.

3. Install lower EGR tube bolts (1) to EGR valve (5). Tighten bolts to 12 N.m (106 in. lbs.).

4. Install lower EGR tube nut (3) to exhaust manifold. Tighten nut to 70 N.m (51.5 ft. lbs.).

2.7L - UPPER TUBE

Fig. 55: Identifying Inner Exhaust Gas Recirculation Tube Seal

CAUTION: Do Not use metal scrapers when cleaning the mounting surface of the EGR valve. Damage from scratching the surface may cause an improper seal.

CAUTION: Do not allow debris to enter the EGR valve when cleaning the mounting surface. Debris can lodge between the pintle and the seat causing valve leakage that results in rough idle and depressed manifold vacuum.

1. Clean and inspect gasket sealing surfaces.

NOTE: Install new rubber silicone seals on intake manifold end of EGR tube any time it is removed from the intake manifold.

2. Install new silicone rubber seal (1) on the intake manifold end of the EGR tube. Position seal 17 mm (0.67 in.) from the tube flange.

3. Lubricate the EGR mounting tube hole in the intake manifold with Mopar Rubber Bushing Installation Lube. Do not lubricate the EGR tube or seal.

4. Install the EGR tube (3) into the intake manifold (2) being careful not to damage the silicone rubber seals, and verify that the seals are correctly positioned in the intake manifold.

5. Install new gasket (4) between the EGR valve (3) and tube (2) and install bolts (5). Tighten bolts to 12 N.m (106 in. lbs.).

  2. - intake manifold

NOTE: The EGR tube flange (1) does not need to be flush with the intake manifold (2) to be sealed. The EGR tube flange can be up to 2 mm (0.08 in.) from intake manifold and still be sealed. This design allows the EGR tube position to vary with the tolerance stack up and remain properly sealed.

6. Tighten the EGR tube to intake manifold bolts (1) to 6 N.m (53 in. lbs.).

7. Connect negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
