EGR Tube

Replacement of the EGR tube that connects the EGR valve to the exhaust manifold, restoring proper exhaust gas recirculation function.

Warnings

Tools required

Parts

• EGR tube assembly × 1 — Use OEM specification
• EGR tube to manifold gasket × 1 — Use OEM specification
• EGR tube to valve gasket × 1 — Use OEM specification

Preparation

1. Ensure engine is completely cool to the touch
2. Disconnect negative battery terminal
3. Apply penetrating oil to all EGR tube fasteners and allow to soak for at least 30 minutes
4. Remove engine cover if equipped by pulling upward on perimeter clips
5. Place vehicle on level ground with parking brake engaged

Procedure

1. 1

   Remove heat shield
   Locate the heat shield covering the EGR tube and exhaust manifold area. Remove the heat shield mounting bolts using a 10mm socket. There are typically 2-3 bolts securing the shield. Carefully remove the heat shield and set aside.
   Torque spec

   Heat Shield Bolts10 Nm (7 lb-ft)
2. 2

   Disconnect electrical connector
   Locate the EGR valve mounted on the intake manifold. Press the locking tab and disconnect the electrical connector from the EGR valve. Move the wiring harness aside to provide working clearance.
3. 3

   Remove EGR valve mounting bolts
   Using a 12mm socket, remove the two mounting bolts securing the EGR valve to the intake manifold. Support the EGR valve and tube assembly while removing the bolts to prevent stress on the tube.
   Torque spec

   Mounting Bolts26 Nm (19 lb-ft)
4. 4

   Remove EGR tube exhaust manifold flange
   Locate where the EGR tube connects to the exhaust manifold via a flanged connection. Using a 14mm socket, remove the two flange bolts. Work carefully as these bolts are exposed to high heat and may be corroded. If resistance is encountered, apply additional penetrating oil and allow to soak.
   ⚠Do not force corroded fasteners. If bolts will not turn, apply heat using a propane torch to break corrosion bond.
   Torque spec

   Exhaust Flange Bolts45 Nm (33 lb-ft)
5. 5

   Remove EGR tube assembly
   With both connections loosened, carefully maneuver the EGR tube assembly out of the engine bay. The tube may be routed behind or around other components, so take note of the routing path for reinstallation. Remove and discard the old gaskets from both the EGR valve mounting surface and exhaust manifold flange.
6. 6

   Clean mounting surfaces
   Using a wire brush or gasket scraper, thoroughly clean all gasket surfaces on the intake manifold EGR valve mounting point and the exhaust manifold flange. Remove all carbon deposits, old gasket material, and corrosion. Wipe clean with shop towels. Inspect exhaust manifold studs for damage or excessive corrosion.
7. 7

   Prepare new EGR tube
   Inspect the new EGR tube for shipping damage. Install new gaskets onto the tube assembly - one at the EGR valve end and one at the exhaust manifold flange. Apply a thin coat of anti-seize compound to the threads of the exhaust flange bolts only.
8. 8

   Install EGR tube assembly
   Route the new EGR tube into position following the same path as the original. Align the tube flange with the exhaust manifold connection first, then position the EGR valve end to the intake manifold. Start all fasteners by hand before tightening any to ensure proper alignment.
9. 9

   Torque exhaust manifold flange
   Using a torque wrench and 14mm socket, tighten the exhaust flange bolts in an alternating pattern to 45.0 Nm (33.0 lb-ft). This ensures even gasket compression and proper sealing.
   Torque spec

   Exhaust Flange Bolts45 Nm (33 lb-ft)
10. 10

    Torque EGR valve mounting bolts
    Using a torque wrench and 12mm socket, tighten the EGR valve mounting bolts to the intake manifold to 26.0 Nm (19.0 lb-ft). Tighten in an alternating pattern to ensure even seating.

    Mounting Bolts26 Nm (19 lb-ft)
11. 11

    Reconnect electrical and reinstall heat shield
    Reconnect the electrical connector to the EGR valve, ensuring it clicks into place. Position the heat shield over the EGR tube and exhaust manifold area. Install and torque the heat shield bolts to 10.0 Nm (7.0 lb-ft) using a 10mm socket.
    Torque spec

    Heat Shield Bolts10 Nm (7 lb-ft)
12. 12

    Reinstall engine cover and battery
    If equipped, reinstall the engine cover by aligning the clips and pressing firmly until seated. Reconnect the negative battery terminal. Clear any stored EGR-related diagnostic trouble codes using an OBD-II scanner if available.

Reassembly

1. Ensure all electrical connections are secure and properly seated
2. Verify heat shield is properly positioned and all bolts are tight
3. Double-check that no tools or materials were left in the engine bay

Verification

• Start the engine and allow it to reach operating temperature while monitoring for exhaust leaks at the EGR tube connections
• Listen for any hissing or ticking sounds that would indicate an exhaust leak
• Check for diagnostic trouble codes related to EGR system function
• Perform a visual inspection of all connections while engine is running to confirm no exhaust gases are escaping
• Test drive the vehicle and verify smooth operation with no EGR-related fault codes
