EGR Tube

This procedure covers removal and replacement of the EGR tube on a 2011-2014 Ford F-150 with the 5.0L Coyote V8 engine, including exhaust flange disconnection and EGR valve interface.

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. Park vehicle on level ground and engage parking brake
2. Ensure engine is completely cold (minimum 2 hours after last operation)
3. Disconnect negative battery cable to prevent accidental short circuits
4. Raise hood and secure with prop rod
5. Remove engine cover by pulling upward on retaining clips
6. If severely corroded, spray all EGR tube fasteners with penetrating oil and wait 30 minutes

Procedure

1. 1

   Access EGR valve area
   Locate the EGR valve on the passenger side of the engine near the firewall. Remove any air intake components obstructing access to the EGR valve. On some configurations, you may need to disconnect the air intake tube at the throttle body to improve working clearance.
2. 2

   Disconnect EGR valve electrical connector
   Press the locking tab on the EGR valve electrical connector and pull straight away from the valve. Position the wiring harness out of the work area to prevent damage.
3. 3

   Remove EGR valve mounting bolts
   Using a 10mm socket, remove the two bolts securing the EGR valve to the intake manifold. Note the bracket orientation if present. The valve will remain attached to the EGR tube at this stage.
   ⚠Do not pry on the EGR valve body as the internal components are fragile and easily damaged.
4. 4

   Locate exhaust manifold connection point
   Trace the EGR tube from the valve down to the passenger-side exhaust manifold. The tube connects to the manifold with a flanged connection. On 4WD models, access may require reaching over or around the front differential housing.
5. 5

   Remove exhaust flange bolts
   Using a 13mm socket with extension, remove the two bolts securing the EGR tube flange to the exhaust manifold. These bolts are prone to seizing due to heat exposure. If resistance is encountered, reapply penetrating oil and wait before proceeding. A universal joint may be required due to limited access angles.
   ⚠Excessive force on seized bolts can result in broken studs requiring exhaust manifold removal for repair. Work slowly and use heat if necessary.

   Exhaust Flange Bolts45 Nm (33 lb-ft)
6. 6

   Remove EGR tube assembly
   Carefully maneuver the EGR tube assembly away from the engine, separating it from both the EGR valve and exhaust manifold connection points. The tube may be routed around or near engine wiring and coolant hoses—take care not to damage adjacent components during removal. Note the routing path for installation reference.
7. 7

   Clean mating surfaces
   Using a wire brush, thoroughly clean the EGR valve mounting surface on the intake manifold and the exhaust manifold flange where the EGR tube connects. Remove all carbon deposits and old gasket material. Inspect both surfaces for cracks or warping. Clean the EGR valve mounting flange if reusing the valve.
8. 8

   Inspect and prepare new EGR tube
   Verify the new EGR tube matches the original routing and has the correct flange orientations for 4WD configuration. Install new gaskets on both the EGR valve end and the exhaust manifold flange end. Apply a thin coat of anti-seize compound to the exhaust flange bolt threads.
9. 9

   Position new EGR tube
   Route the new EGR tube assembly into position, aligning the exhaust manifold flange first. Ensure the tube follows the original path and does not contact or put strain on wiring harnesses, coolant hoses, or other components. The tube should sit naturally without forcing.
10. 10

    Install exhaust flange bolts
    Start both exhaust flange bolts by hand to ensure proper thread engagement. Once both bolts are hand-tight, torque them in an alternating pattern to specification using a torque wrench. This ensures even gasket compression and proper sealing.
    ℹ️Anti-seize must be applied to exhaust flange bolt threads to prevent future seizure due to high-temperature exposure.

11. 11

    Connect EGR valve to tube
    Position the EGR valve onto the EGR tube flange with a new gasket in place. Align the valve mounting holes with the intake manifold mounting points. Start both mounting bolts by hand.
12. 12

    Secure EGR valve mounting bolts
    Torque the EGR valve mounting bolts to specification in an alternating pattern. Verify the valve is seated flush against the intake manifold and the EGR tube connection is properly aligned without stress or binding.

    Mounting Bolts34 Nm (25 lb-ft)
13. 13

    Reconnect electrical connector
    Push the EGR valve electrical connector onto the valve until the locking tab clicks into place. Gently pull on the connector to verify it is fully seated and locked.
14. 14

    Reinstall air intake components
    Reinstall any air intake components that were removed for access. Ensure all clamps are tight and all connections are secure. Reinstall the engine cover by pressing down on the mounting points until the retaining clips engage.

Reassembly

1. Verify all fasteners are torqued to specification and no tools or parts remain in the engine bay
2. Reconnect negative battery cable
3. Double-check that all electrical connectors are fully seated and locked

Verification

• Start the engine and allow it to idle for 2-3 minutes while monitoring for exhaust leaks at the EGR tube flange connection (listen for hissing or ticking sounds)
• Verify no unusual odors or smoke from the engine bay
• Check for diagnostic trouble codes using an OBD-II scanner—no EGR-related codes should be present
• Perform a brief test drive and confirm smooth engine operation with no hesitation or rough idle
• After test drive, recheck the exhaust flange connection for any signs of exhaust leakage while engine is still warm
