EGR Tube

This procedure covers the removal and replacement of the EGR tube on the 2018-2024 Toyota Camry with the 2.5L I4 engine, including disconnection from the exhaust manifold and EGR valve.

Warnings

Tools required

Parts

• EGR tube assembly × 1 — Toyota OEM 25620-36020 or equivalent
• EGR tube gasket (exhaust manifold side) × 1 — Use OEM specification
• EGR tube gasket (valve side) × 1 — Use OEM specification

Preparation

1. Ensure engine is completely cool to the touch
2. Raise and secure vehicle on jack stands or lift for improved access from below
3. Remove engine cover by pulling upward on four retaining clips
4. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge
5. Spray all EGR tube fasteners with penetrating oil and allow to soak for 15-30 minutes

Procedure

1. 1

   Remove engine cover components for access
   Remove the plastic engine cover by pulling upward firmly on the four mounting points. If present, remove any additional covers or shields blocking access to the EGR system on the driver's side of the engine. Remove air intake tube if it obstructs access to the EGR valve area.
2. 2

   Disconnect electrical connector from EGR valve
   Locate the EGR valve on the intake manifold side (driver's side of engine). Press the locking tab and disconnect the electrical connector from the EGR valve. Move the wiring harness aside to prevent damage during tube removal.
   ⚠Do not pull on wires; grasp the connector body firmly when disconnecting.
3. 3

   Remove EGR tube mounting bolts at valve
   Using a 12mm socket with extension and universal joint, remove the two bolts securing the EGR tube flange to the EGR valve. Access is tight; work slowly to avoid rounding fasteners. Note the position of any brackets or clips attached to these bolts.

   Exhaust Flange Bolts45 Nm (33 lb-ft)
4. 4

   Remove heat shield if equipped
   If a heat shield is present over the EGR tube or exhaust manifold connection point, remove the retaining bolts using a 10mm socket. Set the heat shield aside for reinstallation.

   Heat Shield Bolts10 Nm (7 lb-ft)
5. 5

   Disconnect EGR tube from exhaust manifold
   Working from below the vehicle provides better access. Locate the two bolts securing the EGR tube to the exhaust manifold. Use a 14mm socket with a long extension to remove these bolts. The lower bolt may require a universal joint for clearance around the exhaust manifold.
   ⚠These bolts are subjected to extreme heat cycles and may be corroded. If bolts begin to round, stop and apply additional penetrating oil or heat.

6. 6

   Remove EGR tube assembly
   With both ends disconnected, carefully maneuver the EGR tube out of the engine bay. The tube routes through a tight space between the exhaust manifold and intake manifold. Twist gently while pulling to break any carbon seal, but avoid excessive force that could damage mounting points.
7. 7

   Clean all mating surfaces
   Using a gasket scraper and wire brush, thoroughly clean the EGR valve mounting flange and exhaust manifold flange. Remove all carbon deposits and old gasket material. The surfaces must be completely clean and flat for proper sealing. Inspect both flanges for cracks or damage.
   ⚠Do not use power tools that could gouge the aluminum EGR valve mounting surface. Hand clean only.
8. 8

   Inspect and prepare new EGR tube
   Compare the new EGR tube to the old unit to confirm correct routing and mounting points. Install new gaskets on both ends of the tube. Apply a thin coating of anti-seize compound to all bolt threads (not gasket surfaces).
9. 9

   Install EGR tube to exhaust manifold
   Position the new EGR tube with gasket to the exhaust manifold flange. Start both bolts by hand to ensure proper thread engagement. Tighten bolts in an alternating pattern to specified torque using a torque wrench.

10. 10

    Connect EGR tube to EGR valve
    Guide the upper end of the EGR tube to the EGR valve mounting flange with gasket in place. Install both mounting bolts with anti-seize on threads. Hand-tighten first, then torque in an alternating pattern to specification. Reinstall any brackets or clips that attach to these bolts.

11. 11

    Reinstall heat shield and accessories
    If removed, reinstall the heat shield over the EGR tube exhaust connection. Torque heat shield bolts to specification. Reinstall air intake tube if it was removed for access.

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

    Reconnect electrical and finalize installation
    Reconnect the electrical connector to the EGR valve, ensuring it clicks firmly into place. Reinstall the engine cover by pressing down on all four mounting points until clips engage. Reconnect the negative battery terminal.

Reassembly

1. Ensure all electrical connectors are firmly seated and locked
2. Verify all heat shields and covers are reinstalled
3. Double-check that no tools or parts were left in the engine bay
4. Confirm engine cover is properly seated on all mounting points

Verification

• Start the engine and allow it to idle for 2-3 minutes while listening for exhaust leaks at both EGR tube connections
• Check for any unusual sounds or vibrations from the EGR system
• With engine running, carefully feel around (not touching hot components) both EGR tube connections for exhaust gas escaping
• Use an OBD-II scanner to verify no EGR-related diagnostic codes are present
• Test drive the vehicle and confirm normal operation with no check engine light
• After test drive, perform a final visual inspection of all connections for signs of leakage or soot deposits
