Steps

This procedure covers the removal and replacement of the EGR (Exhaust Gas Recirculation) valve on a 2014 Ram 2500 equipped with the 6.7L Cummins Diesel engine.

Warnings

⚠️Allow engine to cool completely before beginning work. EGR components operate at extremely high temperatures and can cause severe burns.

⚠The EGR valve and connecting tubes may contain carbon deposits. Avoid breathing carbon dust and work in a well-ventilated area.

⚠Do not drop fasteners or debris into the intake manifold or exhaust system openings.

Parts

EGR Valve Assembly × 1 — Use OEM specification
EGR Valve Gasket × 1 — Use OEM specification
EGR Tube Gasket × 1 — Use OEM specification

Preparation

Ensure engine is completely cool to the touch
Disconnect negative battery cable
Remove engine cover by pulling upward on mounting grommets
Spray all EGR valve and tube fasteners with penetrating oil and allow to soak for 10-15 minutes

Procedure

1
Disconnect electrical connector
Locate the EGR valve on the driver's side of the engine near the intake manifold. Press the tab on the electrical connector and pull straight away from the EGR valve to disconnect. Move the wiring harness aside.
2
Remove EGR tube fitting
Locate the EGR tube connecting the EGR valve to the exhaust manifold. Remove the tube fitting at the EGR valve end by loosening the retaining nut. Note the position and orientation of any sealing washers or gaskets.
Torque spec
EGR Tube Fitting35 Nm (26 lb-ft)
3
Remove EGR valve mounting bolts
Remove the three bolts securing the EGR valve to the intake manifold. Support the EGR valve while removing the final bolt to prevent it from falling. Carefully pull the EGR valve away from the mounting surface.
Torque spec
EGR Valve Bolts25 Nm (18 lb-ft)
4
Remove and inspect old gasket
Remove the old EGR valve gasket from the mounting surface on the intake manifold. Use a gasket scraper to carefully clean the mounting surface, ensuring all old gasket material and carbon deposits are removed. Do not allow debris to fall into the intake manifold opening.
⚠Cover the intake manifold opening with a clean shop rag to prevent debris entry while cleaning the mounting surface.
5
Inspect EGR passages
Inspect the EGR passage in the intake manifold for excessive carbon buildup. If heavy buildup is present, use a wire brush to clean the passage opening. Wipe clean with a shop rag and ensure no debris remains in the intake tract.
6
Prepare new EGR valve
Remove the new EGR valve from packaging and verify it matches the original. Install the new EGR valve gasket onto the mounting surface of the intake manifold, ensuring proper alignment with bolt holes and passages.
7
Install new EGR valve
Position the new EGR valve onto the mounting gasket, aligning all bolt holes. Thread all three mounting bolts by hand to ensure proper thread engagement. Tighten the bolts in a crisscross pattern to the specified torque.

EGR Valve Bolts25 Nm (18 lb-ft)
8
Reconnect EGR tube
Install a new EGR tube gasket if provided. Position the EGR tube to the EGR valve and hand-thread the retaining nut. Ensure the tube is properly seated before tightening to the specified torque.
Torque spec
EGR Tube Fitting35 Nm (26 lb-ft)
9
Reconnect electrical connector
Push the electrical connector onto the EGR valve until it clicks into place. Gently tug on the connector to verify it is fully seated and locked.
10
Reinstall engine cover and battery
Reinstall the engine cover by pressing down firmly on all mounting points until grommets are fully seated. Reconnect the negative battery cable.

Reassembly

Ensure all electrical connections are secure and locked in place
Verify all fasteners are tightened to proper torque specifications
Confirm no tools or parts are left in the engine compartment

Verification

Start the engine and allow it to idle. Listen for any exhaust leaks at the EGR valve or tube connections
Check for proper EGR valve operation by allowing the engine to reach operating temperature and verify no check engine light illuminates
Use a scan tool to monitor EGR system performance and verify no diagnostic trouble codes are present
Perform a visual inspection for any coolant, oil, or exhaust leaks around the EGR valve after test drive
