Replace or install an exhaust clamp on the 2014 Ram 2500 with 6.7L Cummins Diesel engine to repair exhaust leaks or secure exhaust components.

Warnings

Tools required

Parts

• Exhaust clamp (band clamp or lap joint clamp as applicable) × 1 — Use OEM specification or equivalent
• Exhaust gasket (if replacing at flange connection) × 1 — Use OEM specification

Preparation

1. Ensure engine and exhaust system are completely cold to the touch
2. Park vehicle on level surface, engage parking brake, and chock rear wheels
3. Raise front of vehicle with floor jack and support securely on jack stands rated for vehicle weight (approximate 7,000+ lbs)
4. Inspect exhaust system to locate damaged or leaking clamp and identify clamp type (band clamp, lap joint clamp, or flange connection)
5. Apply penetrating oil to clamp fasteners and allow to soak for 10-15 minutes if corroded

Procedure

1. 1

   Access the exhaust clamp location
   Position yourself under the vehicle with adequate lighting. Locate the exhaust clamp requiring replacement. On the 6.7L Cummins, common clamp locations include the turbo downpipe connection, mid-pipe joints, and connections before the diesel particulate filter (DPF). Verify there is adequate clearance to work and identify any heat shields that may need temporary removal for access.
2. 2

   Remove heat shield if necessary
   If a heat shield blocks access to the clamp, remove the heat shield mounting bolts. Note the orientation and position of the heat shield for reinstallation. Set hardware aside in a container to prevent loss.

3. 3

   Loosen and remove old clamp
   For band clamps: Loosen the clamp bolt(s) completely but do not remove. Tap the clamp gently with a socket extension to break it free from corrosion, then slide off the pipe. For lap joint clamps: Remove both nuts/bolts and separate the clamp halves. For flange connections secured by clamps: Remove clamp hardware and separate the flange. Inspect the pipe ends for damage, excessive rust, or deformation that could prevent proper sealing.
4. 4

   Clean mating surfaces
   Use a wire brush to thoroughly clean both pipe ends where the clamp will seal. Remove all rust, carbon deposits, and old gasket material if applicable. For flange connections, ensure both flange faces are clean and flat. Wipe surfaces with a clean rag to remove debris. Inspect pipes for cracks or holes that would require pipe replacement rather than just clamp replacement.
5. 5

   Position new clamp and align pipes
   For slip-joint connections, slide the new clamp over the rear pipe section first, pushing it well back from the joint. Insert the front pipe into the rear pipe, ensuring proper overlap (typically 2-3 inches minimum). Align pipes so they are concentric and properly oriented with no binding against chassis or other components. For flange connections, install new gasket if applicable and align bolt holes. Apply anti-seize compound to bolt threads per torque specifications.
6. 6

   Install and torque clamp fasteners
   Slide the clamp into position over the joint, centering it on the connection. For band clamps, position the clamp bolt access for future service. Start all fasteners hand-tight. For flange connections with clamps, ensure the clamp bridges both flanges evenly. Torque fasteners gradually in a cross-pattern if multiple bolts exist, bringing the joint together evenly. For exhaust flange bolts, apply anti-seize and torque to specification. For standard band clamps, tighten the clamp bolt until the gap closes to approximately 1/8 inch, ensuring firm contact without over-compressing.

   Check clearances and reinstall heat shield
   Verify the exhaust pipe has adequate clearance from the chassis, fuel lines, brake lines, and driveshaft through full suspension travel. Gently push up and down on the pipe to simulate movement. If heat shield was removed, reinstall it in the original position and torque mounting bolts to specification. Ensure heat shield does not contact or rattle against exhaust pipes.

8. 8

   Lower vehicle and perform initial inspection
   Carefully lower the vehicle from jack stands and remove support equipment. Perform a visual inspection of the repair area from above and below the vehicle. Ensure all tools and parts have been removed from under the vehicle.

Reassembly

1. Ensure all heat shields are properly reinstalled and secured
2. Verify exhaust hangers are properly seated and supporting the system weight
3. Double-check that all clamp fasteners are tight and the joint is properly sealed

Verification

• Start the engine and allow it to idle. Listen carefully for any exhaust leaks at the clamp location
• With engine running, carefully feel around the clamp area (without touching hot components) for escaping exhaust gases
• Perform a visual inspection while engine is running to look for visible exhaust smoke or soot escaping from the joint
• Rev engine slightly (1500-2000 RPM) to increase exhaust pressure and verify seal holds under load
• After a short test drive, re-inspect the clamp area for any signs of leakage or loosening
• Check that no exhaust odors are entering the cabin during operation
