Replace a damaged or leaking exhaust clamp on the 2016-2024 Hyundai Tucson 2.5L I4 AWD exhaust system to restore proper sealing and eliminate exhaust leaks.

Warnings

Tools required

Parts

• Exhaust clamp (band or bolt-type) × 1 — Use OEM specification or quality aftermarket
• Exhaust gasket (if flanged connection) × 1 — Use OEM specification

Preparation

1. Ensure engine and exhaust system are completely cold to the touch
2. Park vehicle on level, solid ground and apply parking brake
3. Place wheel chocks behind rear wheels
4. Raise front of vehicle with floor jack and support securely on jack stands placed at designated lift points
5. Inspect exhaust system to identify exact clamp location and type (band clamp or flanged connection)
6. Spray penetrating oil on clamp fasteners and allow 10-15 minutes to penetrate if corrosion is visible

Procedure

1. 1

   Access the exhaust clamp
   Position yourself under the vehicle with adequate lighting. Locate the damaged or leaking exhaust clamp. If a heat shield obstructs access, remove the heat shield mounting bolts. Note the orientation of the clamp and exhaust pipe alignment before disassembly.

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

   Remove the old clamp
   For band-type clamps: Loosen the clamp bolt(s) completely and slide the clamp off the joint. For flanged connections: Remove the flange bolts completely. Support the exhaust pipe to prevent it from dropping or shifting during removal. Inspect the exhaust pipes for damage or excessive corrosion at the joint area.
3. 3

   Clean the joint surfaces
   Use a wire brush to thoroughly clean both mating surfaces of the exhaust pipes, removing carbon deposits, rust, and old gasket material. For slip joints, clean the inside of the outer pipe and outside of the inner pipe. Ensure surfaces are smooth and free of debris for proper sealing.
4. 4

   Inspect and prepare components
   Examine both pipe ends for cracks, excessive corrosion, or deformation that could prevent proper sealing. If replacing a flanged connection, verify the new gasket matches the flange profile exactly. For slip joints, ensure the pipes can slide together with minimal resistance but without excessive play.
5. 5

   Install new gasket (if applicable)
   For flanged connections only: Position the new exhaust gasket between the flange surfaces, ensuring proper alignment with bolt holes. The gasket should sit flat without gaps. For slip joints, no gasket is used; proceed to next step.
   ℹ️Do not reuse old exhaust gaskets as they will not seal properly and will cause exhaust leaks.
6. 6

   Align exhaust pipes
   Carefully align the exhaust pipes at the joint. For slip joints, insert the inner pipe into the outer pipe to the proper depth (typically 2-3 inches of overlap). For flanged connections, align the flanges and bolt holes. Have an assistant support the exhaust if needed to maintain alignment during clamp installation.
7. 7

   Install the new clamp
   For band clamps: Position the new clamp over the slip joint, centered on the overlap area. Ensure the clamp bolt is accessible for tightening. For flanged connections: Apply anti-seize compound to the bolt threads, then install flange bolts finger-tight in a cross-pattern to ensure even gasket compression.
   ℹ️Position band clamps with the fastener oriented away from heat-sensitive components and accessible for future service.
8. 8

   Torque fasteners to specification
   For flanged connections: Using a torque wrench, tighten flange bolts in a cross-pattern to the specified torque value to ensure even gasket compression and prevent warping. For band clamps: Tighten the clamp bolt gradually while verifying the pipes remain properly aligned. Most band clamps do not have a specific torque value; tighten firmly until the clamp is secure and the joint does not move.

9. 9

   Reinstall heat shields
   If heat shields were removed for access, reinstall them in their original positions. Install and torque heat shield bolts to specification. Ensure heat shields do not contact the exhaust pipe directly and have proper clearance.
   Torque spec

   Heat Shield Bolts10 Nm (7 lb-ft)
10. 10

    Verify exhaust hanger alignment
    Check that all nearby exhaust hangers are properly seated in their rubber mounts and that the exhaust system hangs with proper clearance from the vehicle underbody, suspension components, and fuel lines. Adjust hanger positions if necessary to prevent contact or vibration.

Reassembly

1. Verify all fasteners are tightened to specification and no tools or parts have been left under the vehicle
2. Double-check that the exhaust system has adequate clearance from fuel lines, brake lines, and drivetrain components throughout its length

Verification

• Lower the vehicle to the ground and remove jack stands
• Start the engine and listen for exhaust leaks at the repaired joint. A proper repair will produce no hissing or ticking sounds from the clamp area
• With the engine running, carefully feel around the repaired joint (without touching hot surfaces) for exhaust gas escaping, which would indicate an improper seal
• Take a short test drive and verify no exhaust noise, vibration, or smell inside the cabin
• After test drive, re-inspect the clamp area for any signs of leakage or loosening
