This procedure covers the replacement of an exhaust clamp on a 2018-2024 Toyota Camry with the 2.5L I4 engine, typically used to seal joints between exhaust pipes or repair minor exhaust leaks.

Warnings

Tools required

Parts

• Exhaust clamp × 1 — Size and type specific to location (band clamp or saddle clamp)
• Exhaust gasket (if applicable) × 1 — Use OEM specification for flange connections

Preparation

1. Ensure engine and exhaust system are completely cold to the touch
2. Park vehicle on level ground and engage parking brake
3. Place wheel chocks behind rear wheels
4. Raise front of vehicle with floor jack and support securely on jack stands at manufacturer-approved lift points
5. Visually inspect exhaust system to locate the clamp requiring replacement and identify clamp type (band clamp or saddle clamp)

Procedure

1. 1

   Access the exhaust clamp
   From underneath the vehicle, locate the exhaust clamp to be replaced. If necessary, remove any heat shields blocking access using a 10mm socket. Store heat shield bolts for reinstallation.
   Torque spec

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

   Apply penetrating oil
   Spray penetrating oil on the clamp bolts and allow to soak for 5-10 minutes if clamp shows signs of corrosion. This will ease removal and prevent bolt breakage.
3. 3

   Loosen and remove old clamp
   Using the appropriate socket (typically 12mm or 14mm depending on clamp type), loosen the clamp bolt(s). For band clamps, there will be one bolt. For saddle clamps, there will be two bolts. Remove the old clamp completely and inspect the exhaust pipe joint for damage or excessive corrosion.
4. 4

   Clean pipe surfaces
   Use a wire brush to clean any rust, carbon deposits, or old gasket material from both pipe surfaces where the clamp will seal. Ensure surfaces are smooth and free of debris for proper sealing. If this is a flanged connection, remove the old gasket completely.
5. 5

   Position new clamp
   If replacing a clamp at a flanged connection, install a new exhaust gasket between the flanges. Position the new exhaust clamp around the pipe joint, ensuring it is centered over the connection point. For slip-fit joints, ensure pipes are fully inserted and aligned before positioning clamp.
6. 6

   Install and tighten clamp
   Install the clamp bolt(s) and tighten by hand until snug. If this is a flanged connection with bolts passing through the flanges, apply anti-seize to bolt threads and torque to specification. For standard band or saddle clamps on slip-fit joints, tighten clamp bolt evenly to manufacturer specification (typically 35-45 Nm for this vehicle). Ensure clamp is seated properly and pipe alignment has not shifted.
   Torque spec

   Exhaust Flange Bolts45 Nm (33 lb-ft)
7. 7

   Reinstall heat shields
   If heat shields were removed, reinstall them in their original positions and torque bolts to specification. Ensure heat shields are not contacting exhaust pipes directly and have proper clearance.
   Torque spec

   Heat Shield Bolts10 Nm (7 lb-ft)

Reassembly

1. Verify all exhaust hangers are properly seated in their rubber mounts
2. Check that no exhaust components are contacting the chassis, suspension, or body panels
3. Ensure all heat shields are securely fastened and properly positioned

Verification

• Lower vehicle from jack stands carefully
• Start engine and listen for exhaust leaks at the clamp location. A hissing or ticking sound indicates an improper seal
• With engine at idle, carefully feel around the clamp area (without touching hot components) for escaping exhaust gases
• Rev engine to 2000-3000 RPM and verify no leaks are present under load
• Take vehicle for a short test drive and recheck clamp area for leaks after exhaust system reaches operating temperature
• After first drive cycle, allow exhaust to cool and verify clamp bolts have not loosened. Re-torque if necessary
