Exhaust Seal Replacement Exhaust Manifold Pipe Seal

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



2. Remove the right (rear) exhaust manifold pipe nuts from the exhaust manifold studs.

Important: Suitably support the exhaust system where hangers are removed.

3. In order to remove the exhaust manifold pipe seal disconnect any hangers necessary to reposition the exhaust system.
4. Reposition the exhaust system.
5. Remove the exhaust manifold pipe seal.
6. Inspect all of the components for the following:

•

Cracks

•

Bends

•	Stripped threads

•	Corrosion damage

•

Leaks

•	Replace the components as necessary.

1. Install the exhaust manifold pipe seal.
2. Return the exhaust system to the proper position.
3. Connect any hangers.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the right (rear) exhaust manifold pipe nuts to the exhaust manifold pipe studs.

Tighten
Tighten the right (rear) exhaust manifold pipe nuts to 30 N·m (22 lb ft)

5. Remove the exhaust system support.
6. Lower the vehicle.
7. Inspect the exhaust system for leaks and underbody contact.

2. Support the exhaust pipe and the exhaust resonator pipe.

Important: Suitably support the exhaust system where hangers are removed.

3. In order to remove the exhaust resonator gasket disconnect any hangers necessary to reposition the exhaust system.
4. Remove the exhaust resonator bolts from the exhaust resonator pipe flange.
5. Reposition the exhaust system.
6. Remove the exhaust resonator gasket.
7. Inspect all of the components for the following damage. Replace the components as necessary:

•

Cracks

•

Bends

•	Stripped threads
