Caution: In order to avoid being burned, do not service the exhaust system while it is still hot. Service the system when it is cool.

Caution: Always wear protective goggles and gloves when removing exhaust parts as falling rust and sharp edges from worn exhaust components could result in serious personal injury.

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



2. Remove the four nuts securing the catalytic converter to the exhaust manifold pipe.

Notice: Do not over-flex or damage the flex joint when moving the flex joint from the normal mounting position.

3. Position the exhaust system rearward, enough to allow the studs located in the front of the catalytic converter to clear the exhaust manifold pipe.
4. Remove the catalytic converter gasket. Do not reuse the gasket.



5. Remove the two nuts attaching the exhaust manifold pipe to the right exhaust manifold.
6. Remove the exhaust manifold pipe and the gasket. Do not reuse the gasket.

Notice: When inspecting or replacing exhaust system components, make sure there is adequate clearance from all points on the underbody to prevent overheating of the floor pan and possible damage to the passenger compartment insulation and trim materials.

1. Place a NEW exhaust manifold pipe gasket over the right exhaust manifold studs.
2. Position the exhaust manifold pipe to the right exhaust manifold.

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.

3. Install the two nuts attaching the exhaust manifold pipe to the right exhaust manifold.

Tighten
Tighten the exhaust manifold pipe nuts to 40 N·m (30 lb ft).




4. Place a NEW catalytic converter gasket over the catalytic converter studs.

Notice: Do not over-flex or damage the flex joint when moving the flex joint from the normal mounting position.

5. Position the catalytic converter to the exhaust manifold pipe.
6. Install the four nuts in order to secure the catalytic converter to the exhaust manifold pipe.

Tighten
Tighten the catalytic converter nuts to 25 N·m (18 lb ft).

7. Lower the vehicle.
