Exhaust Manifold Replacement Left

1. Remove the two bolts attaching the left exhaust manifold to the crossover pipe.
2. Disconnect the spark plug wires from the spark plugs.
3. Remove the oil level indicator and the tube. Refer to Oil Level Indicator and Tube Replacement .
4. Remove lift bracket and retaining bolts.



5. Remove the exhaust manifold studs and bolts.
6. Remove the exhaust manifold.

1. Install the exhaust manifold to the cylinder head.

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.

2. Install the exhaust manifold studs and bolts.

Tighten
Tighten the studs and bolts to 30 N·m (22 lb ft).

3. Install the oil level indicator and the tube. Refer to Oil Level Indicator and Tube Replacement .
4. Reconnect the spark plug wires.



5. Install the two bolts attaching the left exhaust manifold to the exhaust crossover pipe.

Tighten
Tighten the bolts to 18 N·m (13 lb ft).

6. Install lift bracket.

Exhaust Manifold Replacement Right

Important: Inspect the EGR outlet pipe for leaks, whenever the pipe is removed from the right hand exhaust manifold. If a leak exists, replace the EGR adapter.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical
2. Disconnect the spark plug wires from the spark plugs.
3. Remove the transmission oil level indicator and the indicator tube. Refer to Transmission Fluid Filler Tube Replacement in Transmission.
4. Remove the oxygen sensor electrical connector.
5. Remove the two bolts attaching the right exhaust manifold to the crossover pipe.
6. Raise the vehicle. Suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
7. Remove the front exhaust pipe from the exhaust manifold. Refer to Front Pipe Replacement in Engine Exhaust.
8. Lower the vehicle.



9. Remove the engine lift bracket.
