Exhaust Manifold Replacement Left

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.



2. Remove the accessory drive belt from the power steering (1) and generator pulleys (2). Set the belt aside.
3. Remove the upper retaining bolt from the generator. Refer to Generator Replacement in Engine Electrical.
4. Raise the vehicle. Refer to Lifting and Jacking the Vehicle
5. Remove the splash shield from the right wheel well.
6. Remove the lower center air deflector.
7. Remove the generator. Refer to Generator Replacement in Engine Cranking.
8. Set the generator aside.



9. Remove the left exhaust manifold (5) to exhaust crossover pipe (4) bolts.
10. Remove the electrical connector at the oxygen sensor.
11. Remove the power steering line retainers.



12. Remove the left exhaust manifold nuts.
13. Remove the left exhaust manifold.
14. Remove the left exhaust manifold gasket. Discard the gasket.
15. Remove the oxygen sensor from the manifold. Refer to Heated Oxygen Sensor Replacement in Engine Controls.

1. Coat the threads of the oxygen sensor with high temperature anti-seize, P/N 5613695, or equivalent.

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 oxygen sensor. Refer to Heated Oxygen Sensor Replacement in Engine Controls.

Tighten
Tighten the oxygen sensor to 40 N·m (30 lb ft).




3. Install the gasket to the cylinder head.
4. Install the exhaust manifold by inserting the outlet pipe partially into the exhaust crossover pipe. Move the exhaust manifold into position.
5. Install the exhaust manifold nuts.

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

6. Install the electrical connector to the oxygen sensor.
7. Install the power steering line retainers.
8. Install the lower retaining bolt to the generator.

Tighten
Tighten the retaining bolt to 50 N·m (37 lb ft).

9. Install the generator rear bracket bolt and nut.

Tighten

•	Tighten the generator bolt to 47 N·m (35 lb ft).

•	Tighten the generator nut to 38 N·m (28 lb ft).

10. Install the bolts at the manifold outlet flange. New fasteners are recommended for maximum joint integrity.

Tighten
Tighten the flange bolts to 25 N·m (18 lb ft).

11. Install the lower center air deflector.
12. Install the splash shield to the right wheel well.
13. Lower the vehicle.
14. Install the upper retaining bolt to the generator.

Tighten
Tighten the generator bolt to 50 N·m (37 lb ft).




15. Install the drive belt onto the power steering and generator pulleys.
