Exhaust Manifold Replacement Left

1. Disconnect the negative battery cable. Refer to

   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.

   in General Information.



2. Remove the accessory drive belt from the power steering and generator pulleys. 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 SECTION 0A.
5. Remove the splash shield from the right wheel well.
6. Remove the lower center air deflector.
7. Remove the generator rear bracket.
8. Remove the lower retaining bolt from the generator.
9. Set the generator aside.



10. Remove the left exhaust manifold (5) to exhaust crossover pipe (4) bolts.
11. Remove the electrical connectors at the oxygen sensors.
12. Remove the power steering line retainers.



13. Remove the left exhaust manifold nuts.
14. Remove the left exhaust manifold.
15. Remove the left exhaust manifold gasket. Discard the gasket if damaged.
16. Remove the oxygen sensor from the manifold.

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

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

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 gasket to the manifold. Hold the gasket in position by installing 2 nuts.
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 24 N·m (18 lb ft).

6. Install the electrical connector to the oxygen sensors.
7. Install the power steering line retainers.
8. Install the lower retaining bolt to the generator. Refer to Generator Replacement in Engine Electrical.

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

9. Install the generator rear bracket.
10. 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).

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

Tighten
Tighten the flange bolts to 50 N·m (37 lb ft).

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

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




16. Install the accessory drive belt onto the power steering and generator pulleys.
