1. Open the hood.

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

2. Disconnect the battery negative cable from the battery. Refer to Battery Cable in Engine Electrical.
3. Remove the oil level indicator and tube from the engine block. Refer to Oil Level Indicator and Tube Replacement.



4. Remove the EGR valve pipe from the left exhaust manifold.
5. Remove the spark plugs cylinder head. Refer to Spark Plug Replacement in Engine Electrical.
6. Raise the vehicle and support the vehicle with safety stands. Refer to Lifting and Jacking the Vehicle in General Information.
7. Remove the exhaust pipe from the exhaust manifold. Refer to Catalytic Converter Replacement.
8. Lower the vehicle.



9. Remove the exhaust manifold retaining nuts.
10. Remove the exhaust manifolds from the cylinder head.
11. Remove the exhaust manifold gasket from the cylinder head.
12. Clean and check the gasket mating surface and the cylinder head. Refer to Cylinder Head Clean and Inspect .

Important: Install the exhaust manifold gasket with the stamped 7.4 facing away from the cylinder head.

1. Install the exhaust manifold gasket to the cylinder head.



2. 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.

3. Install the exhaust manifold retaining bolts and nuts.

5. Install the oil level indicator tube to the exhaust manifold. Refer to Oil Level Indicator and Tube Replacement.
6. Install the spark plugs to the cylinder head. Refer to Spark Plug Replacement in Engine Electrical.
7. Raise the vehicle and support with safety stands. Refer to Lifting and Jacking the Vehicle in General Information.
8. Install the exhaust pipes to the exhaust manifolds. Refer to Catalytic Converter Replacement.
9. Lower the vehicle.



10. Install the EGR pipe to the intake manifold and the exhaust manifold.

Tighten
