Exhaust Manifold Replacement Right
Removal Procedure
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Disconnect the exhaust pipe from the exhaust manifold. Refer to
Catalytic Converter Replacement
in Engine Exhaust.
- Lower the vehicle.
- Remove the air cleaner outlet duct from the throttle body and
the air cleaner assembly. Refer to
Air Cleaner Outlet Duct Replacement
in Engine Controls.
- Remove the secondary air injection (AIR) pipe assembly, if equipped
from the exhaust manifold. Refer to
Secondary Air Injection Check Valve and Check Valve Pipe Replacement - Bank 2
in Engine Controls.
- Disconnect the spark plug wires from the spark plugs. Refer to
Spark Plug Wire Harness Replacement
in Engine Electrical.
- Remove the exhaust manifold
bolts.
- Remove the exhaust manifold and the spark plug wire shields from
the engine.
- Clean all gasket surfaces. Refer to
Exhaust Manifold Cleaning and Inspection
.
- Remove the heat shield from the exhaust manifold, if necessary.
Installation Procedure
- Install the heat shield
to the exhaust manifold, if removed.
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.
- Install the heat
shield bolts.
Tighten
Tighten the heat shield bolts to 9 N·m (80 lb in).
Important: To assist in installing the exhaust manifold to the engine, the tabs
at the bolt holes on a NEW exhaust manifold gasket will hold the bolts and
gaskets in place.
- Sub-assemble the bolts, spark plug wire shields, and NEW gaskets to
the exhaust manifold.
- Install the exhaust manifold. Refer to Exhaust Manifold Installation (Right)
.
- Install the AIR pipe assembly, if equipped to the exhaust manifold.
Refer to
Secondary Air Injection Check Valve and Check Valve Pipe Replacement - Bank 2
in Engine Controls.
- Connect the spark plug wires to the spark plugs. Refer to
Spark Plug Wire Harness Replacement
in Engine Electrical.
- Install the air cleaner outlet duct to the throttle body and the
air cleaner assembly. Refer to
Air Cleaner Outlet Duct Replacement
in Engine Controls.
- Raise the vehicle.
- Connect the exhaust pipe to the exhaust manifold. Refer to
Catalytic Converter Replacement
in Engine Exhaust.
- Lower the vehicle.
