Removal Procedure
Caution: Allow the engine to cool before
servicing the secondary air injection AIR system in order to reduce the
chance of severe burns.
1. Remove the clamp from the check valve.
2. Disconnect the AIR hose from the check valve.
3. Remove the check valve from the left side AIR pipe.
4. Remove the left AIR pipe from the exhaust manifold.

Installation Procedure
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.
1.Install the check valve onto the AIR pipe.
Tighten the check valve to the AIR pipe to 23 N·m (17 lb ft).
2.Connect the AIR pipe to the exhaust manifold.
Tighten the AIR pipe to the exhaust manifold to 20 N·m (15 lb ft).
3. Install the AIR hose to the check valve.
4. Install the check valve clamp.
