1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



2. Remove the AIR shield mounting bolts.



3. Remove the AIR shield.



4. Remove the spring clamps (4).
5. Remove the air injection reactor pump hoses (3) from the pump assembly (1).
6. Disconnect the AIR pump and solenoid electrical connectors.
7. Disconnect the vacuum hose (2) from the solenoid (5).
8. Remove the AIR pump mounting bolts (6).
9. Remove the AIR pump assembly (1).

1. Align the AIR pump bracket with the mounting holes.

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.
