Air Cleaner Outlet Resonator (4.2L): Installation
WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
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 air cleaner outlet resonator assembly (5) to the engine making sure of the following:
- The crankcase ventilation hose (1) is connected to the valve cover port (2). See Fig 2.
- The air cleaner outlet resonator (5) is properly fit to the throttle body assembly.
- Install the two air cleaner outlet resonator to engine bolts (4). Tighten the resonator to engine bolts to specification. See TORQUE SPECIFICATIONS .
- Connect the fuel pressure regulator vacuum supply to the air cleaner outlet resonator.
- Connect the air cleaner outlet duct to the air cleaner outlet resonator.
- Connect the electrical connector to the Intake Air Temperature (IAT) sensor (1). See Fig 1.
- Properly position the air cleaner outlet duct and air cleaner outlet resonator clamps (2). Tighten the clamps (2) to specification. See TORQUE SPECIFICATIONS .
