12. Remove the MAP sensor bracket and bolts.
13. Remove the boost control solenoid. Refer to Boost Control Solenoid Replacement in Engine Controls - 3.8L.
14. Remove the air cleaner intake duct. Refer to Air Cleaner Inlet Duct Replacement in Engine Controls - 3.8L.



15. Remove the nuts securing the throttle body to the supercharger.
16. Remove the throttle body and position aside.
17. Remove the throttle body gasket.



18. Remove the supercharger mounting bolts.
19. Remove the supercharger from the intake manifold.
20. Clean and inspect the supercharger. Refer to Supercharger Cleaning and Inspection .
21. Clean the lower intake manifold mating surface.

Important: Do not use any sealer on the gasket.

1. Install the new supercharger gasket.



2. Position the supercharger to the intake manifold.

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.
