Removal

With the vehicle in NEUTRAL, position it on a hoist. Refer to Section 100-02 .

Remove the EGR tube. Refer to Section 303-08 .

Remove the catalytic converter. Refer to Section 309-00 .

Rotate the Supercharger (SC) drive belt tensioner clockwise and remove the drive belt from the SC drive pulley.

Remove the 8 pin-type retainers and the upper radiator sight shield.

Install the Engine Lifting Bracket.

NOTE: The heavy duty Engine Support Bar (303-F070) must be used with the draw screws from the light duty Engine Support Bar (303-F072). This will provide enough clearance between the SC and the Engine Support Bar, and enough clearance between the draw screw and the vehicle hood.
Install the Engine Support Bars.
- Remove the RH engine support insulator nut.
- Using the Engine Support Bars, raise the RH side of the engine.

Remove the 3 bolts and lower the underbody shield.

Remove the SC drive belt from the A/C compressor pulley.

Remove the nut and disconnect the wiring harness retainers from the A/C compressor and stud bolts.

NOTE: The A/C compressor stud bolts must be loosened to gain access to the RH exhaust manifold nuts.
Loosen the A/C compressor stud bolts 25 mm (0.98 in).

Remove the 8 nuts and the RH exhaust manifold.
- Discard the nuts and gaskets.

Clean and inspect the RH exhaust manifold. Refer to Section 303-00 .

Remove and discard the 8 RH exhaust manifold studs.

Installation

NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
Clean the exhaust manifold mating surface of the cylinder head with metal surface prep. Follow the directions on the packaging.

NOTE: Hand start the studs first.
Install the 8 new RH exhaust manifold studs.
