8.2.	One bolt from the rear bracket

8.3.	Three bolts from the front of the power steering pump

The bolts are accessible through the holes in the power steering pump pulley.

9. Remove the oil level indicator tube. Refer to Oil Level Indicator and Tube Replacement in Engine Mechanical-2.2 L.



10. Remove the secondary air injection pipe mounting nuts (1, 2).
11. Remove the air injection pipe from the exhaust manifold.



12. Remove the exhaust manifold nuts.
13. Remove the exhaust manifold.
14. Remove the exhaust manifold gasket.



15. Remove the heat shield, if replacing the exhaust manifold.
16. Clean the exhaust manifold mating surfaces. Refer to Exhaust Manifold Cleaning and Inspection in Engine Mechanical - 2.2 L Unit Repair.

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.
