Exhaust Manifold Removal - Right Side w/o RPO NC1 or NF7

Important: It is difficult to mount the engine on an engine stand with the exhaust manifold/crossover pipe in place. When the engine is out of the vehicle, properly support the engine on the floor or bench and remove the exhaust manifold before mounting the engine on an engine stand.

Important: The EGR valve inlet pipe incorporates a crush seal connection at the water crossover. The EGR valve inlet pipe must be replaced if disconnected from the water crossover.

1. Disconnect the EGR valve inlet pipe from the exhaust crossover pipe (3).
2. Remove the EGR valve inlet pipe to water crossover bolt (2).
3. Remove the EGR valve inlet pipe (1).



4. Remove the oxygen sensor (1) from the manifold.
5. Inspect the oxygen sensor for excessive deposits or damage. Replace the oxygen sensor if necessary.



6. Remove the right exhaust manifold bolts.

Important: DO NOT reuse the exhaust manifold gasket.

7. Remove the right exhaust manifold and exhaust manifold gasket.



8. Disconnect the engine wiring harness from the knock sensor.
9. Remove the engine wiring harness from the wiring harness bracket  (1).
