How to replace the Exhaust Heat Shield on the LL8 (4.2L) exhaust manifold on Chevrolet Trailblazer?

The first step to change the Exhaust Manifold heat shield on the ll8 (4.2L) involves removing the air cleaner outlet resonator. The first step requires you to disconnect the transmission filler tube stud nut attached to the secondary air injection adapter before moving the filler aside. Uninstall the oil level indicator tube from the system. The next step requires removing the Oxygen Sensor that connects to the Exhaust Manifold. Drain the shield by removing its four manifold mounting nuts before extracting the heat shield from the manifold. When installing the heat shield on the Exhaust Manifold secure its four nuts with a torque of 10 nm (89 lb in). Begin by installing the Oxygen Sensor and then proceed with the installation of the oil level indicator. The transmission filler tube stud requires a secure attachment of the tube through its associated nut tight to 10 nm (89 lb in) tension. As the last step install the air cleaner outlet resonator.
