How to Replace the Upper Fan Shroud with RPO M74 on Chevrolet Silverado 3500?

The process of Fan Shroud w/m74 replacement begins by releasing the air cleaner outlet duct clamps from Throttle Body and mass airflow sensor before duct removal. The replacement process begins with removing the a/c line retainer from the Fan Shroud as well as the engine harness clip from the pcm cover and then proceeding to remove the tcm cover bolts before taking out the tcm cover. Begin by disconnecting the tcm electrical connectors through the loosening of their connector bolts and completely remove both the tcm and its cover from the rest of the system. Starting with the removal of Fan Shroud retainers and bolts allows accessing the upper Fan Shroud. Install the upper Fan Shroud properly in its position while securing Fan Shroud bolts at 9 nm (80 inch lbs.). Reinstall the tcm while connecting its electrical connectors and securing the tcm electrical connector bolts to 8 nm (71 inch lbs.). Fasten the tcm cover against the Fan Shroud by tightening bolts to 9 nm (80 inch lbs.). Replace the engine harness clip alongside the pcm cover then install the a/c line retainer to the Fan Shroud and the air cleaner outlet duct on its intended position. Swing the last phase of the maintenance by adjusting the air cleaner outlet duct clamp screws until they reach 7 nm torque where the screw torque is equivalent to 62 inch lbs.
