How do i replace the serpentine belt on a 2005 gmc sierra 2500 6.0

Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off
