SOURCE: 2007 gmc sierra 2500 IAT sensor
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.

The adjuster is just like on a car with drum brakes. It can be adjusted with the wheels still on the truck, but if yours is out enough that it doesn't work, an inspection is warranted. Axle seal failure is common and will soak the shoes.
Jacked both rear wheels off ground, and while slowly spinning wheel, tighten the star-wheel adjuster until you just hear and feel brake drums rubbing, then loosened slightly.
There's a plastic dust cover about 1/4" X 1" that you remove, and use a drum brake adjuster tool.
The driverside access hole is below axle, easily accessable. To tighten driver side rear parking brake, turn star-wheel adjuster down.
The passengerside access hole is found above axle, and difficult to see. Removed pass side wheel and used an inspection mirror.
To tighten passenger side rear parking brake, turn star-wheel adjuster up.
Good luck and hope this helps. Oh and the other thing to is that if you do smell axle fluid around the wheels and see oil leaking from the drum area. Then you have a axle wheel seal and or bearing gone bad too.

ITS A SPIN ON FILTER, YOU NEED TO DISCONNECT THE WATER SENSOR ON THE BOTTOM OF THE FILTER, THEN USING A STRAP FILTER WRENCH LOOSEN THE FILTER AND SPIN IT OFF.
CHECK THE FILTER HOUSING TO BE SURE THE INNER FILTER SEAL ISN'T ON THE HOUSING AND CAME OFF WITH THE FILTER.
REMOVE THE WATER LEVEL SENSOR AND DISCARD THE SEAL.
INSTALL THE WATER LEVEL SENSOR ON THE NEW FILTER. USING A LITTLE GREASE ON THE INNER FILTER SEAL AND ON THE OUTER O-RING TO HOLD IT IN PLACE, SPIN ON THE NEW FILTER.
OPEN THE VENT ON THE UPPER SIDE OF THE FILTER HOUSING. PUSH DOWN ON THE HAND PUMP QUICKLY UNTIL THE FUEL IS COMING OUT OF THE VENT. CLOSE THE VENT AND PUMP THE FILTER PUMP UNTIL IT FEELS SOLID. AT THIS POINT START THE ENGINE. IF IT STALLS PUMP IT UP AGAIN AND RESTART THE ENGINE. IF YOU HAVE AN ASSISTANT THEY CAN PUMP THE FILTER PUMP WHILE THE ENGINE IS RUNNING AND QUIT WHEN YOU FEEL THE ENGINE IS NOT GOING TO STALL. ABOUT 10 TO 15 SECONDS USUALLY WORKS.
CHECK FOR LEAKS.
BEFORE STARTING THE ENGINE USE BRAKE WASH TO REMOVE THE FUEL SPILLED DURING THE FILTER REPLACEMENT. ALLOW IT TO DRY BEFORE STARTING THE ENGINE.
RATE ME PLEASE.

Enjoy this...jack up truck, remove tire, remove plastic cowling and expose front right wheel well.you may want to wash this side of engine at this point. Remove battery cables, remove the 13 mm nut and 8mm nuts on the solenoid. take a 15mm socket and remove the upper aand lower holding bolts. Use an extra long extension for the lower bolt. Ratchet out in front of the A-arm. Dislocate the starter from the fly wheel side of starter. wiggle,jiggle and point the starter gear at a 45 down and PULL starter out and down.
