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.

SOURCE: how to adjust parking brake on a GMC Sierra 2500

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.

  3. Relieve the fuel system pressure.
  4. Drain the fuel tank.
  5. Remove or disconnect the following:
    • Fuel tank
WARNING Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

  • Fuel sender assembly retaining ring using a fuel tank sending unit wrench. Remove the fuel sender assembly and the seal. Discard the seal.
  • Note the position of the fuel strainer on the fuel sender. Support the fuel sender assembly with one hand and grasp the strainer with the other hand. Pull the strainer off the fuel sender. Discard the strainer after inspection. Inspect the strainer. Replace a contaminated strainer and clean the fuel tank.
    • Fuel pump electrical connector
    • Electrical connector retaining clip from the fuel level sensor
    • Sensor electrical connector from under the fuel sender cover
    • Fuel level sensor retaining clip
  • Squeeze the locking tangs and remove the fuel level sensor.

      • New seal on the fuel tank
      NOTE The fuel pump strainer must be in a horizontal position when the fuel sender is installed in the tank. When installing the fuel sender assembly, assure that the fuel pump strainer does not block full travel of the float arm.

    SOURCE: how to charge dual batteries

    There should be a bridge mounted close to the main battery. Make sure that bridge is on. Now connect your charger to the main battery. This will charge both batteries evenly.

    I just replaced the O2 sensor behind the cat on the passenger side. I was told to check the fuse as well. The truck is a 2006 GMC Sierra 2500 HD. I have no idea what fuse needs to be checked. I can't...

    there isn't a seperate fuse for the o2 sensors as such, they are controlled by the PCM. The fuses are listed on the inside of the box under the hood.
