Serpentine belt installation for 2003 GM p/up truck: No codes

Question:

This truck's engine serpentine belt was sqealling and before I could replace it, it broke on me, how do you replace it?

ATS Advisor:

If you open your hood compartment of your truck (see picture) you will see the diagram of the serpentine belt routing. You can follow that and when you buy a new one, the package of the belt will also show a diagram for it. Make sure you give the parts store the accessories that you have like AC so they can give you the right lenght of belt.
