Hi xboxxer,
You should be able to find a copy of the Owners Manual at my.chevrolet.com. If you want to provide the last 8 digits of your VIN we can look more into this for you.

the ecm turns the low speed fan on at coolant temps of 103*C to 108*C. the high speed fan will turn on above 108*C.
the coolant warning indicator comes on at 128*C
the ecm will also turn the high speed fans on when the a/c is engaged.
