You will need a special service tool (SST) for this repair.
First, remove the upper fan shroud. Then remove the fan clutch assembly in a counterclockwise direction using a fan clutch wrench (this is the SST). Remove the fan clutch assembly from the vehicle.
Remove the fan blade mounting bolts.
Remove the fan blade from the fan clutch.
I believe the '97 and up models are non-interference engines. A quick call to local Chevy dealer can confirm this.
