The GM Techline instructions say to fill the power steering pump reservoir to the cold mark, start the engine, and firmly/fully apply the brakes 10-15 times.
Shut off the engine, check/fill the power steering reservoir back to the cold mark.
With the engine off, lift the front axle off the ground and turn the steering wheel lock to lock 15-20 times.
Check/fill the fluid.
Start the engine and slowly turn the wheel lock to lock twice while listening for signs of air pockets/cavitation (pump noise/whining).
If there are signs of cavitation, repeat the bleed process. If there are still signs of cavitation, inspect hoses and connections for leaks.
