To bleed the Power Steering system on any Celebrity:
Raise the car up so the wheels are slightly off the ground. Then with the motor off make sure the reservoir on the power steering pump is full and then turn the wheels as far as they will go from one side to the other. Do this about 10 to 12 times. Check the reservoir from time to time to make sure it stays full That will circulate the fluid through the system thus bleeding out any air.
The squeal is often caused by the power steering belt slipping. Check the serpentine belt to see if it needs replacement.
