Most power steering systems are self bleeding. To ensure your system has no trapped air, follow these steps. Install all new components. Make sure all hoses and fittings are tight and secure. Fill the reservoir. BEFORE STARTING THE VEHICLE: Raise and support the front end with the wheels off the ground. Turn the wheels back and forth to allow the steering box to draw fluid. Be sure to keep the reservoir full. When fluid level stops dropping, start the vehicle and continue turning the wheels slowly lock to lock. When the fluid level remains constant and there is no evidence of air bubbles, the power steering system is fully bled.
