Bleeding The Power Steering System
WARNING: This page is about a different car, the 2002 Isuzu Rodeo and 2002 Honda Passport. However, it is still accessible from the selected car via links, so may be relevant.
When a power steering pump or unit has been installed, or an oil line has been disconnected, the air that has entered the system must be bled out before the vehicle is operated. If air is allowed to remain in the power steering fluid system, noisy and unsatisfactory operation of the system may result.
