AIR BLEEDING HYDRAULIC SYSTEM

If air bleeding is not complete, excessive noise in the power steering oil pump will be present.

Start the engine and run at idle.
Turn the steering wheel from the full right stop position and then to full left stop position several times. Repeat until bubbles are no longer being generated in the reservoir.
When the power steering fluid level lowers, refill the reservoir.
CAUTION: Do not allow the power steering fluid level to drop below the hatching area.
