Special Tool(s)
CAUTION: If the air is not purged from the power steering system correctly, premature power steering pump failure could result. This condition can
occur on pre-delivery vehicles with evidence of aerated fluid on vehicles that have had steering component repairs.
1. NOTE: A whine heard from the power steering pump may be caused by air in the system. The power steering purge procedure must be performed
prior to any component repair for which power steering noise complaints are accompanied by evidence of aerated fluid.
Remove the reservoir cap. Check the fluid.
