DSA8056 PT 20 0027 Not All Power Steering Fluids are Created Equal All vehicles equipped with hydraulic steering systems The extreme premature failure of the power steering pump The failure is characterized by noise shaft seal leak reservoir boil over foaming in the reservoir or unexplained sideload even with an automatic belt tensioner Please note that failure can occur as quickly as 20 30 minutes after pump installation Use of substandard power steering fluid that lacks the additives necessary for proper lubrication of the power steering pump more specifically additives such as viscosity improver friction modifiers and anti foaming agents Use of substandard fluids causes both the fluid and system to overheat and the pump bushing to breakdown At this point the pump is no longer capable of holding pressure resulting in total loss of assist Use an OE recommended or equivalent fluid for complete system replacement and top offs Refer to the vehicle manual or an OE vehicle information system Mitchell s Alldata etc to find the recommended fluid for your application A fluid that meets OE standard typically has specifics printed on the label Fig 1 A general statement claiming the fluid meets OE requirements does not guarantee good fluid quality Fig 2 Power steering fluid does not have an API American Petroleum Institute certification and therefore does not have minimum standards associated with its production The only standards established for power steering fluid come from the OEM If you are uncertain as to the quality of the Power Steering Fluid you are using let CARDONE provide peace of mind Please refer to our list of recommended fluids found at www cardone com Problem Cause Solution Note Application Damaged Bushing Caused by Improper Lubrication Substandard Fluid Normal Bushing Wear when Properly Lubricated OE Recommended Fluid On Car Test Results Fig 1 Fig 2
