THE PROBLEM

Experts recommend periodic flushing or fluid exchanges of power steering systems. All suppliers of re-manufactured or replacement power steering racks recommend flushing the entire system of old fluid and contaminants when replacing a power steering rack.

Historically, power steering system fluid service has been neglected, often due to the lack of a convenient method for providing such flush or fluid change services. Previous methods for flushing the power steering system or replacing the power steering fluid were time consuming and often inefficient or incomplete.

Service neglect leads to power steering system complaints including poor handling, hard or sluggish steering, and objectionable noise. These complaints can often be attributed to fluid that has thickened due to oxidation, become contaminated or undergone additive degradation over time. Fluid that has thickened due to oxidation often results in hard steering when the fluid is cold. This commonly results in a phenomenon called “morning sickness.” Also, over time, fluid leakage from power steering system seals can often be attributed to seal deterioration from continued contact with degraded fluid.

Previously, power steering fluid exchange, without the use of a machine, was accomplished by disconnecting a low pressure hose and gravity draining the old fluid, then reconnecting the hose and refilling the reservoir with new fluid. Such gravity draining did not flush the old fluid from small passages or pockets in the system where old contaminated fluid would settle, resulting in a very incomplete fluid exchange.

THE SOLUTION

The Wynn’s® Power Steering Flush Machine is a portable, lightweight, easy to operate and efficient unit that flushes the system of old fluid and contaminants, and refills the system with new fluid. This machine is designed to be used with vehicles containing either conventional power steering fluid or ATF type power steering fluid in the power steering system.

The basic flush and refill procedure is performed via the power steering fluid reservoir and includes the following:

• Draining the old fluid from the reservoir.
• Refilling the reservoir with Wynn’s Power Steering System Flush.
• Performing the flush process with simultaneous use of the suction hose and the supply hose.
• Performing the new fluid refill process with simultaneous use of the suction hose and the supply hose.

Routine power steering fluid service is designed to extend the life of power steering system components. The Wynn’s Power Steering Flush service helps prevent component wear, keeps seals conditioned to help eliminate leaks, and provides the appropriate fluid viscosity for maximum power steering system performance.

Note: Read and follow the Operating Instructions completely.

Caution: The Wynn’s 2-part flush kits No. 10176 and No. 10179 are not recommended for use with Honda or Audi vehicles. Wynn's® Type H/A Power Steering Fluid Kit No. 11001 is recommenced for Honda and Acura vehicles. Always verify the proper type of power steering fluid before performing this service.
