Power Steering Total Fluid Exchange
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.
Auto Solutions provides Power Steering System Flush and equipment to clean and remove harmful
deposits and replace all of the old fluid with new. As a final step Auto Solutions Power Steering Fluid with Conditioner is added to provide total protection to the system.
