Power Steering Fluid

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system
or you hear an unusual noise. A fluid loss in this
system could indicate a problem. Have the system
inspected and repaired.
See "Engine Compartment Overview" in the Index for
more information on location.
