Power Steering Fluid (Appendix D, Item 19)
SERVICE
a.
Run engine until power steering fluid reaches
normal operating temperature, approximately 170°
F (80° C), then shut engine off. Remove reservoir
filler cap (1) and check oil level on dipstick (2).
b.
If oil level is low, add power steering fluid
(Appendix D, Item 19) to proper level and
replace
filler cap (1).
c.
When checking fluid level after the steering system
has been serviced, air must be bled from the
system.
(1) With wheels turned all the way to the left add
power steering fluid (Appendix D, Item 19) to
level indicated on dipstick (2).
(2) Start engine, and running at idle, recheck fluid
level. Add fluid if necessary.
(3) Bleed system by turning wheels from side to
side without hitting stops. Maintain fluid level
so it is just visible in the reservoir. Fluid with
air in it will have a light tan or milky
appearance. This air must be eliminated from
fluid before normal steering action can be
obtained.
(4) Return wheels to center position and continue to run
engine for two or three minutes, then shut engine
off.
(5) Road-test vehicle to make sure steering functions
normally and is free from noise.
(6) Recheck fluid level as described in steps a and b.
