BLEEDING POWER STEERING SYSTEM
1. Run engine until power steering fluid
reaches normal operating temperature, ap
proximately 170°F (80°C), then shut engine
off. Remove reservoir filler cap and check oil
level.
2. If oil level is low, add power steering
fluid to proper level and replace filler cap.
When adding or making a complete fluid
change, always use CM #1050017 or equiv
alent power steering fluid. Do not use trans
mission fluid.
3. When checking fluid level after the
steering system has been serviced, air must
be bled from the system. With wheels turned
all the way to the left, add power steering
fluid to level indicated on reservoir.
4. Start engine, and running at fast idle,
recheck fluid level. Add fluid if necessary.
5. Bleed system by turning wheels from
side to side without hitting stops. Maintain
fluid level just above internal pump casting.
Fluid with air in it will have a light tan or
milky appearance. This air must be elimi
nated from fluid before normal steering ac
tion can be obtained.
6. Return wheels to center position and
continue to run engine for two or three min
utes, then shut engine off.
7. Road-test vehicle to make sure steering
functions normally and is free from noise.
8. Recheck fluid level as described in steps
1 and 2.
Power Steering Gear
The optional power steering on the Corvette
is of the linkage assist type. The steering gear
and linkage is identical to that used on man-
ual steering cars. All procedures for the man-
ual gear apply to the power steering gear. A
belt-driven pump supplies hydraulic pres-
sure to a sensing valve, and then on demand
to a power cylinder on the linkage, which
provides the power assist to the linkage. See
the "Maintenance" section for adjustment
procedure.
