Chevrolet Captiva Service & Repair Manual: Power Steering System Bleed
| Use clean, new power steering
fluid type only. |
| Hoses touching frame, body or
engine may cause system noise. Verify that hoses do not touch any other
section of vehicle. |
| Loose connections may not leak,
but could allow air into steering system. Verify that all hose connections
are tight. |
| Power steering fluid level must
be maintained throughout bleed procedure. |
| With hydro-boost only, oil level
will appear falsely high if hydro-boost accumulator is not fully charged.
Do not apply brake pedal with engine OFF. This will discharge hydro-boost
accumulator. |

system level, "FULL COLD" level, or middle of hash mark on cap stick
fluid level indicator. |

from stop to stop 12 times. Vehicles equipped with hydro-boost
systems or longer length power steering hoses may require turns
up to 15-20 stop to stops. |
| 5. |
Verify power steering fluid level per
operating specification. |
| 6. |
Start engine. Rotate steering wheel
from lefthand to righthand. Inspect for signs of cavitation or fluid
aeration (pump noise/whining). |
| 7. |
Verify fluid level. Repeat bleed procedure,
as required. |
