1) Turn ignition off. Raise and support vehicle with wheels
off ground. Turn wheels fully to left. Add power steering fluid to
FULL COLD mark on dipstick. Leave cap off. Turn wheels from side to
side several times, but DO NOT touch steering stops. Add fluid, if
necessary, to maintain level at FULL COLD mark.
2) Start engine. With engine idling, recheck fluid level. Add
fluid, if necessary, to bring level to FULL COLD mark. Install cap.
Return wheels to center position. Lower vehicle. Continue to run
engine for 2-3 minutes. Road test vehicle. Check for leaks. Ensure
fluid level is at FULL HOT mark when fluid stabilizes at operating
off ground. Turn wheels fully to left. Add power steering fluid to

Well they said they can't bleed it and there is no pump for it, that the only way to do it is to move the wheels and it will work its way out. Today I put it up on the stands and popped the cap and there was some small bubbles but I couldn't get them to go away completely. What should I do hahah

As per my Service Manual:
Bleeding the Power Steering System
Tools Required
J 35555 Mity Vac
J 43485 Power Steering Bleeding Adapter
Important: Hoses touching the frame, body, or engine may cause system noise.
1. Verify that hoses do not touch any other part of the vehicle
Important: Loose connections may not leak, but could allow air into the steering system.
2. Verify that all hose connections are tight.
Important: Maintain the fluid level throughout the bleed procedure.
3. Remove the pump reservoir cap.
Notice: If the power steering system has been serviced, an accurate fluid level reading cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time.
Notice: When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.
Important: Use clean, new power steering fluid only.
4. Fill the pump reservoir to the FULL COLD level.
5. Attach the J43485 to the J35555 or equivalent.
6. Place the J43485 on or in the pump reservoir filler neck.
7. Apply a vacuum of 68kPa (20 in Hg) maximum.
8. Wait 5 minutes. Typical vacuum drop is 7-10kPa (2-3 in Hg). If the vacuum does not remain steady, refer to Excessive Vacuum Drop Diagnosis at the end of this procedure.
9. Remove the J43485 and the J35555.
10. Reinstall the pump reservoir cap.
11. Start engine. Allow engine to idle.
12. Turn off the engine.
13. Verify the fluid level. Repeat steps 11-13 until the fluid stabilizes.
Important: DO NOT turn steering wheel to lock.
14. Start the engine. Allow the engine to idle.
15. Turn the steering wheel 180-360 degrees in both directions 5 times.
16. Switch the ignition to off.
17. Verify the fluid level.
18. Remove the pump reservoir cap.
19. Attach the J43485 to the J35555 or equivalent.
20. Place the J43485 on or in the pump reservoir filler neck.
21. Apply a vacuum of 68kPa (20 in Hg) maximum.
22. Wait 5 minutes.
23. Remove the J43485 and the J35555.
24. Verify the fluid level.
25. Reinstall the pump reservoir cap.

DESCRIPTION & OPERATION
NOTE: Some vehicles are equipped with Variable Effort Steering
(VES) system, identified by a solenoid on the power steering
pump at the pressure line outlet. See appropriate ELECTRONIC
article.
RACK & PINION ASSEMBLY
Pump pressurizes fluid and sends it through the pump’s flow
control valve to the pinion and valve on the rack and pinion assembly.
See Fig. 1. Pinion and valve direct fluid to either side of the piston
and rack, depending on turning direction of steering wheel. Piston and
rack converts hydraulic pressure into linear force, reducing turning
effort.
POWER STEERING PUMP
Two types of power steering pumps are used, CB series or TC
series. These pumps are constant displacement vane-type pumps. See
Fig. 4 and Fig. 5. When pressure exceeds set limits, a flow control
pressure relief valve opens, allowing fluid to return to the inlet
side of the pump. Some pump applications have remote fluid reservoirs
or reservoir attached to pump assembly, to enable different pump
mounting locations. Some models have a reverse rotation pump,
depending upon location and belt routing.
LUBRICATION
FLUID TYPE
Use GM Power Steering Fluid (1050017). Failure to use proper
fluid will cause hose and seal damage, resulting in fluid leaks and
damage to pump and/or rack and pinion assembly.
