If you want to CYCLE completely, just remove the RETURN line (low pressure hose) from the pump, and pour ATF+4 into the reservoir, while the other fluid is pumping out into something... Then when you see a color consistency FROM the return, STOP. Hook it all back up, restart engine, check leaks, and top off...
You can use this as a guide:
1. Turn off the engine.
2. Jack up the front end and put the car on jack stands.
3. Wrap some plastic around the pulley of the power steering pump and the nearby belt surfaces, as the close proximity of the pump fittings may otherwise result in ATF coming into contact with the belt, and this can cause the belt to slip.
4. Open the reservoir and use a syringe to remove the fluid from the reservoir (have used a spray bottle trigger/pump).
5. Open the banjo fitting on the pump and let the fluid drain out into a pan positioned below it.
6. Turn the ignition key to unlock the steering wheel (but do not start the engine), then rotate the wheel slowly lock to lock a few times to push the old fluid out of the system. When done, the reservoir should be completely empty and no additional fluid should drain from the fitting.
7. Remove the hollow bolt and install new crush washers on the banjo fitting. Note: You need not install new crush washers if you expect to repeat this procedure during this maintenance session to further flush the system. Just make sure you use new crush washers before you button the system up for good.
8. Torque the banjo fitting to to 40Nm or 30 ft*lbs. At least on my car the bumper fairing gets in the way of using a torque wrench with a fixed head. My pivoting head torque wrench was able to do the job, but I had to adjust the torque for the offset. If you don't have a torque wrench, you can just tighten the bolt until you feel the crush washers start to absorb the torque and then STOP. Do not overtorque the fitting.
9. Remove the protective plastic from the accessory belt, being careful not to contaminate the belt in the process.
10. Refill the reservoir using the dipstick minimum and maximum markings as a guideline. Do NOT overfill it. You may notice some large air bubbles come to the surface in the reservoir as you fill it. This is due to the fluid displacing the air in the hoses and is expected.
11. Rotate the wheel slowly lock to lock. As you turn the wheel, the level in the reservoir will drop. Continually add fluid so you don't run it dry, and do this until the level in the reservoir no longer drops. Fill the reservoir to a level between the minimum and maximum marks on the dipstick. Do NOT overfill it.
12. Reinstall the reservoir cap and hand-tighten.
13. Start the engine and rotate the wheel slowly lock to lock. The wheel should be turned at a rate that lock to lock is achieved in about 10 seconds or more. Do this 10 times and then center the wheel and shutdown the engine. Don't hold the wheel against the lock! When you reach the lock immediately reverse direction.
14. Stop the engine, reopen the reservoir, and examine the dipstick. If the level is below the minimum, add fluid to reach the middle of the range indicated on the dipstick.
15. Examine the fluid quality in the reservoir. If you see a lot of small bubbles you have successfully removed some of the air from the system. If the fluid is a normal dark red color and no bubbles are present, and/or the level has not dropped, you may have removed all the air. Even in this case, I recommend you bleed the system twice for safety's sake.
16. Repeat the process from step 11 until the level in the reservoir no longer drops.
