Fill with fluid... crank it up, turn it lock to lock until the air is out.

Finally paid off...

well you don't really need it running.. you could just turn it lock to lock.. i leave the cap off... just to add more fluid.

Your first initial bleeding of steering pump should be without engine running!Lock to lock at least 30 times. This will allow fluid to start lubricating pump after so you can start an continue rotating until all air has been purged from system! Oh yea forgot to mention like Jerry said... Have tires lifted of ground when doing the bleeding!

Mine is constantly bled through the mysterious leak in it...

I've heard 25 lock to lock will get all air out and fluid in, but i'd take the advice on the 30, just for safe measure...

Do NOT (!!) start the engine for the initial bleeding!! Doing so will cause cavitation inside the power steering pump and damage the pump vanes. Jack up the front-end so the weight is off the front tires and without the engine running, turn the steering wheel back and forth (lock to lock) at least 25-30 times. Once that is completed and you have topped off the power steering fluid reservoir, then you can start the engine and drive it. Stop after a short while and check the fluid level and add more fluid if needed and you're done.

Getting Savvy...

When you have a choice, buy American.

There may be a teflon washer that is one time use on the pressure hose fitting. It should be replaced EVERY time the fitting is removed. (It comes with new pumps) If not that, it'll be an o-ring.

if your line had some white plastic looking stuff that fell off when the old pump was removed... it's the teflon 'washer' style.

The technical advice you get from me here is worth exactly what you paid me for it. Warranty issues will be reimbursed at double what you paid me for the advice.
