usually about 4 pints
There is not much difference between power steering and transmission fluid. Many people use power steering in place of transmission fluid because it is cheaper.
It depends on how much of it you have.
I paid $ 129.99 at the GM dealership for power steering flush & fill with synthetic fluid.
there should be a line where you pour the power steering fluid telling you when to stop. if there isn't it should say in your car manual.
Use a turkey baster to remove excess fluid
Probably about $3.00/pt.
Enough to fill it to the manufacturer's specification.
All brands of steering fluid are pretty much made the same. Check your automobile's manual to see if there is a certain type of steering fluid that can only be used. If not, then the brand does not matter.
There probably is no power steering fluid in the 05 Saturn. Saturn employs an electric assisted power steering system that still has a rack and pinion, but is electrically operated. A much easier, more bulletproof design in my opinion.
power steering pump is located on the left side behind the engine if you are looking head on at the car it has a dip stick to indicate how much fluid it needs.
There is no power steering in a Mercury Villager at start up in cold weather due to a failing pump or low fluid. Fluid becomes much thicker in cold weather and is much harder to pump.
Brake fluid in the oil won't be much of a problem. It probably won't hurt anything, but to be on the safe side, just change the oil. In the power steering pump it will be harder to get out. You'll have to disconnect the high pressure line and let it pump out, then re-fill it with power steering fluid.
