Unlike some transmission fluids, power steering fluid is not manufacturer specific; any high quality power steering fluid will do.
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.

In the engine compartment,passenger side,up high by the wheel well,by your oil filter,above the side upper motor mount.It is a canister about the size of a 12oz. soda can,it has a cap that when you turn it left and remove it, it has your power steering dipstick attached to it. Fill the canister with your power steering fluid to the "full" level on the dipstick.
If you open the hood and stand in front of the engine, the power steering unit is located behind the radiator on to your left. Look at when the belts are and you will see a silver cap about 2" in diameter. Unscrew the cap and there is a dipstick on it indicating how high to fill the reservior. Use Dextron 3 automatic transmission fluid, there is no need to buy special power steering fluid. VBdenny
For the 2.7 L V6 engine, if you suspect a power steering fluid leak after doing a visual inspection, check the fluid in your PS fluid reservoir which is on the passenger side near the front of the engine bay. If it is low, and you see fluid present, you may have a leak in your PS pump or one of the power steering hoses (high pressure hose leaks are common on high mileage Optimas).This link shows good photos concerning the issue.http://kiaoptimaservice.blogspot.com/search/label/power%20steering%20pump
Power steering systems can be diagrammed into two chief components. These are the power steering pump and the rack-and-pinion steering gear. The power steering pump sends pressurized fluid into the rack which moves the gear actuating the tie-rods, which moves the wheels in the desired direction. The power steering pump has a low pressure return line and high pressure out one.
There are three reasons why you would hear a whine in power steering. The first reason is when the steering wheel is turned to far. The fluid flow to the pump is cut off forcing the pump into pressure relief. The pump has to recirculate the high pressure fluid within itself because there is nowhere for this fluid to go. If this is done to long then the fluid can heat up causing the fluid to break down and causing parts inside the pump to experience metal-to-metal contact. A second reason why whining could occur is because of an increase in the pump speed. The more fluid that is forced through the ports at a time can causes a velocity and the fluid cannot move fast enough. The vanes inside the pump cause a vacuum, which will fill with oil vapor immediately. When the vane reaches the high pressure port a vacuum cell is opened and oil rushes in to fill the void. The third reason when the oil in the reservoir really gets churned up or is low. This will allow a bubble into the pump.
If it was low recently and you filled it, it could be air in the system. The overflow can also result when pressure in the tank is too high. This is often the result of a faulty power steering pump.
Power steering has a pump driven of the engine that pressurizes hydraulic fluid to assist in moving the steering rack. Manual steering doesn't have the pump, so the effect to turn the steering wheel is high, especially at low speeds. Manual steering racks have a higher gear ratio to make it easier but an example is to turn your steering wheel with the engine off. You can get an idea of how much the pump helps.
If the car is running at idle speed while you are turning, the power steering pump has to push a lot of fluid with little power. If it sounds like a slight creaking, then it's normal. If it is a high-pitched squeal, then the serpentine belt may need to be tightened or replaced. Either way is not that big of a deal. If it is a grinding noise and you can feel a jerking motion as you turn the steering wheel, then you have a serious problem and need to take it into a mechanic.
yes and no. with the amount of room, i rotated the motor, removed the battery, and partially removed the windshied wiper fluid resoviour. You must disconnect both hoses or the power steering pump will not come out. While you have the power steering pump out, you should replace the high pressure hose.
