Oil changes and radiator flush & fills are among the more common types of auto maintenance that drivers perform, but these aren't the only fluids in a vehicle. Power steering fluid is also present on all modern cars, as it assists the driver with turning the steering wheel. While the fluid typically lasts for the life of the car, in some instances it may need to be replaced due to contamination or a small leak, according to Yahoo! Autos.
If you've noticed it becoming more difficult to steer lately, the power steering fluid would be a good place to check. Typically, this reservoir will include some kind of lettering to indicate it houses power steering fluid.
It can be difficult to see inside the tank, so you may need to use a paper towel to dab a bit of the fluid. The color varies, but it is generally red, pink, amber or clear. Signs that the fluid may be contaminated include dark brown or black coloration. In this case, the fluid should be replaced immediately.
Issues with power steering fluid could indicate more serious car repairs, such as with the steering rack or pump, so it's not a bad idea to take your vehicle in to an auto maintenance expert if you notice an issue.
