Even the most mechanically challenged auto owners realize the need to visit their auto repair shop for an oil change a few times a year, but are often clueless as to what other fluids are in their vehicle or what maintenance needs to be done to them.  Power steering fluid is one of those often overlooked fluids but yes, it too needs some TLC every now and again.

So what does power steering fluid actually do?  Well, simply put, it is essential to the smooth operation and ease of your steering; without it, you will be expending a lot more energy and force to try and turn your wheels.  Power steering itself works by utilizing a hydraulic pump which is mounted on the engine, the fluid in the pump is held under pressure until the driver turns the wheel and then it is released into the steering system and the pressure gives that extra power to steer smoother and easier.

Over time however, this fluid can become contaminated with bits and pieces of worn out seals or O-rings and like most other fluids can begin to break down as well.  When this happens, the hydraulic pump has to work harder and it can eventually chew up your pump and it will have to be replaced which can cost several hundred dollars.  Contaminated power steering fluid can also damage the rack in the steering system which is a huge expense to replace.

The fluid is by far the least expensive component of your power-steering system and changing it at regular intervals will help to prolong the life and integrity of your power steering system.  It is possible to change it yourself but it does require more knowledge and expertise than changing your oil so this is one of those maintenance items you might want to leave to your auto mechanic.

It is a good idea however to check the level of your power steering fluid about once a month when you check the levels of your other essential fluids.  If you notice that it is low or seems to be lower each time you check it, you might have a leak.  You will definitely need to make a trip to your auto repair shop and get it checked out because if you run out of fluid, not only will it be almost impossible to steer your vehicle but it can cause catastrophic damage to the steering system.
