Power steering service

Routine maintence June 13, 2013

Today weíre going to talk about power steering service in Chicago. If you took an informal poll around Chicago youíd probably find that most have never heard of power steering service. Thatís not surprising. Even though power steering is standard on every vehicle, most people in Chicago arenít aware that it needs periodic service.
If youíre younger than a certain age, youíve probably never driven a car or truck without power steering. To get an idea of the difference; if youíve ever cut a board with a hand saw, you know itís a lot of work. Using a power saw is easy-peasy by comparison.
Without power steering, your arms have to do all the work to steer the wheels, and thatís hard, especially around downtown Chicago. Thatís why old cars had such big steering wheels; to get enough leverage to steer.
Most vehicles in Chicago have a hydraulic power steering system. The serpentine belt from the engine powers a pump. The pump pressurizes the power steering fluid. This actuates a hydraulic cylinder that provides power to help steer.
Some vehicles in Chicago use an electric pump to pressurize the fluid rather than a belt driven pump. Weíre also seeing vehicles with electric motors providing the power assist, not using power steering fluid at all. Weíll see a lot more electric systems as more hybrids and electric vehicles hit the market.
At least for now, the vast majority of power steering systems use power steering fluid that needs to be serviced. The fluid needs to be changed for a couple of reasons. For one, it attracts moisture. Water has different hydraulic qualities than power steering fluid, and that makes a difference in steering performance. Water is also corrosive and can damage power steering components. The fluid also just gets dirty and needs to be changed. Removing the old fluid and flushing out the system gets rid of dirt and deposits. The clean, fresh fluid lubricates and provides better corrosion protection.
So ask your Chicago service adviser at Triangle Auto Service or check your ownerís manual to see when power steering service is recommended. Itíll extend the life of your power steering components.
