In the hydraulic power steering system used in the vast majority of vehicles today, fluid must be pumped through a series of lines and hoses to the steering rack. This is done by the power steering pump - without it, it is impossible to move fluid or provide power steering.

The power steering pump is located on the side of the engine near the power steering fluid reservoir. It is driven by a V-ribbed belt that also powers other parts of the engine including the alternator, air conditioning compressor and more.

Your car's power steering pump runs all the time if the engine is running, but it is put under extra stress when you turn the steering wheel (when it pumps high-pressure fluid in the line to the rack to increase steering power). you need). These pumps have no real life, and in theory yours could last as long as a car with proper maintenance. With that said, they don't usually last past 100,000 miles and pump failures at lower miles are not uncommon.

Other problems that can be confused with a power steering pump failure include a stretched, worn, or broken poly V-belt, low power steering fluid, and damaged/seized pulley bearings (the pulley that drives the power steering pump).

If the pump fails, the entire power steering system will be disabled. It's not as scary as it might seem, if you're ready for it. You will still be able to drive the car. It just takes more effort to turn the steering wheel, especially at lower speeds. Of course, this is not something you really want to experience, especially if the pump fails and takes you by surprise. Therefore, it makes sense to be aware of a few signs and symptoms that may indicate that your pump is on the verge of failure. These include the following:

• Howling from the pump when turning the steering wheel (may be more pronounced at lower or higher speeds)
• Pump knocking
• Screeching or groaning from the pump
• Noticeable lack of power steering assistance when turning the steering wheel

If any of these symptoms are present, it is important to have the pump checked and replaced if necessary. A certified mechanic can help inspect your power steering system and replace or repair the power steering pump pulley as needed.
