Warning Lights
Modern vehicles are equipped with advanced monitoring systems that can alert you to issues with the power steering system.
- Dashboard Warning Lights: If your vehicle’s onboard diagnostics detect issues with the power steering pump or fluid levels, it may trigger a warning light on your dashboard. Pay attention to any illuminated warnings, as they may require immediate attention.
Cracks or Damage
Finally, physical inspection of the power steering pump can provide visual cues indicating a problem.
- Cracks in the Pump Body: A visual inspection may reveal cracks or physical damage to the power steering pump itself.
- Worn or Damaged Hoses: Check the hoses connected to the pump for signs of wear, as damaged hoses can lead to fluid leaks and impact pump performance.
Common Causes of Power Steering Pump Failure
Understanding the underlying causes can assist you with preventative measures and maintenance. Here are several common reasons behind power steering pump failure.
Low Power Steering Fluid
One of the most straightforward causes of pump failure is simply running low on power steering fluid. Over time, fluid levels can drop due to leaks or evaporation, affecting how effectively the pump operates.
Contaminated Fluid
Another common culprit is contaminated power steering fluid. While the fluid should remain relatively clean, debris or moisture can contaminate it. If not addressed, this contamination can lead to internal wear on the pump, eventually resulting in failure.
Wear and Tear
Like all mechanical components, power steering pumps experience wear over time. Regular use, combined with factors like high temperatures and pressure, can cause the internal components of the pump to deteriorate. Eventually, this wear can result in decreased performance or complete pump failure.
Belt Issues
In hydraulic power steering systems, the pump is driven by a belt connected to the engine. If this belt becomes worn, cracked, or loose, it can impact the efficiency of the pump, leading to potential failure.
Pump Construction Quality
Lastly, the quality of the power steering pump itself can significantly affect its lifespan. Low-quality pumps are more prone to failures, often requiring early replacement. Investing in reputable brands can help ensure durability and functionality.
