In checking for power steering fluid leaks, what should be observed during the inspection?

Observing steering components while a helper turns the steering wheel is essential for checking for power steering fluid leaks because this action allows for the dynamic inspection of the entire system under operational conditions. When the steering wheel is turned, the power steering pump engages, pressurizing the system, which can help reveal leaks that might not be visible when the system is not under load. Fluid may escape from hoses, fittings, or other components as they flex or shift during operation, exposing potential weaknesses. This hands-on approach provides a more thorough assessment of the system’s integrity and can help identify issues that might not be apparent during a static inspection.

Other options suggest a more limited examination, focusing solely on hoses or fittings, or even recommending fluid changes before testing. Such approaches might miss leak sources that could only be detected when the system is activated, making them less effective for thorough diagnostics.
