What is a common symptom of low power steering fluid?

A common symptom of low power steering fluid is a whining noise when steering. This noise occurs because the power steering pump is struggling to generate the necessary pressure to assist with steering. As the fluid level drops, the pump may have to work harder, which can lead to a faint or pronounced whining or screeching sound, especially when the steering wheel is turned. This is a clear indication that the fluid needs to be replenished to ensure proper function of the power steering system.

Recognizing this symptom is crucial for vehicle maintenance, as ignoring it can lead to more severe issues, such as pump failure, which can be both costly and dangerous while driving. Understanding how the power steering system operates helps diagnose the problem accurately, emphasizing the importance of monitoring fluid levels for optimal performance.
