How does aging affect power steering fluid?

The correct answer focuses on the fact that aging in power steering fluid can lead to reduced effectiveness and can potentially cause system failure if the fluid becomes contaminated. Over time, power steering fluid can break down due to exposure to heat, air, and contaminants such as metal shavings or rubber debris from the seals and hoses within the system.

As the fluid ages, its ability to lubricate and protect the power steering components diminishes. This can lead to increased wear on the pump, rack, and pinion, and other associated parts, ultimately resulting in failure of the power steering system. Furthermore, if this fluid becomes contaminated with dirt or other foreign materials, the risk of system failure increases significantly.

Understanding this characteristic of aging power steering fluid is crucial for proper vehicle maintenance and ensuring optimal performance of the steering system. Regular checks and fluid replacement can help prevent issues related to fluid degradation and contamination.
