Which component is typically inspected first when diagnosing a fluid leak in a power steering system?

In diagnosing a fluid leak in a power steering system, the first component typically inspected is the power steering fluid reservoir. This is because the reservoir is often at the highest point in the system and can provide immediate visibility of fluid levels and potential leaks. Inspecting the reservoir allows technicians to identify whether there is a loss of fluid and can help pinpoint where the leak might be occurring based on the fluid's location and condition.

Once the reservoir is checked, components such as the high-pressure hoses, pump, and steering gear can be evaluated based on findings from the initial inspection. The high-pressure hose connection is critical, but if the reservoir is not addressed first, you might not have a clear understanding of the fluid's origin and extent of the leak.

Therefore, starting at the power steering fluid reservoir provides a logical and effective approach to diagnosing leaks in the system.
