What is required when replacing a power steering pump, according to best practices?

When replacing a power steering pump, flushing the entire system is considered best practice to ensure optimal performance and longevity of the new pump. This process removes any existing fluid, debris, and contaminants that may be present in the system. Mixing different types of power steering fluid or using contaminated fluid can lead to poor steering response and potentially damage the new pump or other components of the steering system.

Flushing the system ensures that the new fluid is compatible with the pump’s specifications and helps prevent any issues that might arise from old, degraded, or incompatible fluids. This is especially important because power steering systems often have specific fluid requirements based on the vehicle make and model. Therefore, performing a complete flush is vital to maintaining functionality and reliability in the steering system.
