If your power steering pump is going out and you add power steering fluid to it, the fluid will not fix the underlying issue with the pump itself. Adding fluid may temporarily alleviate symptoms of a failing pump, such as noisy operation or difficulty steering, but it will not address the root cause. Continuing to drive with a failing power steering pump can lead to further damage to the pump as well as other components in the power steering system. It is advisable to have the power steering pump inspected and repaired or replaced by a qualified mechanic to ensure the proper functioning of your vehicle's power steering system.
