What fluid is used in a 1965 impala convertible pump?

A 1965 Impala convertible uses power steering fluid. It's important to note that it's not just any fluid; it should be a power steering fluid specifically designed for use in older vehicles. Using the wrong type of fluid can damage the power steering system. Check your owner's manual (if you have it) or consult a reputable auto parts store for the correct type of power steering fluid for your classic car.
