The pump fluid is also a lubricant. And as the pump wears down over the years, there could be metal particles in the fluid. There is also the possibility that there may be moisture in the fluid. Draining and refilling it starts with fresh fluid so that the pump lasts longer. Same with the engine oil, engine coolant, dual pump fluid and transmission fluid--just because a car doesn't drive any different, doesn't mean the oil or coolant didn't need to be changed. It's just a way to make sure you get the maximum life out of the components. Or to look at it another way, cheap insurance. So no worries--even if you don't feel a difference, you did the right thing! ?What would go wrong with too old steering fluid? How could you tell?
I just have the steering fluid replaced at the dealer by dealer recommendation, but I didn't feel anything different in the steering after the flush.
That is probably a good sign (as long as they did indeed change the coolant & power steering fluid), because they should not feel or perform any different. Coolant is designed to keep the engine from overheating in hot weather & freezing in cold weather. Automotive fluids typically wear out over time, get dirty from the systems they flow through (thereby contributing to more wear - sort of like wet sanding), and can absorb water (brake fluid) which contaminates the fluid.What would go wrong with too old steering fluid?

Exactly the same happened with the coolant. The car never heated up neither before nor after the flush. even in Florida's summer.
I did feel a difference when the brakes fluids was flushed. I felt the brakes more reactive.
My V is a 2008 with 50k miles. I got it six years ago with 20k miles.
