What is it?
Power steering fluid is the hydraulic fluid used in the steering system to create a link between the steering wheel and the front wheels. Hydraulic presses put pressure on a small amount of fluid (Power Steering Fluid) in order to generate a large amount of power.
What does it do?
Hydraulic systems like these decrease the amount of effort required to turn the wheels. Power steering fluid also lubricates the moving parts within the steering system. It suppresses foaming and prevents corrosion in the power steering gear and steering pump, which keeps vehicles working optimally.
Typical Wear and Tear
The best way to know when your power steering fluid should be changed is to follow the original equipment manufacturer (OEM) guidelines. Generally, power steering fluid should be replaced at least every five years or 50,000 miles.
