Power Steering Pump
The power steering pump supplies pressure for hydraulic steering assistance.
What is Power Steering Pump?
It is belt-driven or electric. It works with fluid and hoses. Electric-hydraulic pumps run only when needed. Most modern cars have replaced hydraulic pumps with electric power steering to save fuel. Belt-driven pumps load the engine whenever it runs, while electro-hydraulic units only run when needed. A groaning noise at full lock is normal on some cars but should not be constant.
How it works
The pump generates fluid pressure.
Why it matters for your car
Whining indicates wear or low fluid. Leaks reduce assistance.
