Re: Power steering pump problem
Welcome to the, garage.
Where is the fluid leaking? Indeed the hydraulic cooling fan is fed by the power steering pump. The pump makes a whining noise when its low on fluid. Dont operate it for prolonged time, because it will ruin the pump.
Probably by solving the leak, you will solve your problem.
Bleeding is done by just moving the steering wheel from stop to stop around 20 times, while you keep the reservoir full. In the beginning it will form a lot of bubbles, so just shut down the engine and wait a few minutes for the foam to disappear.
