Check out the 2 lines that run from your power steering pump. With the engine running try moving them, and look for fluid leaking around the end of the hoses, you will probally find one of them leaking at the fitting. Of course be careful with the engine running, do not have any rags or anything in your hands around a running engine.

Power steering leaks from the cap


could be overfull
remove excess to the full mark on the dipstick
could be a problem power steering pump bypassing excessive oil back to the reservoir under pressure and heating and expanding the oil
take it to an accredited power steering service center and have a pressure test done on the pump
the humming noise indicates a valve problem leaking under pressure

Where do you check the power steering fluid? I think mine is leaking if it is reddish in color.


There is a reservoir attached to your power steering pump, which is mounted on the front of your engine. A stick gauge is attached to the reservoir cap when you remove it. Add the proper power steering oil directly into that reservoir if needed. Do not overfill, respect gauge mark.

If it's a power steering fluid leak, most probable it comes from a bad seal of your steering box pitman arm shaft. If it's the case, you can verify it, looking from under the vehicule, the bottom of your gear box will be covered of dirty oil.

However, reddish color fluid leak could also come from the cooling circuit of your automatic transmission or from the pan of your transmission. In conclusion, a visual check by under the vehicule will help to diagnose the origin.
Hope it will help.

Power steering leak


To try to find the leak, purchase a spray can of engine cleaner and spray the entire area of the pump and hoses. Then wash off with a garden hose. Fill pump reservoir with fluid. Have someone turn the steering wheel while you look in that area of the pump and hoses with a flashlight for the leak. Be careful of rotating fan and belts!

I keep losing power steering fluid from resvoir and when the fluid gets low a loud widing sound accurs. What should I do?


You must have a leak somewhere. The whinning noise is coming from the pump. They make that noise when they are out of fluid.

Are you seeing any puddles or oil drops on the ground under your car?

A power steering resevoir is't very large so it won't take very long or a very big leak to run it out of fluid.

There aren't that many parts to a power steering system either.

The leak would most likely becoming from a hose, a connection or from the power steering component cylinder or box.

Leak under car (front driver's side)


What is the colour of the oil? Power steering oil will be red in colour or match it with the oil from powersteering oil reservoir. Its easy to locate powersteering pump. as it is driven by drive belts. So look around it and check for leaks. If no leaks, follow the hoses as far as you can and see if you can find leaks. You can also get underneath the car with a light and try to trace the leak.
