OK! Here is what you are going to have to do about your car.power steering problem. How do i know?? Trust me, my 1999 SC300 did the same thing last week. Remove the power steering pump from the car. Remove the PS resevoir and drain it of the old fluids. Then look very closely into the resevoir and look to see if there is what appears to be a small piece of screen in the bottom of it. this screen is attached to the inside of the resevoir to filter out any larger pieces of debris that may be introduced into the system. If you will notice, with the help of good flashlight ,check at the bottom of the resevoir you will see the pump feed hole. This screen/filter has been detached from it's mounting and has been sucked down into the pump feed hole. Remove the screen section that has broken loose and trash it. This screen is stopping up pump feed causing your power steering problems. Good luck bud!! Hope this helps out

Did you check the fuelid level today? A loud whine indicates low fluid or a defective pump in most cases.

Steering pump needs fluid once a week. Doesn't seem to be leaking to the ground but it is whining loud and low sound like it is out of fluid even after I fill it.


your power steering pump is going bad the bearings inside are worn out and thats what causes the whining sounds that change when you turn the steering wheel your going to have to replace it.

replace the power steering pump. make sure you get crush rings for the hoses too. dont use stop leak stuff either because it WILL clog the filter in the power steering rack and then youll have to replace that too.

Leaking Coolant / Broken Pulleys /etc


Pressure test the system and check for leaks, use a radiator pressure testing tool kit. Sounds like the radiator may have been damaged by the parts breaking and flying about.
