where do i put the power steering fluid at, in a 2001 buick regal

"The power steering fluid reservoir is located at the back of the engine compartment on the passenger's side of the vehicle, near the engine coolant recovery tank. See “Engine Compartment Overview” in the Index for more information on location." This is right out of the owners manual, it even shows a picture of the cap. It says right on it "POWER STEERING Do Not Overfill Use Only Approved Fluid". But you would also need to look in the manual for the approved fluid. You don't have a manual you say? No Problem. You can download one FREE here: http://www.autousermanual.com/view/buick/regal/

Easiest to access from under the car with car on hoist or ramps.
