Can the power steering fluid reservoir,in a 2006 Aveo, be replaced, without the fluid shooting out under high pressure? I am fairly sure one line has low/no pressure, with the car off. But is the thicker/bigger line under high pressure, even if the car is off? I don't want to take off the clamp from that hose, and get sprayed with fluid, or have it spray all over the engine/car.

So...does anyone know if either line is under pressure, if the car is off? My reservoir just looks old and black inside, the fluid is new and clean, but it looks black inside, so I want to replace it. Looks like a simple job, the part is cheap, and more fluid is cheap. This is my only issue I am worried about. Thanks.
