I am female who knows a liitle about cars.I'm pretty sure it's not over filled. But it has pressure on the cap when you open it and that's not suppose to be.The steering is find. I know that when I bought the car used of course, i saw that it had that problem when they aquired the car and i think they change the power steering pump and the belt. I reseached rack and pinion and power steering and the hoses. what do you think?
