Default feels like manual steering but has ps pump

Hi I just bought my mustang. I noticed the steering felt a little heavy but not too much. It doesnt make any whining noises and at low speeds its hard to steer and park. But I checked and saw the ps pump on the belt. And it had green fluid in it. Whats uo with that?

The fluid is either very very old, or someone put a synthetic fluid in it. There are a few brands of synthetic fluid for import cars that is green.

Do you have under drive pulleys? Those will make the steering seem heavy at idle speeds.

I can't say for certain that the fox mustang had this, I simply don't remember, but a pressure sensor in the steering lines is responsible for bumping the idle a tiny bit while not moving so that you don't experience what you just said.
