My power steering pump has always had seepage around the hose that connects to it, but recently I've began to notice small oil puddles on the floor. I'm tring to differentiate between knowing if it is actually power steering fluid or engine oil. I wiped some of it up with my finger and smelled it, and it has virtually no odor, and I think (correct me if I'm wrong) that engine oil has more of an odor to it? I have the GM V6 3.1L and the power steering pump is righ up top on the passenger side. Is this a fairly easy do it yourself job to replace one of these?
