Alright, I know this isn't the best place for this but any and all help is appreciated. its an 05 aveo (girlfriends car) and about three months ago the steering pump went out. So I replaced it and now, for the third or fourth time, the return hose for the fluid was blown off the fluid reservoir. I have emptied, refilled, and bled the system several times and it still blows off eventually and has had a constant whirring noise since the first time it happened. Is this a pump problem or could it be something else? It's been fine for about a month until this past weekend. I'm not having any luck finding straight answers. Thanks.
