Does anyone have a work guide for A 2001 Cadillac Deville. My Dilemma is that I need these replaced, but my warranty is telling the dealership that this should only take 1.5 hours but the Dealer is saying that it should take 3.5 hours and they won't pay for the labor and the warrany is asking if they can fax in a page from that says this job takes 3.5 hours they will pay...But the dealer get's their info from the computer and the mechanic explained to them the work involved. So any help would be appreciated. By the way the job cost's about $440 and i'm getting it done regardless because the car idle is awful.....Thanks everyone.
