2000 Cadillac Seville front motor mount replacement

5 hours, what mount are you talking about? If it is the front engine mount it should be 1.1-1.2 hours. When we first started replacing them, warranty time was over three, but there have been several cuts in the flat rate time. The most recent of time guides should reflect the change. Basically, all you do is remove the lower splash shield. From there, remove the bolt that secures the brake lines to the frame, remove the mount to frame nut, and the two nuts and studs at the block(also the brace from block to trans), and then the upper two bolts. With the frame lowered in the front(a prybar can be used to pull it down as needed), the mount and bracket will rotate clockwise, and be pulled from vehicle bracket first.
