Power Steering Fluid Leak

The pink/red fluid leaking from the front of your 2003 Cadillac DeVille could be transmission fluid; coming from the transmission cooler connections at the radiator, the cooler lines, or the transmission itself. I am surprised to hear that your first leak of pink/red fluid was from the power steering system. GM has used a clear fluid for the power steering since at least way back in the early 90's
