The STAR hotline won't be much help, I assume. And, if the Crossfire is like other Mercedes-built cars that I know of, you are probably stuck with a difficult and incomplete shop manual on a CD instead of Chrysler's usual excellent bound paper manuals. I would suggest checking with a Mercedes dealership in town, or following up with Mercedes' tech line. The 3.2L is used in a lot of MB cars. I'm sure the guys in the MB dealership have taken at least one apart before.
