No, you do not have to remove the engine to replace the timing belt on a 2005 Chrysler Sebring with a 2.7L engine. While it's a somewhat involved job requiring significant access to the timing components, it's doable without engine removal. You will need to remove various components to gain access, including some ancillary belts, pulleys, and potentially other parts depending on the exact approach taken.
