Because of the location and potential variations depending on the specific engine (2.0L, 2.4L, or 2.5L were common in '97 Sebrings), you'll need to consult a repair manual specific to your Sebring's year and engine to get a precise visual location. A picture or diagram in that manual will be invaluable.
Warning: Working on the starter motor involves working with the car's battery and potentially hot components. Disconnect the negative battery terminal before attempting any work to prevent accidental short circuits or injury.
