However, the exact location can vary slightly depending on specific engine variations or modifications. It's best to consult a repair manual specific to your 1997 Saturn SC2 with the SC2 engine (often referred to as a 1.9L Ecotec) for a precise diagram. A visual inspection, once you're comfortable working around the engine bay, is also recommended. Remember to turn off the engine and allow it to cool completely before attempting any inspection or repair.
