Since some 1996 S-10s had different engine options (4-cylinder, V6), you'll need to:
1. Identify your engine: Look for an engine code (often stamped on a metal plate on the engine block) to determine the exact engine type (e.g., 2.2L 4-cylinder, 4.3L V6). This will significantly help pinpoint the coil pack's location.
2. Consult a repair manual or online diagrams: Once you know your engine type, use a repair manual specific to your S-10's year and engine or search online for images of the engine bay of a 1996 S-10 with your specific engine. Searching "1996 Chevy S-10 [engine code] engine bay diagram" will yield useful results.
Without knowing the engine, a precise location is impossible.
