Where is the starter motor in an 02 Yukon?

In a 2002 GMC Yukon, the starter motor is located on the passenger side of the engine, toward the front. You'll likely need to access it from underneath the vehicle. It's typically bolted to the engine block near the bell housing (where the transmission connects to the engine). Precise placement can vary slightly depending on the engine (e.g., 4.8L, 5.3L, or 6.0L).
