To be more precise, you'll find it on the driver's side (left side, from the perspective of sitting in the driver's seat) of the oil pan. However, the exact location on the pan might vary slightly depending on the specific engine (4.3L, 4.8L, 5.3L, 6.0L, etc.).
It's crucial to consult your owner's manual for a diagram and specific instructions. The manual will show you the exact location and provide important safety information before attempting an oil change. Trying to locate it without a visual aid or familiarity with vehicle mechanics could lead to difficulty.
