1. Identify your Impala's year and engine: This information is usually found on your vehicle's registration or the sticker inside the driver's side door jamb.
2. Consult your owner's manual: The owner's manual will have a diagram showing the location of the oil filter and other important components.
3. Use an online resource: Search online for "[your Impala's year and engine] oil filter location" Many websites, including repair manuals, forums, and YouTube videos, show the location visually.
Without knowing the specific year and engine, I cannot give you a precise location.
