Finding the right replacement depends on whether you need the unit itself or just the sensor. The sending unit is usually located on the engine block, near the oil filter. However, the *exact* location might vary slightly depending on the specific configuration of your engine and other components.
To find the correct replacement part, you need:
* Your vehicle's VIN (Vehicle Identification Number): This is the most accurate way to ensure you get the correct part. Use this number with a parts website (like AutoZone, Advance Auto Parts, Napa Auto Parts, etc.) or your local parts store.
* The engine code: This is usually found on a sticker on the engine itself, often near the valve cover. While it's a 6.0L Vortec, there might be subtle differences.
Without this information, providing a specific part number is impossible. The parts store's website or a parts professional will be able to use your VIN or engine code to find the exact match.
