Where are the Knock sensors on chev 2001 6.0l engine?

On a 2001 Chevrolet 6.0L engine (likely an LQ4 or LQ9), the knock sensors are typically located on the engine block, one on each side of the engine. They're usually near the cylinder heads, but their exact placement can vary slightly depending on the specific engine configuration.

To be certain, you should:

* Consult a repair manual specific to your year and engine code: A Haynes or Chilton manual, or a factory service manual, will have diagrams showing the exact location.

* Use a reliable online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, model, and engine, and then view a parts diagram showing the sensor locations.

Without a specific visual reference for your engine, providing more precise directions is difficult and could lead to misidentification of other components. Always use a reliable resource to locate components before attempting repairs.
