Where is the EGR valve located on a 2001 Chevrolet Camaro Z28?

On a 2001 Chevrolet Camaro Z28 with the LS1 engine, the EGR valve is typically located on the passenger side of the engine, near the back. It's usually mounted on the intake manifold. It's a relatively small valve, often with a vacuum line connected to it.

However, precise location can vary slightly depending on specific manufacturing variations. The best way to be sure is to consult a repair manual specific to your vehicle's year and engine (LS1). A diagram in the manual will clearly show its location. You can also use online resources like repair manuals available through websites like Chilton or Haynes.
