To be sure, you'll need to consult a repair manual specific to your vehicle's engine (2.5L or 2.8L). A diagram in the repair manual will show the precise location. Online resources like auto parts store websites (e.g., AutoZone, Advance Auto Parts) often have diagrams for specific years and models that can help too. Searching for "[Your Engine Size] Chevrolet Celebrity EGR Valve Location" should yield good results.
