The EGR valve on a 2002 Chevy Silverado with a 5.3L V8 is typically located on the
passenger side of the engine,
near the back, towards the firewall. It's usually mounted on the intake manifold. However, its exact position can vary slightly depending on the specific engine configuration and any aftermarket modifications.
To be certain, you should consult a repair manual specific to your year and engine. A visual inspection with the engine bay cleaned is also recommended to help pinpoint its location. Look for a small, usually rectangular valve with vacuum lines connected to it.
