Where is egr valve located on a 2000 Chevy Express van?

The EGR valve on a 2000 Chevy Express van is typically located on the intake manifold, near the back of the engine. However, the exact location can vary slightly depending on the engine size (4.3L, 5.7L, or 6.0L). You'll find it connected to both the exhaust manifold (via an EGR tube) and the intake manifold.

To be sure, I strongly recommend checking a repair manual specific to your van's year, make, model, and engine size. A diagram in that manual will show you the precise location. You can usually find these manuals online or at auto parts stores.

Looking at pictures online of 2000 Chevy Express engines with your specific engine size will also help you pinpoint it. Be aware that access might require removing some components for better visibility.
