Where is the egr valve located on a 1999 Chevy Express with vortec v6 engine?

The EGR valve on a 1999 Chevy Express van with the Vortec V6 engine is typically located on the intake manifold. It's usually on the passenger side (right side when sitting in the driver's seat), near the back of the engine. However, the exact location can vary slightly depending on the specific configuration of the intake manifold.

To be certain, you should:

* Consult a repair manual: A Haynes or Chilton manual specific to your year and model will have a diagram showing the precise location.

* Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle and view diagrams of its components.

* Search online for pictures: Searching for "1999 Chevy Express Vortec V6 EGR valve location" on Google Images might yield helpful pictures.

Remember, working on your engine can be dangerous. If you're not comfortable doing it yourself, it's best to take your van to a qualified mechanic.
