Where is the egr valve on a 2004 Pontiac Grand Am?

The EGR valve on a 2004 Pontiac Grand Am (assuming a 2.2L or 3.4L engine) is generally located on the intake manifold, near the back of the engine. It's often a small, rectangular or cylindrical component with a vacuum line connected to it.

However, precise location varies slightly depending on the specific engine (2.2L or 3.4L) and even minor variations within those engine types. To be certain, you'll need to:

1. Consult your owner's manual: This is the most reliable source, as it contains diagrams specific to your vehicle's model.

2. Use a repair manual: A Haynes or Chilton repair manual for your specific year and engine will have detailed diagrams and instructions.

3. Use an online parts diagram: Websites selling auto parts (like AutoZone, Advance Auto Parts, etc.) often have online diagrams that you can search by your vehicle's year, make, model, and engine size. These will show the EGR valve location visually.

Without knowing your exact engine type, a precise location can't be given. Always visually inspect and confirm before attempting any work.
