Where and how do I go about changing the egr valve on a 1997 Caravan with a 3.3L engine?

Where and how do I go about changing the egr valve on a 1997 Caravan with a 3.3L engine?

According to the factory service manual, the EGR valve and Electrical EGR tranducer are serviced as an assembly. The egr valve bolts onto the intake manifold. I was unable to find it on my engine, and the book photos aren't much help. If you find it please post back, thanks.

It should be right under egr solenoid left rear engine.
As posted before it comes as a assembley .
Solenoid and egr valve together.
Dealer idea or aftermarket has picked up on it to.
Why are you replacing it or looking for it?
