To be more precise: You'll want to look on the back of the intake manifold, near where the exhaust manifold meets the intake. It's often close to the firewall. A repair manual specific to your 2001 Dodge Intrepid 3.5L would be extremely helpful in locating it precisely, as well as showing you the removal procedure.
Caution: The engine will be hot if recently run. Allow it to cool completely before attempting to access or work on the EGR valve.
