I have a 96 4.0. I found the egr valve under the hood, near the battery. It has a small pipe that connects to the exhaust pipe, and is bolted to the drivers side of the engine. It also has vacuum line attached and is either connected with a hose or is ported to the intake manifold. It's been a while since I've messed with it. Mine was not frozen, so I didn't replace it. Of course I'm still getting a trouble code p0401. I now suspect a vacuum leak that prevents the valve from opening properly. I still need to check that out. Good luck.
