Hello and welcome to Just Answer!
The first thing you need to do is disconnect the battery!
-Remove the plastic belt splash shield from under the van.
-Remove the serpentine belt by putting an open end wrench on the belt tensioner lug and rotating the belt tensioner counter clockwise so the belt can be removed from the alternator. There is no need to remove the belt completely, just take it off the alternator!
-Remove the 3 alternator mounting bolts and move the alternator out of the way so you can easily access the EGR bolts.
-Remove the 2 EGR bolts that hold the EGR to the cyl head and remove the 2 tube bolts and remove the valve.
To install just reverse this procedure!
It would be a good idea to have a helper around to remove and install the belt!
I hope this helps!
I totally understand! Let me know if these don't come through! These are the only pictures I can find and I hope it helps you! The top image is a picture of moving the alternator, the second image is the belt tensioner, the third image is the EGR valve and tube, the fourth is the EGR valve gasket and the last image is the belt shield!
