How to change plugs in a 3.8 L

OK, I thought maybe I would change the spark plugs in my 2002 Dodge Caravan, 3.8L. The front looks pretty easy, but wait... How in the heck do you get to the back 3 spark plugs? Do you have to go from the bottom of the van or what? Anyone have any tricks for this? I have 65000 miles on the van.

You can remove the wiper module and it gives you great access to the back of the engine. I strongly recommend doing it this way since it only takes about 15 minutes to remove and will save a lot of trouble trying to do it by feel. That said, it is possible to reach around the engine and do it by feel-- I've done that too, but it wasn't fun.

Check the maintainance schedule as I know that at some point on the 4th Generation vans (2001-2007) they went with platinum plugs that should last 100,000 miles. Is the van running smoothly?

I didn't remove the wiper module but was able to change the rears from above strictly by feel. It really wasn't that bad at all. I changed ours at about 80,000 miles and quite unlike my Bonneville who's plugs were toast at 60,000 miles, these looked virtually brand new.
