I have an '03 and it has the electric fan, which is in the way to access the oil filter from the top of the engine bay. The crossmember and other stuff is in the way from below (for me). I ended up lifting the front on a hydrolic jack and squeezing my arm through the very narrow opening to access the oil filter. I've changed the oil to a variety of vehicles over many, many years, and this was by far the most difficult for me to reach. Getting a filter wrench in there to get it loose was hard for me. It was serviced by a garage the last time, and whoever tightened that old filter really cranked it on.
Now that I have the experience, I assume that it'll be easier for me the next time. Plus, I only tightened the oil filter hand-tight like I do all my vehicles; it makes it easier to remove!
I inherited this Jeep from my father-in-law after he died last summer; I've owned it since October. I'm overall happy with it, but it has a few quirks that take getting used to (like an oil/filter change). It does consume more gas than any vehicle that I've owned, but I do like the rumble under my seat from the 3.7 L, 6-cylinder engine. :driver:
