You make that sound easy. By the time I finished mine I was almost in tears from frustration (and hitting my knuckles trying to put that d=-=- fan back on).
That having been said, it can be done even by a novice like me. I would definitely go by an auto parts store and pick up a Haynes or Chilton's book and plan on working for a few hours.
Oh yeah, mine is an XJ which would account for the cramped space and knuckle banging...it might be easier with another model.
