I have a few friends named Haynes and Chilton who know--along with a million other things :P

Seriously, though, you should really pick up a Haynes or Chilton manual at your local Auto parts store. It will pay for itself in absolutely no time at all, and it isn't even expensive anyway.

I myself know nothing about replacing it, but i'm sure alot of the other members do and will reply soon. Good luck.

This is a pretty easy job. You will need to take off the serpentine belt. and probably both the auxilarry fan and the main fan.Drain some of the coolant out. Unscrew the bolts holding on the water pump. Scrape the old gasket material off. put new gasket and water pump on. Torque the bolts. Replace the fans and serpentine belt. Put back in the coolant. If 87-90 burp the cooling system. You might think about replacing the thermostat and the coolant at this time. I'd get a Haynes or Chiltons to follow direction.

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.

Actually, the Jeep is pretty easy to work on comparatively. Usually the scraped knuckles come from bolts that have been assembled for a while. They somewhat corrode together and are harder to loosen. The clutch fan presents problems for some, as it spins when you try to loosen the bolts. I use a long screw driver and put it between two of the bolts to stop the rotation. THen loosen on of the other bolts. I keep all the bolts in there till I loosen all of them.
Believe me, the 4.0 in at least the Cherokee and Comanche have some room around the parts as compared to a lot if not most cars. Pop the hood on a newer Honda. I don't even see how air flows around those engines.
