    Did one a couple of weeks ago on my 318. Take the fan assy off the water pump then just unbolt the clutch from the fan, reassemble with the new bolts provided. Not a badd job at all.

    Those are pretty easy. Try to change a radiator in one without taking the fan out. What a pain.

    I changed the water pump in my Dakota 318. I had an awful time trying to get the fan off. No one had the tool to remove that thing. I recommend that you find that tool. The tool holds the water pump so you can unscrew the fan off of the water pump.

    According to the factory 1993 service manual:
    the thermal Viscous Fan drive (clutch) is attached (threaded) to the water pump hub shaft. (right hand threads!) Remove the viscous clutch/fan assembly from the water pump by turning the mounting nut counterclockwise as viewed from the front. a Snap-on 36MM Fan wrench (number sp346 from Snapon Cummins Diesel Tool Set 2017DSP) can be used. Place a baror screwdriver between the water pump pulley bolts to prevent pulley from rotating.

    Also it says after removing the viscous clutch/fan assembly DO NOT place the clutch in a horizontal position- if stored that way the silicone fluid in the clutch could drain into it's bearing assemblies and contaminate that lubricant.

    I don;t think you need any special tools- just a 36 MM wrench.

    Easiest way to do it is get yourself a 12 inch adjustable wrench, put it on and whack it with a hammer. It might take a few hits but it will come loose.
