Finally figured out a system. Problem is the 4 hex nuts that affix the fan to the hub. Need a 5 year old's hands to work in there. Here's my solution:

 

Tools needed:

Long hemostat. 10 inches, minimum

Long flat blade screwdriver. Same length.

Long 10mm open end wrench, cut and extended to a foot.

22mm open end wrench.

 

1. Place fan on hub. Cram a glove or something soft between the fan and radiator to hold it in place against the hub.

 

2. Using the hemostat, place the nut on the end of the stud and hold it in place with the flat blade screwdriver by pressing lightly on axis.

 

3. Remove hemostat and use either the hemostat or the long wrench to spin the nut onto the threads as far as it will go.

 

4. Repeat for the remaining 3 studs.

 

5. Put 22mm open end wrench on the fan shaft. It has a couple of flats, specifically for this task. Hold shaft in place while you use the modified long 10mm open end wrench to tighten all the hex nuts.

 

Done. No fiddling. Works like a charm.

what about just removing the radiator?

 

seems like less of hassle.Just catch all the coolant/water.

I don't think you can sneak the radiator in there with the fan on. Correct me if I'm wrong, though. cnc:-\

this is for EA82?if so I usually just bend the top portion of the radiator support out of the way just enough to slide the radiator out.Then bend back the support when your done.EA81 just slides right out the top
