The manual just says loosed the four screws, disconnect electrical, remove.
But I had to take the upper hose off, which required draining coolant, etc.
I'm stumped. The small saw comes out next to slice the shroud, and epoxy
later.
Anybody able to tell me what I'm missing, considering the manual made it
sound REAL simple, and tech time is shown as 0.9 hours.
Thanks in advance!

This was so much more than the manual said. I had to remove the bracket
screws, of course. Then remove upper radiator hose. Here's the rest- loosen
the three schools that hold te motor to the bracket. REmove the screws that
hold the a/c accumulator to teh shroud, and the remainder of the shroud
upper screws. Now, after backing teh motor mounting screws (3 of 'em) out
about 3/16", pry the power connector off the motor, and then pull the shroud
top back, it will move about 1" or a bit more. Snake in a 1/2" socket wrench
onto the nut that holds the fan blade assembly on. BAck it off. And then
work the fan blade off the motor, and then carefully back out the three
motor mounting screws. Carefully remove the fan mount bracket, and the
motor, eventually get the fan blade out.
Here's the rest of the story re: installation:
First, out of the car assemble everything to make sure it all fits. The
Siemens motor I bought needed a washer, not much of one, under the nut that
holds the fan blade assembly to the motor.
Remove the fan, place it inside the shroud ahead of putting the
motor/bracket in. next, put the three screws in that hold the motor to the
bracket, but only enough thread in to not let them fall out.
Put the bracket/motor in place, will need to jack around with refrigerant
hoses, etc.
Once in place (need skinny hands/arms here) tighten the screws that hold the
motor to the bracket. And remember, you have removed the top row of screws
for the shroud.
Pull back on the shroud top, and place the fan blade assembly on to the
motor shaft. It is keyed with several plastic "nubbies" inside the hub.
Remember that.
Next, I used a box wrench to set the nut on the shaft. It is reverse
threaded, so be sure you turn the right way, or you'll be there forever
backing it off. I held the nut with the wrench, and simply spun the fan
blades to tighten, the last bit just had to do that tightening manual type.
At this point, just re-mount all the crap you removed in the process. Don't
forget the electrical connector.
Done.
I hope I saved someone some time. I spent way too much time trying to figure
how the manual's method could be accomplished. It can't. Period.
I hope my secondary one hangs in. I really hate moving a/c components.
System is tight, moving stuff can only disturb that status.
Local Chevy dealer told me the manual was written by some engineer who
didn't know how to use a wrench. :o)
Said they have found the easiest way to do this is to pull the radiator/AC
condenser/Fan assembly cartridge. It is a LOT more expensive because it
means a new drier for the A/C system, pumping the system down, new
refrigerant (and if the conversion hasn't been made to R134 yet, it is
REALLY a lot more).
The posts here prove again why this forum is valuable. The Chevy dealer
here told me the cost to swap out the fan motor would be AT LEAST $600.00.
I can nurse a couple of busted knuckles for that much money, plus it gives
me and excuse to tinker on my toy and enjoy a few carbonated beverages in
the process.
