I'm sure we have different engines
But this is what I have
a) Single main fan inside the engine that is sitting on the fan clutch * not electrical fan
b) Two aux fans sitting in front of the radiator (electrical)
Only one aux fan has motor (that went bad), the second aux fan is rotated by the first one via small belt
I had to order only a single aux fan with motor.
We did not have to remove the radiator, as far as I remember we only pulled the console with 2 front fans out, replaced the fan with the motor and placed everything back (1 hour procedure). I think that fan was couple of hundred $$
