[V8] Engine Runs a Little Hot

I don't know the logic for the fan control; assume it uses a resistor
pack to vary speeds?
I assume the electric cooling fan should run low speed whenever the car
is on, with the climate control in any mode using the compressor (older
cars that's not OFF or ECON, newer style with A/C snowflake)????
After replacing the fuse, make sure the fan comes on when it should.
Probably should find the radiator mounted switch and jumper it to make
sure the higher speeds come on.

At the front of the hydraulics system reservoir there's a small black
If you open the lid on the box, you'll see what's called a fusible link
running between two screws. You want to BE SURE that link is intact.
Don't just look. Either test with a meter or take out one of the screws
to be certain the strip is in one piece. They're usually under a dollar
from the stealer. It's an 80-amp fuse. Or you could replace it with
one of those holders that hold a blade-type fuse and get an 80-amp fuse
The fusible links tend to deteriorate with age.
