[MR2] Cold weather, cooling fan light, and coolant loss

Does the person who did the coolant change know how to bleed the system? How did they find it a quart low? How far did you drive the car to get the oil change?

Subject: [MR2] Cold weather, cooling fan light, and coolant loss
Took my 86 MkI in for an oil change, and it had lost about a quart of
coolant (it had been flushed and filled in the fall). A couple of
miles after driving away, the red cooling fan light came on. No other
changes -- temp was slightly on the cool side as it has been for 25
years, voltage same as it usually is, and hot air came out of the
defroster and heat vents. Stayed like that til I got home ten miles
My experience has been that the red cooling fan light is one of
several that come on when the alternator is feeling tired. But I
don't remember it ever coming on by itself.
The only unusual thing I can think of is that I hadn't driven it for
about two weeks, and it has been sitting outside in freezing weather
-- the overnight low has been anywhere from 20F to 28F, and only a
couple of days have had highs over freezing. Very little snow, an
inch or two a couple of times, six inches once. I had to yank a bit
to get the door open, the engine started up after a couple of seconds,
and I let it warm up while I scraped all the windows. There was ice
on the inside of the windshield and moon roof. It started melting
when I was about 5 miles from home, halfway to the garage, dripping on
my head, but there were no other wonky lights. Maybe water got inside
the dash somehow and picked on the coolant light?
Assuming the fall coolant change wasn't just water, is there any
likely link between this freezing weather, the missing quart of
coolant, and the red light?
