High: 46.4 ?F / 8.0 ?C
Low: 12.0 ?F / -11.1 ?C

and

Now: 15.8 ?F / -9.0 ?C

It was so cold the exhaust fumes were fogging the rear window for all my
driving. (Wagon aerodynamics...that's why wagons/hatchbacks have rear
wipers)

Sent this premature...could this be problematic with CO getting in the car?

Do you drive with the hatch open?

If so, the manual says to run the fans full blast..

Not unless something's being hauled, didn't see that spot in the manual
but it makes sense to try and push as much air from the front as possible.

That's warm...

This Sunday it was -24?C, -37?C with the wind chill... Monday was
about -20?ish (again with wind chill) i'd say... went up to -13? during the
heat of the day... My commuter car is a TDI diesel, even w/block heater
plugged in had a 15 second glow from the plugs, and I never got real cabin
heat (heat that wouldn't go to icy coldness when I came to a stop) for
nearly 20kms.... I'm sure the Volvo did well that day - but yes, it blows
whitish coloured exhaust past the rear window on cold days too.... The
exhaust seems to get pulled upwards into the draft coming off the car, this
draft spirals air at the back of flat-backed cars... my TDI Golf has the
same problem...

It's perfectly normal that in cold weather you can see your exhaust, but
at -9? you shouldn't see anything after the car warms up... and at +8? I
wouldn't expect anything at all to be visible.

BTW I live in Southern Ontario, and these temperatures were really cold for
this time of year, even in late January it isn't usually quite that cold.

Rear windows fog up in the cold for other reasons... you should have used
the rear defroster... Just from your body heat and inertia I suppose all the
heat must fly to the rear window and condensate on the outside of the
glass... The rear defroster is a switch to the right of the steering wheel
(near the sunroof switch) on a 960, and I believe the 850's and 760's were
the same location... you didn't mention the car.

It's an 850 and I did have the defrost switch on but this condensation
was most definitely on the outside of the car.

I'm due for a 120k tune-up so perhaps it's just not burning the fuel as
well as it should in the cold. Doesn't this engine also run pretty rich
when first started, thought I read that somewhere.

We'll see how it does with new cap, rotor, plugs and all that.

Well water vapor is one of the main byproducts of combustion so this could
be perfectly normal, might just need some wax or something on the rear
window, dish detergent works well too (liquid) but probably won't last long
outside.

A wonderful offer but I'll pass even though I'm suffering here in Seattle 51
day and 42 night :-) Merry Merry to all!

Pfff. -11 degC is warm.

It was minus 35 degC with windchill here the other day (only about
minus 20 or so without the wind chill) and it was refreshingly brisk.
My ancient 245 didn't have any trouble starting.

That day, a friend in Manitoba whose home if off of the power grid told
me:

"It was -40 here this morning exclusive of windchill.
And the regulator on the propane tank was frozen again, so the fridge
was shut down, but that didn't matter much given that it was 13 degrees
in our house, and the PV
controller freaked out when the sun hit the solar array and the
open-circuit voltage exceeded 145V due to the cold."

He also mentioned that later in the winter when it gets colder, it'll
get down to minus 50 degC.
