-2 last night.

For anyone who might be in a similar situation, I was able to complete
this task during my lunch hour without climbing underneath, and without
even getting dirty.

I bought a small handheld transfer pump for $14 at Advance Auto. I
carefully fed the top/suction side down into the radiator about 18-24",
and pumped out 2 gallons into some empty antifreeze jugs. I then
refilled it with about 1.75 gallons until it reached the top, and poured
the remainder into the overflow to be sucked in later after the air
worked its way back out. This pumping/refill process was only about 5
minutes total.

I started her up (with a little help from some starter fluid) and ran
the engine for about 15 minutes to thoroughly swoosh the new fluid
around.

Not sure what the protection level is now, as the cap was warm and I
didn't want to open it to check, but certainly better than the +10.

Thanks to all for the reminder to check the antifreeze protection!

Our coach had been fairly well drained when we first bought it, and we
had filled it at the time with a couple of gallons of distilled water
and a couple of gallons of pure Prestone, but I remembered checking with
the tester and seeing it wasn't optimal. Went back today to check and
it tested to +10 degrees protection.

Now I'm not sure how accurate that tester is, as it had dipped to around
3 last night, and it was 9 when I tested today and it was still liquid
with no signs of ice crystals.

It's supposed to warm up to a balmy 20 degrees tomorrow, so I plan to
siphon a gallon of mix out of the radiator and replace with a gallon of
pure Prestone, then run the engine for 10 minutes or so to stir it all
up.

It's supposed to be -10 on Saturday, so better safe than sorry!
