Pick up an inexpensive tester and check it afterward. I haven't seen one at the store in ages, but they used to be about $1.00 by the register.

The new sensor/sending unit is installed, problem solved!  She heats right up to the bottom of the green zone and stays there nice and happily.

I also checked the freeze point of the coolant.  Basically I had the whole system flushed out with distilled water, and drained what I could out of it.  Per the chart on the peak antifreeze bottle I added 6 quarts of straight coolant and filled it the rest of the way with distilled water, which is supposed to achieve a freeze point of -34 in a 14 quart cooling system.  After driving it around to get the coolant mixed evenly, I took a sample with my digital antifreeze refractometer and came up with -33 so I came pretty darn close to my target!
