Changed engines on my 2007 Trailblazer LS 4x4 with a 4.2. Flushed the radiator when I had the engine out. The truck runs at 210 degrees. Is that normal? It doesn't over heat.

Normal.same as mine was, make sure no air left in the system.

Thank you MaxWedge! I changed the thermostat just for grins. It did not help. New thermostat is 192 degrees. Yet gauge reads 210. I'm not going to worry about it.

When you plug in the scan tool, and turn on the electro-viscous cooling fan, does the fan actually engage and sound like a tornado?
I was playing with that on my '03 4.2 last evening. Mine engages and dis-engages; even seems to partially-engage if I set the tool to less than 100% engagement. It takes a long time for the fan to kick in, though, and even longer to dis-engage.

I only have a small hand held scan tool.
No way to engage the fan. Thanks for posting.
