    If it ever fails to run at 210, then your thermostat is prob stuck open. It's a fairly common problem that even happened to my mom's Trailblazer. Trailvoy.com has loads of great info on those suv's.

    Mine is exactly the same. I thought 210 might be a bit hot but I guess it's normal. The one thing I do like is I get heat fairly quick on cold days!
