Hey there, flatlanders!
My daily commute tops out at 7343' elevation at the end of a medium length steep grade at 75mph speed limit. Furthermore, I can be at 14,110' (the top of Pikes Peak) within an hour of leaving my house (or less, depending on traffic and road conditions). At my house (6300') water boils at 201*, which means I have less coolant temperature margin than most.
Even if you don't live and drive in high elevation, you may want to vacation here sometime, and you have to plan for the extremes. So it seems to me that a 205* t-stat would risk coolant boil at high elevations unless you were using waterless Evans. Any thoughts?
If I did ever convert to Evans, a quick trip up Pikes Peak with a loose radiator cap seems like a fast way to purge leftover water. Water boils at 186* at the top.
I just picked up a Stant Superstat 45379 like GreenENG has (p36, post #528). Even though that's a 195* t-stat, he reports running at 205*. When I get it installed, I'll post my results back here for comparison. When I left to get it, I hadn't seen GreenENG's post yet -- otherwise, I might have just gotten the regular Stant because of my high-elevation concerns. BTW, the regular Stant would have been $8, the SuperStat was $10. According to the Stant website, the Superstat regulates temp more evenly with fewer and narrower temp swings compared to a regular t-stat.
