I think it burped. I took it for a drive last night. It was about 70 degrees out, so cooler than other times I have tested it. However, I was able to make it up the pass I was trying to do before. The temps held at about 208 as long as I kept the speed up to 35-40mph. When I stopped a few times and started up again, the temps would climb to 217 and then slowly come back down to around 208. I find these temps for a mountain climb to be acceptable, but I still have reservations since it was dark and 70 degrees out instead of sunny and 100. It should be sunny and 85 degrees today, so I'll try it again and see if I get similar results.
