Mine gets to almost 220 every day after sitting in traffic AND a steep hill to climb when I get home, sitting in stop and go in this heat gets to 213-215 easy, with this VX and my other VX, same scangauge. And the stock temp gauge moves ALOT when the scan gauge moves only a tad, so when it looks like it is very near overheating the difference in temp is really only like 10degrees.
Yep-yep...I've seen 218+ in stop & go traffic on the trails around Moab...
Your rad should have a volcanic steam eruption, causing you to switch off the ign key, before it spits out a head gasket.
