2006 3.7 Overheat
On my way back from LA to phoenix and I had an immediate overheating issue. Took about 10 sec to red line. Cooled it down, changed t-stat, serp belt, water pump, and did a radiator flush. I have slightly higher than normal operating temp at idle and city traffic. I still overheat at highway conditions, but I can keep reasonable temps over long periods venting through the ac.

Side note. On the way to LA, we got an electrical issue. dash lights dim automatically, the roof light will flicker on and off, and my right headlight won't operate unless the brights are on.
