Just curious, as it only happens to me when the a/c is on. It can be 110 degrees, sitting in traffic, and if the a/c is *off*, everything is okay. However, 90s, a/c *on*, the fun begins. I'm curious as to who has a VX that overheats *without* the a/c coming on?

Is it possible that the issue is an A/C issue, and *not* a coolant issue?

Another thing.....the corresponding model year Troopers don't overheat, and they share the same drive train.
