UH, typically running hot on the highway is a sign of a stuck thermostat- regardless of what they told you. Check the fluid level though. Sometimes these new systems are harder to fill than you think, so make sure you have enough coolant in there. Make sure you put the right kind of coolant in there if you add some. You'll have either gold or red, unless they cheaped you out with green. Whatever it is, it's never right to use Dexcool, and match the color if you have to add some.
