Maybe. And we don't know that the OP's trip isn't to Death Valley in September :-)

Nor are all cars designed to handle quite that much, at least judging from seeing various overheated vehicles by the roadsides of the local mountains (which are somewhat cooler than Death Valley). I wouldn't recommend a grille block in summer temps/mountains unless you have a ScanGauge or similar that will tell you the exact coolant temperature. I've certainly seen my Insight's coolant temp (with the block removed for summer) go up into the 220F range when climbing stiff grades on a hot day.
