Honor your engine cooling temps by slowing down and turning off the airconditioner if necessary. The big rigs get down to really modest speeds on the climbs so be prepared to either get in line or pass briskly and not hold up the Formula 1 drivers (in their own mind at least) that consider the posted speed limit as only useful information for the police officer filling out the speeding ticket.
Avoiding the weekend racers is good advice. Lots of white crosses along I-17 are not visible, but should be there. Countless Darwin awards made on that stretch of highway.
