What are you considering hot? 210 degrees for short stints is pretty normal usually once cresting the grade they will cool off settle back in around 180-190.
While absolutely true, I would suggest that once coolant temperature rises above thermostatic control (fan on high speed on side radiator systems) one needs to start addressing the condition.
That likely means lower gear, higher engine RPM and backing out of the throttle. Using this technique,we have successfully climbed long 6+% grades in 100 degree weather without coolant temperature rising more than 10-12 degrees F from thermostatic control. And, passed other DP's on the side of the road with severe overheating under exactly the same conditions.
