  Neither presumption is warranted.  When the radiator is replaced,
  air bubbles in the engine can happen and are a pig to get rid of.
  As for the water pump, if it can only pump enough water at high
  rpm, you'd get cold air at low speed.

  Actually, I wonder if they installed the wrong water pump, and
  the impeller is being spun backwards.  Since it is just centrifugal,
  I could be convinced that it might actually push a *little* water
  at high rpm when run backwards...

  Nothing other than a water pump flow test is good enough to prove
  or disprove that it is the cause.
