      Most water pumps in the Classic Prius make it farther than that, but
      100K miles is still a respectable life for a pump. If the pump is
      leaking, the coolant will be dripping out the "weep hole" (applies
      to all water pumps.) In the Classic Prius the water pump is expertly
      hidden under the intake hose of the air cleaner. The weep hole is
      probably on the bottom of the pump, where the crank pulley blocks
      the view from underneath. But if you could see it, a pink residue
      around the hole would betray the water pump as the culprit.

      I'm sure the coolant, like most coolant, is fluorescent. A look
      under the hood with a black light in darkened conditions should tell
      where the leak is. The pump and hoses are the main suspects.
