There was a similar item sold through the late 1980's (prior to the advent of FI) where the radiator temps would spike on hill-climbs for tow vehicles [RV's]. Severe heat spike. It used a windshield washer pump, that reservoir made common (and/or enlarged) and distilled water recommended (for reasons above: corrosion and mineral build). IIRC it was four spray heads mounted so as to cover the entirety of the first heat exchanger (generally the A/C condenser).

By report this worked best -- the temporary increase in surface area -- in dry, hot, higher altitude climbs.
