ABSTRACT:
The invention makes use of a second thermostat in an engine cooling system, normally equipped with only a single thermostat. The second thermostat differs from the single thermostat in that provision is made for a constant, though materially diminished, flow of coolant past the second thermostat which, when the need arises, is converted to full flow by action of the second thermostat.
