Split Cooling Method and Apparatus

A cooling system for an internal combustion engine, comprising:

• an engine cooling loop, comprising:
• an engine;
• a control valve;
• at least one engine coolant radiator;
• an engine coolant expansion tank;
• and
• an engine coolant pump.
• an intercooler loop, comprising:
• an intercooler for receiving combustion air from a turbocharger, the intercooler comprising an air-to-liquid heat exchanger for exchanging heat between the combustion air and a liquid coolant;
• a first intercooler radiator comprising a heat exchanger for exchanging heat between the liquid coolant and ambient air;
• an intercooler pump;
• and an intercooler loop expansion tank.

A cooling system for an internal combustion engine comprising:

• an engine;
• an intercooler for receiving combustion air from a turbocharger, the intercooler comprising an air-to-liquid heat exchanger for exchanging heat between the combustion air and a liquid coolant;
• an intercooler radiator comprising:
• a heat exchanger for exchanging heat between the liquid coolant and ambient air and
• a fan;
• at least one engine coolant radiator;
• an expansion tank;
• an oil cooler;
• and
• at least one pump,
• wherein the fan is controlled by a temperature switch or a microprocessor controller,
• wherein the temperature switch comprises a temperature sensor which detects a temperature of the liquid coolant,
• wherein the temperature switch or controller energizes the fan when the temperature of the liquid coolant is within a specified range of temperatures,
• wherein the temperature switch or controller de-energizes the fan when the temperature of the liquid coolant is within a specified range of temperatures.
