In order to quickly bring the temperature of both the engine and the engine lubricant up to desired operational temperatures and subsequently prevent overheating of the same, an oil cooler is integrated with an evaporative type engine cooling system in a manner that the temperature of the engine oil is controlled essentially in parallel with engine coolant. The engine load and/or engine speed are sampled and the cooling system operated in a manner to vary the boiling point of the coolant in accordance therewith.
