About Nissan Oil Cooler

The reason of exist of oil cooler is in order to maintain the lubricative properties of oil, and the oil has to be cooled down in a proper temperature range. The engine oil works not only in lubrication, but also in cooling since the oil carries away a lot of the heat produced by the engine.
