Cummins Engine Parts Oil Cooler Core 3974815/3918175 For Cummins 6C8.3 Engine

Product Description

The oil cooler is a device that accelerates the heat dissipation of the lubricating oil to keep it at a lower temperature. In the enhanced engine with high performance and high power, the oil cooler must be installed due to the large heat load. The oil cooler is arranged in the lubricating oil circuit, and its working principle is the same as that of the radiator.

There are two types of oil coolers: air-cooled and water-cooled. And this product 3974815 is water-cooled oil cooler.

Water-cooled features:
The oil cooler core is placed in the cooling water circuit, and the temperature of the cooling water is used to control the temperature of the lubricating oil. When the temperature of the lubricating oil is high, the temperature of the lubricating oil is reduced by the cooling water. When the engine is started, the heat is absorbed from the cooling water to make the lubricating oil quickly increase the temperature. The oil cooler is composed of a shell made of aluminum alloy, a front cover, a rear cover and a copper core tube. In order to enhance cooling, heat sinks are fitted outside the tube. Cooling water flows outside the tube, and lubricating oil flows inside the tube, and thy exchange heat. There are also structures in which oil flows outside the pipe and water flows inside the pipe.
