Cummins®

The Cummins 3926670 Oil Cooler is a component designed to regulate the temperature of engine oil in heavy-duty trucks. Its role is significant in maintaining the efficiency and longevity of the engine. By ensuring that the oil remains within optimal temperature ranges, this part contributes to the overall performance and reliability of the truck’s engine system ¹.

Basic Concepts of Oil Coolers

An oil cooler is a device that helps manage the temperature of engine oil by dissipating excess heat. It operates on the principle of heat exchange, where the hot oil transfers its heat to a cooler medium, typically air or coolant, as it passes through the cooler’s fins or tubes ². This process ensures that the oil maintains a temperature that allows for efficient lubrication and protection of engine components.

Purpose of the Cummins 3926670 Oil Cooler

The Cummins 3926670 Oil Cooler is designed to maintain optimal oil temperature, which is vital for efficient engine performance and longevity. By regulating the oil temperature, it helps to ensure that the oil retains its viscosity and lubricating properties, reducing friction and wear on engine parts ³. This, in turn, contributes to stable engine operation and extends the engine’s service life.
