Introduction to Electronic Control Coolers

Electronic control coolers (ECCs) are indispensable components in modern commercial trucks, ensuring optimal engine performance and longevity. These devices regulate the temperature of the engine’s electronic control unit (ECU), preventing overheating and ensuring reliable operation ¹.

How an Electronic Control Cooler Works

An electronic control cooler operates by circulating coolant through a heat exchanger. The coolant absorbs heat from the ECU and dissipates it through the radiator. This process maintains the ECU at an optimal operating temperature, which is crucial for the efficient functioning of the engine’s electronic systems ².
