Introduction

The Cummins 4398434 Radiator is a component designed for use in heavy-duty trucks. Its primary function is to maintain the engine’s optimal operating temperature by dissipating heat from the engine coolant. This radiator is integral to the engine cooling system, ensuring that the engine operates efficiently and reliably under various conditions.

Basic Concepts of Radiators

Radiators operate on the principle of heat exchange. They facilitate the transfer of heat from the engine coolant to the ambient air, thereby cooling the coolant before it recirculates back into the engine. Maintaining optimal engine temperature is vital for engine efficiency, longevity, and performance ¹. A typical radiator system comprises a core, tanks, hoses, and a thermostat. The core, made up of tubes and fins, is where the heat exchange occurs. Tanks hold the coolant, while hoses connect the radiator to the engine. The thermostat regulates the flow of coolant based on engine temperature.
