Water Inlet Connection
Cummins®

The Water Inlet Connection 4940727 by Cummins is a component designed to facilitate the flow of coolant into the engine cooling system of heavy-duty trucks. Its role is significant in maintaining the optimal operating temperature of the engine, thereby contributing to the overall efficiency and reliability of the vehicle ¹.

Basic Concepts of Water Inlet Connection

Water inlet connections in heavy-duty trucks are integral to the cooling system. They allow coolant to enter the engine block, where it absorbs heat generated during combustion. The coolant then circulates through the engine, transferring heat away from critical components and back to the radiator, where it is cooled before re-entering the system. This continuous cycle is vital for preventing engine overheating and ensuring consistent performance ².

Purpose of the 4940727 Water Inlet Connection

The 4940727 specifically serves to direct coolant into the engine’s water jacket. By ensuring a steady and unobstructed flow of coolant, it plays a role in the engine cooling system by maintaining an even temperature distribution throughout the engine block. This helps in preserving the integrity of engine components and enhancing the engine’s operational efficiency ³.
