The Cummins 4970849 Water Transfer Tube is a component designed to facilitate the efficient transfer of coolant within the cooling system of commercial trucks. Its role is significant in maintaining optimal engine temperature, which is vital for the performance and longevity of the engine ¹.

Basic Concepts of Water Transfer Tubes

A water transfer tube is a conduit within the cooling system that allows coolant to flow between the engine and the radiator. This flow is crucial for dissipating heat generated by the engine, ensuring that the engine operates within safe temperature ranges. The tube operates by providing a direct pathway for coolant, which absorbs heat from the engine and transfers it to the radiator where it is dissipated into the environment ².

Purpose of the 4970849 Water Transfer Tube

This Cummins part plays a role in the truck’s cooling system by enabling the movement of coolant between the engine and radiator. This facilitates efficient heat exchange, which is necessary for maintaining engine temperature within specified limits. By ensuring a consistent flow of coolant, the tube helps prevent overheating, which can lead to engine damage.
