Cummins®

The Cummins 3040099 Water Inlet Tube is a component designed for use in the cooling systems of heavy-duty trucks. Its primary function is to facilitate the efficient flow of coolant into the engine, thereby playing a role in maintaining optimal engine temperature and ensuring the longevity and performance of the engine ¹.

Basic Concepts of Water Inlet Tubes

Water inlet tubes are integral components within an engine cooling system. They serve to direct coolant from the radiator into the engine block, where it absorbs heat generated by combustion. The coolant then circulates back to the radiator, where it releases the absorbed heat and cools down before re-entering the engine. This continuous cycle is vital for maintaining engine temperature within a specified range, which is important for engine efficiency and durability ².

Purpose of the Cummins 3040099 Water Inlet Tube

The Cummins 3040099 Water Inlet Tube is specifically engineered to enhance the coolant flow within a truck’s engine cooling system.
