Water Inlet Connection
Cummins®

The Water Inlet Connection (Part #4931252) by Cummins is a component designed for use in commercial truck engine cooling systems. Its purpose is to facilitate the entry of coolant into the engine block, ensuring efficient heat dissipation and maintaining optimal engine operating temperatures.

Basic Concepts of Water Inlet Connection

Water inlet connections in engine cooling systems are designed to allow coolant to enter the engine block. These connections are essential for the circulation of coolant, which absorbs heat from the engine and transfers it to the radiator where it is dissipated. The design and placement of the water inlet connection play a significant role in the effectiveness of the cooling process ¹.

Purpose and Function

The Water Inlet Connection serves to direct coolant into the engine block, where it circulates through passages to absorb heat generated by combustion. By ensuring a steady flow of coolant, this component helps maintain the engine’s temperature within specified limits, which is vital for engine efficiency and longevity. It integrates into the cooling system by connecting to the thermostat housing and the engine block, creating a pathway for coolant entry ².

Key Features

The Cummins Water Inlet Connection is engineered with several design elements that enhance its performance and durability. These include a precision-machined fitting to ensure a tight seal, corrosion-resistant materials to withstand the harsh chemicals in coolant, and a robust construction to endure the high pressures and temperatures within the engine cooling system ³.

Benefits

The Water Inlet Connection offers several benefits, including improved coolant flow which enhances the engine’s cooling efficiency. It also provides enhanced engine protection by ensuring consistent coolant levels and pressure, which prevents overheating. Additionally, the component’s durable construction contributes to the overall reliability of the engine cooling system.

Installation and Compatibility

Proper installation of the Water Inlet Connection is vital for the integrity of the engine cooling system. It should be installed according to the manufacturer’s guidelines to ensure a secure fit and proper function. Compatibility with various Cummins engine models is an important consideration, as it ensures that the component will fit and function correctly within the specific engine design.

Maintenance and Troubleshooting

Routine maintenance of the Water Inlet Connection involves checking for leaks, ensuring the connection is secure, and inspecting for signs of wear or corrosion. If issues arise, such as coolant leaks or inconsistent engine temperatures, troubleshooting may involve inspecting the connection for proper seating, checking for damage, and ensuring that all related components are functioning correctly.

Role of Part 4931252 Water Inlet Connection in Engine Systems

The part 4931252 Water Inlet Connection is integral to the efficient operation of various engine systems. It serves as the primary interface for the introduction of water into the engine’s cooling system. This component ensures a secure and leak-free connection between the water supply and the engine’s water pump.

In the context of the engine’s cooling system, the Water Inlet Connection facilitates the flow of coolant from the reservoir to the water pump. The water pump then circulates the coolant through the engine block and cylinder head, absorbing heat generated during combustion.

The Water Inlet Connection also interacts with the thermostat housing, allowing for regulated coolant flow based on engine temperature. This ensures that the engine operates within optimal temperature ranges, preventing overheating.

Additionally, this component is linked to the radiator hoses, which transport coolant between the engine and the radiator. The radiator then dissipates heat through its fins and fans, cooling the coolant before it returns to the engine via the Water Inlet Connection.

In summary, the part 4931252 Water Inlet Connection is a key element in maintaining the thermal stability of the engine, ensuring reliable performance and longevity of the engine components.

Conclusion

The Water Inlet Connection (Part #4931252) by Cummins plays a critical role in the engine cooling system by facilitating the efficient flow of coolant into the engine block. Its design features, such as precision machining and corrosion-resistant materials, ensure durability and reliability. Proper installation and maintenance are essential for the component’s effective function, contributing to the overall performance and longevity of Cummins engines.
