Cummins®

The Cummins Water Inlet Hose, part number 3917424, is a critical component in the cooling systems of heavy-duty trucks. It facilitates the flow of coolant into the engine, ensuring optimal temperature management and contributing to the engine’s efficiency and longevity ¹.

Basic Concepts of Water Inlet Hoses

A water inlet hose serves as a conduit for coolant to enter the engine block from the radiator. It ensures a continuous supply of coolant, which absorbs heat from engine components, maintaining optimal engine temperature and preventing overheating ².

Purpose of the 3917424 Water Inlet Hose

This Cummins part is integral to the coolant circulation process in a truck’s engine. It allows coolant to flow from the radiator into the engine block, where it absorbs heat. The coolant then returns to the radiator, releasing the absorbed heat into the air, completing the cycle. This continuous circulation is vital for maintaining the engine’s temperature within specified limits ³.

Key Features

The 3917424 is constructed with materials that offer durability and resistance to the high temperatures and pressures found in heavy-duty truck engines. Its design includes reinforced ends for secure connections and a flexible body that accommodates engine movement without compromising the flow of coolant ⁴.

Benefits

This part provides several advantages, including improved coolant flow due to its design, which minimizes restrictions. It also exhibits resistance to high temperatures and pressures, ensuring reliable performance under demanding conditions. Additionally, its construction contributes to longevity, reducing the frequency of replacements ⁵.

Installation Process
