Coolant Line
Detroit Diesel

The coolant line assembly is designed to facilitate efficient transmission of coolant within the engine cooling system, playing a crucial role in maintaining optimal operating temperatures. Made from resilient nylon tubing, it combines flexibility with strength, resisting high temperatures and pressure fluctuations that are typical in diesel engine environments. Its black coloration helps it withstand UV exposure and environmental wear, extending service life. The assembly’s design ensures a secure connection with minimal risk of leaks, which is vital for preventing engine overheating and subsequent damage. Proper routing of this line reduces thermal stress on surrounding components, contributing to overall engine reliability. Technicians rely on high-quality assemblies like this to ensure seamless coolant flow and prevent costly repairs. Source One Parts Center supplies these assemblies, emphasizing their importance in maintaining engine efficiency and durability in heavy-duty applications.
