Coolant Line
Detroit Diesel

A durable stainless steel coolant line featuring nipple fittings, this part is designed to transport engine cooling fluid with high reliability in harsh operating conditions. Stainless construction offers excellent corrosion resistance, enabling longevity in the hot, chemically aggressive environment of the cooling system. The nipple fittings provide simple, secure connections that resist loosening under vibration and thermal expansion, supporting leak-free performance across a wide temperature range. This line is intended for use in primary or secondary cooling circuits where robust flow paths are critical for maintaining target engine temperatures and preventing overheating during heavy-duty operation. The VMRS code 043-001-177 places it within the coolant line subcategory, which supports proper maintenance planning and replacement scheduling. Compatibility is framed by Detroit Diesel platform requirements, and the item is commonly matched with standard hose clamps and mounting hardware used throughout the cooling system. Cross references are not listed, underscoring its role as a straightforward, OEM-aligned coolant routing solution.
