The Gates molded lower coolant hose for 2018–2021 Freightliner Business Class M2 with the Cummins L9 diesel is a vehicle-specific lower hose that connects pipe to engine. Molded to match the truck's original routing, it replaces worn or damaged lower hoses to help maintain proper coolant circulation in heavy-duty diesel applications and reduce the risk of leaks at the lower cooling connections.
