Gates 16-17 Freightliner Cascadia ISX15 Diesel Upper Rad. To Pipe Straight Coolant Hose (4-Ply)

This 4-ply coolant hose from Gates is built to handle the demands of the ISX15 diesel engine in your 2016-2017 Freightliner Cascadia. It connects the upper radiator to the pipe, ensuring coolant circulates properly to keep your engine running at the right temperature. The multi-ply construction is key here, offering the strength and flexibility needed to resist the heat and pressure cycles common in heavy-duty diesel applications.

Gates uses a robust EPDM rubber compound for the inner tube and cover, which is known for its excellent resistance to coolant chemicals, heat, and ozone. This means the hose is less likely to crack or degrade over time, even under constant operation. The reinforcement plies are strategically placed to give the hose its shape and prevent collapse under vacuum, while still allowing it to flex as the engine moves. It’s designed to fit right where the original hose was, making installation straightforward for a mechanic.

When you're replacing a coolant hose, it's always a good idea to inspect the surrounding components, like the radiator, thermostat, and other hoses, to make sure everything is in good shape. This Gates hose is a solid option for keeping your Cascadia's cooling system in top working order.
