Gates 04-07 Freightliner Business Class M2 Diesel Upper Eng. To Rad. Molded Coolant Hose

This is the upper radiator hose for 2004-2007 Freightliner Business Class M2 trucks with a diesel engine. It connects the engine's water pump outlet to the radiator's top inlet, circulating coolant to keep your engine from overheating. A cracked or leaking hose can quickly lead to serious engine damage, so replacing it with a well-made part like this Gates hose is important for keeping your truck on the road.

Gates is a well-known name in cooling system parts, and this molded hose is built to handle the pressures and temperatures found in a diesel engine's cooling system. Its specific shape is designed to fit the routing of the M2 chassis without kinking or rubbing, ensuring proper coolant flow and preventing premature wear. This hose is made from EPDM rubber, which is resistant to heat and coolant chemicals, helping it last longer than generic rubber hoses.
