  Motorcraft™ Overflow Hose, Hose

• Description:

  The Motorcraft KM-5411 is the engine coolant overflow hose for the 2015-2019 Ford Transit. This hose connects the cooling system to the coolant reservoir, allowing expanding coolant to flow into the tank as the engine warms and to be drawn back as it cools, which keeps the system full and properly pressurized. Overflow and recovery hoses are smaller and lower pressure than the main radiator hoses, but the rubber still ages, hardening and cracking or splitting at the connection points and reservoir barbs. A driver looking for this part is often noticing a slowly dropping coolant level, coolant seepage near the reservoir, a faint coolant odor, or a hose that has become brittle and split. Replacing a failed overflow hose restores the system's ability to manage coolant expansion and prevents air from being drawn into the circuit, which can cause hot spots and inaccurate coolant levels. As a genuine Ford Motorcraft molded hose, the KM-5411 matches the factory routing, diameter, and connection geometry so it fits the reservoir and mating fittings correctly without leaks. After fitting the new hose, top off with Motorcraft specification coolant, confirm the reservoir cap seals properly, and check for a stable coolant level once the engine reaches operating temperature. Confirm your Transit application before ordering.
