Dayco Radiator Coolant Hose P/N:71977
Dayco 73084 lower radiator coolant hose for the 2015-2023 Ford Transit-150 and other vehicles carries coolant through the engine cooling system. This Dayco radiator coolant hose is a branched hose with five ends.
Cracks, a soft or swollen hose, or coolant staining at the ends can mean a radiator coolant hose is wearing out. Coolant loss or overheating alone does not prove this hose is at fault; a bad thermostat is another common cause.
It is listed for a wide range of Ford Transit models, including the 2015-2023 Ford Transit-250 and the 2015-2023 Ford Transit-350. On 2015-2019 models it fits the V6-3.5L and V6-3.7L engines. The 2015-2023 Ford Transit-350 takes one.
