Gates Radiator Coolant Hose P/N:21170
Gates 51852 lower radiator coolant hose for the 2017-2019 Ford F-250 Super Duty V8 6.2L and other vehicles carries engine coolant between the connector and the engine. This is a Gates molded coolant hose made for specific applications.
A coolant leak, a soft or collapsed hose, or cracks and swelling in the rubber can mean the hose is worn, but those signs alone do not prove it; a loose clamp can leak in the same way. Look only with the engine off and cool.
This hose is a direct-fit replacement for the 2017-2019 Ford F-250 Super Duty V8 6.2L and the 2017-2019 Ford F-350 Super Duty V8 6.2L. Each of these trucks takes one.
