Dayco Radiator Coolant Hose P/N:81131
Dayco 72402 upper radiator coolant hose for the 2006-2015 Honda Civic 4-cylinder 1.8L and other vehicles carries coolant between the filler neck and the engine. A worn Dayco radiator coolant hose can show cracks, swelling or coolant seepage at its ends.
With the engine off and cool, you can look the hose over for those signs. A leak or overheating can also start at a clamp, another hose or the radiator, so trace where the coolant is escaping before you buy a hose.
The 2006-2015 Honda Civic 4-cylinder 1.8L, the 2013-2019 Nissan Sentra and the 2016-2022 Honda HR-V take this hose, along with other vehicles. Each car needs one, at the upper run between the filler neck and the engine.
