Dayco Radiator Coolant Hose P/N:70539
Dayco 72779 lower radiator coolant hose for the 2013-2019 Nissan Sentra carries coolant between the radiator and the engine. This Dayco coolant hose is a direct-fit replacement for the lower position on this car.
A lower radiator coolant hose that is wearing out can show cracks, bulges, a soft spongy feel or coolant seepage at its ends. Check it only with the engine off and cool. These signs alone do not prove the hose is the problem, since a weak radiator cap can cause coolant loss too.
This hose fits the 2013-2016 Nissan Sentra and the 2017-2019 Nissan Sentra L4-1.8L. The car takes one, and this listing is one hose.
