Dayco Radiator Coolant Hose P/N:71977
Dayco 73045 upper radiator coolant hose for the 2010-2013 Land Rover Range Rover Sport and other vehicles carries coolant between the engine and the radiator.
A coolant leak at a hose end, cracks, swelling or a soft spot in the hose can mean it is aging. Low coolant alone does not prove this hose is the problem, since a leaking water pump can cause it too.
This hose is a direct-fit replacement for the 2010-2013 Land Rover Range Rover Sport, the 2010-2013 Land Rover LR4 and the 2011 Land Rover Range Rover V8 5.0L.
