Dayco Radiator Coolant Hose P/N:71741
Dayco 71850 radiator coolant hose for the 2005-2009 Buick LaCrosse V6 3.8L and other vehicles carries coolant between the engine and the radiator. It is a direct-fit replacement for the vehicles it fits.
A hose that is cracked, swollen or seeping coolant may need replacing. Look it over with the engine off and cool. Overheating or a falling coolant level alone does not prove the hose is at fault, since a weak radiator cap is also a common cause.
The vehicles it fits include the 2005-2009 Buick LaCrosse V6 3.8L, the 2000-2005 Chevrolet Impala V6 3.4L or 3.8L and the 2005-2009 Buick Allure V6 3.8L. A 2005-2009 Buick LaCrosse V6 3.8L takes one.
