Quick facts
- Part: Gates 22373 radiator coolant hose
- Fits: 2005-2009 Buick LaCrosse V6 3.8L and other vehicles
- Position: Lower
- Material: EPDM
- Condition: New
A cracked, swollen or soft cover, coolant seepage near the hose ends, or a hose that collapses can mean it is worn. Look it over only with the engine off and cool. These signs alone do not prove the hose is the problem; a failing water pump can also leak coolant.
Fits
It is listed for a wide range of Buick, Chevrolet, Oldsmobile and Pontiac models, including the 2000-2005 Chevrolet Impala V6 3.8L and the 2005-2009 Buick Allure V6 3.8L, and each takes one. Driving something else? Look up your year, model and engine in the "Vehicles it fits" section.
