Detailed Description

Gates 22373 is a molded radiator coolant hose engineered to follow the factory hose path and connect to the cooling system with the correct molded shape and end sizes. The EPDM material is commonly used in coolant applications because it is suited to heat and fluid exposure in the engine bay. This hose is listed for lower-position use on 2005-2009 Buick Allure, 2005-2009 Buick LaCrosse, 1997-2008 Pontiac Grand Prix, 2000-2005 Chevrolet Impala, 2000-2005 Chevrolet Monte Carlo, 1997-2004 Buick Regal, and 1998-1999 Oldsmobile Intrigue.

This part cross-references Dayco 71591 and Continental 62444 for the same application. Gates 22373 is a practical choice when replacing a worn lower radiator hose on a Chevrolet Impala, Chevrolet Monte Carlo, or Pontiac Grand Prix with the listed fitment.

Common Problems This Hose Can Address

• Replacement needs for a damaged hose on a Buick Regal, Chevrolet Impala, or Pontiac Grand Prix

Installation Notes and Tips

Verify the vehicle year, make, model, and lower hose routing before installation.
