Product Details

Gates Molded Coolant Hose line is engineered for upper, lower, bypass, heater, and other coolant system applications using OEM-quality specifications. The Gates 23119 is a molded radiator coolant hose for select 2005-2009 Buick, Chevrolet, and Pontiac models, including the Buick Allure, Buick LaCrosse, Chevrolet Impala, Chevrolet Monte Carlo, and Pontiac Grand Prix. This part number 23119 is also referenced in replacement listings for the same application, including Bosch 9780 and Dayco 72366.

For buyers searching for a 2008-2009 Buick Allure upper radiator hose, 2008-2009 Buick LaCrosse upper coolant hose, or 2006-2009 Chevrolet Impala upper heater and radiator hose routing, this molded EPDM hose provides the correct formed shape for the listed vehicles. Gates 23119 is also listed for Pontiac Grand Prix upper hose applications, including 2005-2008 models and 2006 variants with first- and second-design notes.

What It Helps Address

  • Cracked or leaking upper radiator hose

  • Incorrect hose routing after replacement
  • Coolant loss from aged molded hose sections
  • Fitment issues on upper hose service for listed Buick, Chevrolet, and Pontiac models

Installation Notes and Tips

Verify the vehicle year, make, model, and upper-position fitment before installation. Compare the original hose shape, end diameters, and centerline length to the removed part, especially on 2006 Pontiac Grand Prix applications with first-design or second-design notes. Inspect hose clamps, mating necks, and nearby cooling system components for wear before installing the new hose.
