Product Details

Gates Molded Coolant Hose 51907 is engineered to match the shape and connection points used in the original coolant hose layout. Gates builds this modular coolant hose to application-specific dimensions and integrates OE-style features such as branches and connector interfaces where required. That makes it a practical replacement for vehicles that need the reservoir-to-connector hose path restored without altering the factory routing.

This part cross-references GM 23228909 and F11329 for the same application. It is a direct-fit option for 2014-2018 Chevrolet Silverado 1500, 2014-2018 Chevrolet Silverado 2500, 2014-2018 GMC Sierra 1500, and 2015-2018 GMC Yukon models, along with other listed Cadillac, Chevrolet, and GMC applications. The Gates 51907 part number is also the key identifier when matching the hose to the correct vehicle configuration.

What This Hose Helps Address

• Cracked or deteriorated coolant hose material

Installation Notes

Verify the vehicle’s year, make, model, and reservoir-to-connector routing before installation. Compare the original hose shape, branch location, and connector style to the Gates 51907 hose to confirm match-up.
