Product Details
The Dayco Curved Radiator Hose line is built for formed coolant routing where a straight hose will not maintain the proper path or clearance. Part number 72122 uses EPDM material for heat and coolant exposure, while the dual inside diameters support the transition between different connection sizes in the cooling system. This makes the Dayco 72122 a practical choice for radiator hose replacement on Chevrolet and GMC trucks and other General Motors vehicles that use this hose profile.
This part cross-references Gates 22706 and NAPA 9339 for the same application. If you are replacing a worn or leaking coolant hose on a Chevrolet, GMC, or General Motors vehicle, Dayco 72122 is a direct-fit style radiator coolant hose built to match the required formed shape and SAE specifications.
What It Helps Fix
- Coolant leaks from cracked or aged radiator hose rubber
- Softening, swelling, or collapse in the hose under heat and pressure
- Improper hose routing caused by a damaged formed hose
- Coolant loss from loose or deteriorated hose connections
- Chafing in routed areas where a protective sleeve is needed
Installation Notes
Inspect the mating necks, clamps, and surrounding cooling-system components before installation. Confirm the end diameters and hose routing match the original application, especially on Chevrolet and GMC vehicles where formed hoses must clear belts, pulleys, and nearby engine components. Replace any damaged clamps and refill the cooling system with the correct coolant after installation.
Quality Assurance
Dayco manufactures this hose to SAE J20R4 Class D-1 and SAE J1684 Type EC requirements, supporting consistent material and dimensional standards for radiator coolant service. Part number 72122 is built as a formed replacement hose for cooling-system repair.
