Product Details

Gates Molded Coolant Hose line products are built for vehicles that use modular coolant assemblies with integrated components. This Gates 51756 hose follows that approach with a molded EPDM body and a quick-connect fitting, helping maintain the original hose routing and connection style used in the cooling system. It is a fitment-specific radiator coolant hose for Mini Cooper applications, including reservoir-to-thermostat routing on the Cooper, Cooper Countryman, and Cooper Paceman.

This part cross-references Genuine 17122754573 for the same application.

What This Hose Helps Address

• Coolant leaks from a cracked or aged hose
• Improper fit from a non-matching replacement hose
• Damaged quick-connect connection at the cooling system interface
• Heat-related hose deterioration in the engine bay
• Loss of correct reservoir-to-thermostat coolant routing

Installation Notes and Tips

Verify the vehicle’s year, model, and reservoir-to-thermostat hose routing before installation. Inspect the mating connector and surrounding cooling system components for wear, contamination, or damage before connecting the new hose. Confirm that the hose follows the original molded path and that the quick connector seats fully at the intended connection point.
