Product Details

Gates Molded Coolant Hose 23814 is engineered for the upper cooling circuit on the BMW X3 and is shaped to match the vehicle’s original hose path. The modular hose design includes OE-style integrated components such as quick-connect fittings and a bleeder valve, helping maintain the factory-style coolant connection layout. Gates builds this hose for application-specific fitment, making it a direct replacement choice for 2004, 2005, and 2006 BMW X3 models with the upper hose configuration.

This part cross-references Bosch 16498 and Dayco 72742 for the same application.

Common Cooling System Issues It Can Address

  • Cracked or deteriorated upper radiator hose
  • Coolant leaks at molded hose bends or connector points
  • Damaged quick-connect fittings or bleeder valve connections
  • Restricted coolant flow caused by hose collapse or internal wear
  • Improper hose routing after replacement with a non-molded hose

Installation Notes

Verify the hose routing, connector style, and upper position before installation on the BMW X3. Inspect mating ports, seals, and adjacent cooling system components for wear or contamination before connecting the new hose. Confirm the bleeder valve is positioned correctly during coolant service and follow the vehicle manufacturer’s bleeding procedure after installation.
