Detailed Description

Gates 23813 is a molded radiator coolant hose engineered for the lower position on 2004-2006 BMW X3 vehicles. The hose uses an OE-style modular layout with integrated components, including female quick connectors and a sensor port, to match the original cooling system configuration. If you are replacing a lower BMW X3 coolant hose, this part number 23813 provides the correct molded routing and connection style for the listed application.

The Gates Molded Coolant Hose product line is built around vehicle-specific fitment and OE-type component integration. That makes it a practical choice when the original hose includes molded branches, quick-connect interfaces, or sensor provisions rather than a simple straight hose. This Gates 23813 hose is also a useful reference for shoppers searching for a BMW X3 lower radiator hose, molded coolant hose, or OE-style coolant hose replacement.

This part cross-references Dayco 72802 for the same application.

What It Helps Address

• Coolant leaks from a cracked or aged lower hose
• Loss of coolant flow caused by hose deterioration
• Broken or worn quick-connect interfaces
• Fitment issues after replacing a molded OE hose
• Sensor-port related hose replacement needs

Installation Notes and Tips

Confirm the lower hose routing and connector style against the removed part before installation. Inspect adjoining fittings, clamps, and sealing surfaces for wear, corrosion, or residue that could affect the seal. Because this hose includes molded and modular features, align the hose carefully to avoid twisting or stress at the quick-connect ends.
