Product Line Details

Gates Molded Coolant Hose products are engineered for upper, lower, bypass, heater, and other coolant routing needs. This line is built to replace OE-style hoses with application-specific shapes and dimensions, reducing the need to source the hose from a dealer for routine radiator hose replacement. Part number 23631 is part of that molded hose range and is specified for the lower cooling circuit on select Volkswagen models.

Vehicle Fitment

• Fits 2006-2010 Volkswagen Beetle, lower.
• Fits 2010 Volkswagen Beetle Cabrio, lower.

This part cross-references Dayco 72646 and Four Seasons 66403 for the same application.

What It Helps Address

• Cracked or deteriorated lower radiator hose
• Coolant leaks at the hose body
• Improper hose routing from a previous replacement
• Restricted coolant flow caused by hose collapse or deformation
• Service delays when the OE-style hose is no longer on hand

Installation Notes

Verify hose routing, end diameters, and centerline length against the original part before installation. Inspect adjoining clamps, fittings, and coolant connections for wear or corrosion, and confirm the cooling system is properly filled and bled after service. For best results, replace the hose only after the engine has cooled completely.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications using EPDM material and application-specific dimensions for the listed Volkswagen Beetle and Beetle Cabrio fitments. Part number 23631 is built for direct replacement use in the lower radiator hose position.
