Gates 52399 Radiator Coolant Hose

Overview

The Gates 52399 molded coolant hose is built for specific applications that require an OE-style hose assembly with integrated connection points. It is made from EPDM and plastic and follows the molded layout needed for proper coolant routing in the vehicle’s cooling system.

Compatible with 2012-2014 Volkswagen Passat applications, this radiator coolant hose is identified by part number 52399 and is engineered to match the original hose configuration. Gates 52399 is a direct-fit style replacement for vehicles that use the same molded coolant hose design.

Key Features

• EPDM and plastic construction for coolant system use
• Molded hose design for application-specific routing
• Integrated connector-style features for OE-style fitment
• Built for radiator coolant hose replacement service
• Part number 52399 for easy identification

Product Details

The Gates Molded Coolant Hose line is designed for vehicles that require a shaped hose assembly rather than a universal cut-to-fit hose. Gates 52399 follows the original-style layout and includes integrated OE-type components referenced in the manufacturer description, helping maintain the correct coolant path and connection style. This part cross-references Interchanges (e.g., 5C0122101H, F12179) for the same application.

Fits 2012-2014 Volkswagen Passat, N/A.

Common Replacement Issues

• Cracked or deteriorated coolant hose material
• Leaks at molded hose connection points
• Incorrect hose routing from a non-matching replacement
• Cooling system service needs tied to hose aging

Installation Notes

Verify the hose shape, end sizes, and connector style against the original part before installation. Confirm the application uses the same molded coolant hose configuration and part number 52399.

Quality Assurance

Gates is a recognized aftermarket supplier in modular coolant hose assemblies, and this hose is manufactured to application-specific OE-style requirements.
