Gates 52459 Radiator Coolant Hose - Lower

Product Overview

The Gates 52459 molded coolant hose is built for specific applications that require an OE-style modular hose assembly. It uses EPDM and plastic construction and integrates application-specific features such as branches and quick-connect interfaces for a precise cooling-system connection.

Compatible With Audi A4, Audi A4 allroad, Audi A4 Quattro, Audi A5, Audi A5 Quattro, and Audi A5 Sportback applications in the lower cooling circuit. The Gates Molded Coolant Hose line focuses on application-specific routing and integrated components that match the needs of modern cooling systems.

Key Features

• OE-style modular coolant hose construction for specific applications
• EPDM and plastic materials for cooling-system use
• Integrated branch and quick-connect features where required
• Application-specific molded routing for a direct replacement profile
• Part number 52459 for easy identification

Detailed Description

Gates 52459 is a radiator coolant hose designed around modular assembly requirements rather than a universal cut-to-fit layout. The molded design follows the application’s routing needs and incorporates essential OE-style elements such as hose branches, quick connectors, and related integrated features. This makes it a practical choice for Audi A4 and Audi A5 platform cooling-system service where the original hose assembly uses molded connections and specific geometry.

This part cross-references Gates (e.g., 8W0122055BN, F12044) for the same application. The 52459 part number is also useful when verifying replacement against the original hose assembly during cooling-system repair.

What It Is Used For

• Replacing a leaking or cracked radiator coolant hose
• Restoring proper coolant flow through a molded hose assembly
• Addressing damaged quick-connect or branch-style hose sections
• Correcting fitment issues caused by an incorrect hose routing profile
• Servicing cooling-system components on Audi A4 and Audi A5 applications

Installation Notes and Tips

Verify the vehicle’s year, model, and lower-position hose routing before installation. Compare the original hose shape, connector style, and branch layout to the 52459 assembly to confirm the correct application. Because this hose uses molded and integrated features, it should be matched to the exact cooling-system configuration listed in the fitment data.

Quality Assurance

Gates is recognized in the automotive aftermarket for modular coolant hose assemblies that follow application-specific OE-style requirements. Part number 52459 is built to align with those specifications for the listed Audi applications.
