Gates 23809 Radiator Coolant Hose

Gates Molded Coolant Hose 23809

The Gates 23809 molded coolant hose is built for specific modular cooling-system applications and follows OEM-style construction details. It is made for vehicles that use integrated hose routing with branches and molded connections, including Chevrolet Volt and Cadillac ELR applications.

Key Features

• EPDM and plastic construction for coolant-system service.
• Molded modular hose design with two branches.
• Built to match application-specific routing and connection points.
• Designed around OEM-style integrated components.
• Compatible with modular cooling layouts used on Chevrolet Volt and Cadillac ELR.

Detailed Description

Gates 23809 is a molded radiator coolant hose for modular cooling systems that require branched routing rather than a straight universal hose. The design uses EPDM and plastic materials and is shaped to follow the factory hose path, with branch points that align to the cooling circuit layout. This part number is used in fitments such as 2011-2015 Chevrolet Volt and 2014-2016 Cadillac ELR, where the hose connects between reservoir, tee, engine, heater control valve, and pipe locations depending on the application. Gates 23809 is part of the Molded Coolant Hose line, which focuses on application-specific hose assemblies built to mirror OEM-style integrated features.

This part cross-references Monroe Shocks & Struts (e.g., 27070X, 20893319) for the same application.

What It Is Used For

• Replacing a molded coolant hose with branched routing.
• Restoring coolant flow through a factory-style modular hose path.
• Addressing leaks caused by aged EPDM hose material.
• Replacing a damaged hose assembly with molded connection geometry.
• Servicing cooling-system routing on Chevrolet Volt and Cadillac ELR applications.

Installation Notes and Tips

Verify the hose routing, branch count, and connection layout against the vehicle’s cooling diagram before installation. Confirm the molded shape and end sizes match the original hose assembly for the specific application. Because this is an application-specific modular hose, correct routing is important for proper fitment on the Chevrolet Volt and Cadillac ELR.
