Gates 23971 Radiator Coolant Hose - Upper

Overview

Gates 23971 is a molded radiator coolant hose built for upper coolant routing with OEM-quality specifications. It uses EPDM construction and a molded shape to match the required path for a clean, direct replacement on select Nissan vans.

Key Features

• EPDM rubber construction for coolant system service.
• Molded design follows the required hose path.
• 1.3-inch inside diameter at both ends.
• 26.5-inch centerline length for the specified application.
• Fits upper coolant applications with OEM-quality specifications.

Detailed Description

This Gates Molded Coolant Hose, part number 23971, is engineered for upper radiator coolant routing on 2012-2017 Nissan NV2500 and 2012-2017 Nissan NV3500 applications. The molded profile helps the hose follow the original routing geometry, while EPDM material provides the construction commonly used in cooling-system service. Gates positions this molded coolant hose line as a broad replacement offering for radiator hose applications, including upper, lower, bypass, and heater hose needs.

This part cross-references Monroe Shocks & Struts (e.g., 27102X, 215011PD0A) for the same application.

What It Helps Address

• Cracked or deteriorated coolant hose material.
• Incorrect hose routing from a non-molded replacement.
• Coolant leaks at the hose body or connection points.
• Fitment issues on upper radiator hose applications.

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. This hose is molded and does not use a modular design, so it should be matched to the original application layout. Confirm the vehicle uses the upper hose configuration listed in the fitment data for the Nissan NV2500 or Nissan NV3500.

Quality Assurance

Gates manufactures molded coolant hoses to OEM-quality specifications for replacement use in cooling systems.
