Gates 23500 Molded Coolant Hose

Gates 23500 is a molded radiator coolant hose built to OE-style specifications for the cooling system. It is formed from EPDM for durability and is shaped for the upper hose route from the filler neck to the engine on select Nissan Altima models.

Compatible with 2007-2011 Nissan Altima, upper - filler neck to engine, this molded coolant hose supports a direct replacement for the original radiator hose path. Gates Molded Coolant Hose line covers upper, lower, bypass, heater, and other coolant applications with application-specific fitment.

  • EPDM construction for coolant-system service
  • Molded shape for the specified hose routing
  • 1.3 in. inside diameter at both ends
  • 28.5 in. centerline length

Product Details

This Gates 23500 radiator coolant hose is engineered for the upper hose position on 2007-2011 Nissan Altima applications listed in the fitment data. The molded design follows the original routing from the filler neck to the engine, helping maintain proper hose alignment in the cooling system. Gates 23500 is part of the Molded Coolant Hose line, which is built around replacement coverage for common coolant hose locations without requiring a universal-form fit.

This part cross-references Remy 16236 for the same application.

Common Replacement Issues

  • Cracked or split upper radiator hose
  • Coolant leaks at the filler neck-to-engine hose route
  • Softened or swollen hose material from heat exposure
  • Incorrect hose shape after prior repair work
  • Restricted cooling-system flow from a deteriorated hose

Installation Notes

Verify the hose routing, end diameters, and centerline length before installation. Confirm the vehicle is a 2007-2011 Nissan Altima with the upper - filler neck to engine hose position listed in the fitment data. Inspect adjoining necks and clamps for wear, and replace any damaged sealing surfaces before installing the new hose.

Quality Assurance

Gates manufactures this molded coolant hose to OEM-quality specifications for radiator hose replacement applications. The Gates Molded Coolant Hose line is positioned as a broad replacement offering for coolant-system service across upper, lower, bypass, heater, and related hose locations.
