Key Features

• EPDM construction for coolant-system durability
• Molded shape for the upper radiator to filler neck route
• 1.19 in. (30 mm) inside diameter at both ends
• 12.5 in. (318 mm) centerline length
• No spring, no modular sections, and no quick-connect fittings
• OE-style replacement hose for select Toyota cooling systems

Product Details

The Gates Molded Coolant Hose line is engineered for radiator, heater, bypass, and other coolant applications where a formed hose is required. Part number 23145 uses EPDM material and a molded profile to match the routing and dimensions needed for the upper radiator to filler neck connection. This makes it a practical replacement for Toyota Yaris cooling system service and related Toyota Avanza applications where the original hose shape matters.

This part cross-references Bosch 66866 and Anchor 9890 for the same application.
