Detailed Description

This Gates molded coolant hose is engineered for radiator and engine coolant routing where a formed hose is required. The EPDM material is commonly used in cooling system hoses for its resistance to heat and coolant exposure, while the molded profile helps maintain the intended path between connection points. For 2019-2025 Nissan Altima models, this hose serves the lower position from the connector to the engine. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Cracked or hardened lower coolant hose material
• Coolant seepage at hose connection points
• Incorrect hose routing after a cooling system repair
• Restricted coolant flow caused by a deteriorated hose
• Replacement needs on 2019-2025 Nissan Altima lower hose service

Installation Notes

Verify hose routing, end diameters, and centerline length before installation. Inspect adjoining clamps, connectors, and engine fittings for wear or corrosion before transferring the hose into service. Confirm the hose position matches the lower - connector to engine application on the vehicle.
