Genuine OEM Upper Radiator Coolant Hose & Filler Neck for 2007-2013 Nissan Altima 2.5L (21501-9HA0A

Prevent persistent coolant leaks and engine overheating with this Genuine OEM Upper Radiator Hose Assembly with Water Filler Neck for 2007–2013 Nissan Altima models.

On the 2.5L Nissan Altima, the plastic coolant filler neck housing integrated into the upper radiator hose becomes brittle over time due to constant thermal cycles. Cracks, hairline fractures, or distorted filler necks lead to pressure loss, coolant seepage, and dangerous engine overheating. Replacing your worn upper hose assembly with an original factory component (MPN: 21501-9HA0A) restores a pressure-tight seal and ensures smooth coolant circulation through your engine bay.

Key Features & Benefits:

Heavy-Duty Heat Resistance: Molded from factory-grade EPDM rubber and reinforced plastic built to withstand high cooling system pressure and extreme temperatures.

OEM Integrated Filler Neck: Engineered to original factory tolerances to ensure your pressure radiator cap seals tight without leaking air into the system.

Direct Factory Replacement: Pre-shaped bends guarantee perfect clearance around engine bay components for a seamless, bolt-on installation.
