Will the CU2691 fit my specific vehicle model and year?

The CU2691 is made to match original equipment dimensions and mounting locations for compatible Nissan Armada, Nissan Titan, and INFINITI QX56 applications. To guarantee correct fitment for your exact year and trim, use the vehicle fitment/confirm tool where this product is listed or check part cross-reference guides.

• Direct-replacement design matches OE mounting points and hose connections.
• Includes accessory pack for a straightforward installation.
• Verify fitment by entering vehicle details in the confirmed-fit tool.

How does this radiator improve cooling performance?

Heat transfer is optimized through a high-density core that increases air contact with cooling surfaces. The multi-louvered fins and fin spacing are chosen to balance airflow and coolant flow, helping to dissipate engine heat effectively under normal driving and towing loads.

• High-density multi-louvered fin core for improved thermal exchange.
• Carefully designed flow paths for consistent coolant circulation.
• Aluminum construction for efficient heat conduction and reduced weight.

What should I expect during installation of the CU2691?

Installation follows the same steps as the factory radiator due to the radiator’s drop-in geometry. The included accessory pack contains mounting hardware and fittings typically required to replace the original unit, reducing the need to source additional parts.

• Drop-in fit reduces modification and adjustment time.
• Accessory pack includes common brackets, seals, and fasteners.
• Recommended to inspect hoses, clamps, and thermostat during replacement.

Is the Spectra Premium radiator durable and tested?

Spectra Premium radiators are subjected to quality control and endurance testing aimed at replicating real-world thermal and environmental conditions. Materials and assembly techniques are selected to resist corrosion and maintain structural integrity over time.

• Manufactured with corrosion-resistant aluminum and reinforced tanks.
• Rigorously tested for reliability under varied temperature and pressure cycles.
• Built to meet or exceed performance expectations of the original equipment.

Who is this radiator for? The Spectra Premium CU2691 is intended for owners and technicians replacing a worn, damaged, or underperforming radiator in compatible Nissan Armada, Nissan Titan, and INFINITI QX56 models. It suits DIY mechanics who want a direct-replacement part with included installation hardware, as well as shops that need a reliable aftermarket unit that maintains original mounting and cooling characteristics. If you require a radiator that fits without modification, emphasizes thermal efficiency, and comes from a manufacturer focused on matched OE-style performance, the CU2691 is a practical option.
