autoexact Aluminum Radiator for Nissan Armada/Titan (2004–2015) — Direct-Fit, Pressure-Tested Cooling

Autoexact’s all-aluminum radiator is a direct-fit replacement engineered to restore reliable cooling for 2004–2015 Nissan Armada, 2004–2015 Nissan Titan, and 2004–2010 INFINITI QX56 vehicles.

Replace a worn or leaking radiator with a unit designed to meet OEM dimensions and performance expectations without modifications. This radiator combines multi-louvered fins, flat-flow B-type tubes, and corrosion-resistant coatings to improve heat transfer and resist long-term wear. It arrives pressure-tested and ready to connect to existing hoses, fan shroud, and cooler lines for a straightforward swap that returns your engine’s cooling system to efficient operation.

Will this radiator fit my Nissan Armada or Titan?

Yes — the radiator is specifically engineered to match factory mounting points and hose locations for the listed model years. It’s tailored for 5.6L gas and flex-fuel engines where noted, so no cutting, trimming, or adapters are required for compatible vehicles.

• Direct fit for 2005–2015 Nissan Armada 5.6L Gas/Flex
• Direct fit for 2004–2015 Nissan Titan 5.6L Gas/Flex
• Compatible with 2004–2010 INFINITI QX56 and select 2004 Nissan Pathfinder/Armada variants

How does the design improve cooling performance?

Cooling performance is enhanced through optimized airflow and efficient tube/fin geometry. Multi-louvered fins increase surface area and turbulence for faster heat transfer, while flat-flow B-type tubes promote uniform coolant distribution and reduce hotspots.

• Multi-louvered fins for enlarged heat-exchange surface
• Flat-flow B-type tubes for smoother coolant flow
• Thermal expansion cuts to relieve stress from temperature changes

Is this radiator durable and leak-resistant?

The radiator is built from premium aluminum with reinforced headers and precision welds to resist corrosion and leaks. Each unit undergoes leak and pressure testing to help ensure long-term integrity under normal operating conditions.

• Full aluminum construction with anti-corrosion coating
• Deep extrusion header tanks and precision welded joints
• Factory-level pressure and leak testing before shipment

What should I expect during installation and aftercare?

Installation is intended to be straightforward for anyone familiar with radiator replacement: remove the old unit, transfer any necessary fittings, and hook up hoses and cooling lines. After installation, use the correct coolant mix and check for secure hose clamps and proper bleed procedures to avoid air pockets.

• OEM-spec mounting and hose connection points for quick swap
• No modifications required for direct replacement scenarios
• Recommended coolant flush and system bleed after installation

Who is this for: This radiator is for owners and mechanics looking to replace a failing or underperforming radiator on compatible Nissan and INFINITI trucks and SUVs who want an aftermarket part built to OEM dimensions. It suits drivers needing a durable, lightweight aluminum unit that improves cooling efficiency and resists corrosion, and it’s appropriate for professional installers or experienced DIYers comfortable with coolant systems.
