• Replaces OEM numbers including 214607S000 and 214609FD0A

How does this radiator handle heavy-duty driving and towing?

The radiator uses multi-louvered aluminum fins and reinforced tubes to increase heat transfer and structural durability under load. Its design helps maintain engine temperature stability during towing, steep grades, and hot-weather operation.

• High-density fins for faster heat dissipation
• Reinforced tube-to-header joints resist pressure and vibration
• Deep-extrusion headers enhance strength where it matters
• Optimized flow paths for consistent coolant circulation

What materials and construction features improve longevity?

Constructed from robust aluminum with B-type tubes and central reinforcements, this radiator reduces the risk of leaks and premature failure caused by thermal cycling and road vibration. Quality welding and reinforced connections add resilience for long-term service life.

• Heavy-duty aluminum core and headers
• Reinforced tube central supports to resist deformation
• Durable joints to withstand pressure spikes
• Corrosion-resistant surfaces for extended durability

Are there any installation tips or fitment checks I should know?

Because it's a direct OE-style replacement, installation follows the factory layout, but verifying fitment first prevents surprises. Use the seller's fitment confirmation tool or supply your VIN for precise matching; inspect mounting brackets and hose orientations before final tightening.

• Confirm model year and engine size (5.6L V8) before purchase
• Use fitment tool or VIN to validate compatibility
• Check hose clamps, fan shroud, and transmission cooler connections during install
• Bleed the cooling system per manufacturer procedure after installation

Who is this for? Drivers and technicians replacing a failed or underperforming radiator on 5.6L Nissan Armada, Titan, or INFINITI QX56 vehicles who want a durable, factory-style aluminum replacement. This radiator suits owners who tow or frequently operate in high-load or high-temperature conditions and need a unit that restores proper cooling capacity while matching OEM fitment and service points.
