STILLEN Replacement Radiator for Nissan Titan, Nissan Armada and Infiniti QX56

Replace your Nissan Titan's old, cracked radiator with a new, efficient STILLEN radiator. Redesigned in 2013, the STILLEN radiator is specially designed to be a drop-in replacement radiator for the 2004-2015 Nissan Titan, 2004-2013 Infiniti QX56 or 2005-2014 Nissan Armada.

Improved Factory Design

The new STILLEN radiator for Nissan Titan are specially designed to hold twice as much coolant as the factory radiators. Like the factory design, the replacement Titan radiator also features a built-in transmission cooler. Plus, they are also designed to improve reliability, airflow, and total cooling, while still allowing for an easy installation. The stronger header tanks will prevent your Nissan Titan radiator from leaking again!

Nissan Titan Radiator with Extra Thick Core

Featuring a 3-row construction with a 2" thick core, the STILLEN Nissan Titan radiator doubles the size and capacity of the factory radiator. This design also allows the heat rejection to be dramatically improved, making your Nissan Titan, Infiniti QX56 or Nissan Armada more efficient and reliable.

100% Aluminum Titan Radiator Tanks

The STILLEN Titan Radiator eliminates the plastic upper and lower tanks included in the factory design, which are prone to cracking. Instead, the upper and lower tanks are made from 100% aluminum. One of the most common complaints we hear is that the Nissan titan radiator cracked. The all aluminum Nissan titan radiator offers better durability and improved performance.

Exceptional Manufacturer's Warranty

STILLEN is so confident in the quality and craftsmanship of this Nissan Titan radiator that it comes with a 3-year manufacturer's limited warranty. This warranty protects against cracking and leaking when used under normal conditions.

Note: Extend the life of your radiator and protect your warranty by using a vacuum bleeder to evacuate air from the cooling system during installation.



About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.

    This radiator is a real work of art. And it's built like a brick outhouse.

    Very nice product. Worth the money. Other than a little trimming on the plastic radiator shroud, the Armada fitment was perfect. Recommended!

    This radiator solved the overheating problems in my 2005 Nissan Titan. I can now use my truck in extreme conditions and towing where I could not before. Great product at a good price!
