About Northern Radiator

For over 40 years, Northern Radiator has been one of North America's most trusted names in automotive and heavy-duty heating and cooling components. Headquartered in Willmar, Minnesota, Northern operates a primary manufacturing and distribution facility alongside a network of 18 regional distribution centers spread across the United States — a logistics backbone that ensures fast order turnaround and broad product availability no matter where you are.

Northern's reputation was built on a simple philosophy: engineer products that hold up under real-world conditions. Whether you're maintaining a daily-driver pickup, restoring a classic muscle car, keeping agricultural equipment running through harvest season, or pushing a race car to its limits on the track, Northern has engineered a solution. The brand serves automotive, agricultural, truck, industrial, and racing markets, making it one of the most versatile thermal management suppliers in the aftermarket.

Cooling System Expertise

At the heart of Northern's catalog are its radiators — the product category that put the brand on the map. Northern engineers and manufactures hundreds of aluminum high-performance radiator designs specifically for race cars, hot rods, and muscle cars, alongside a comprehensive lineup of OE-replacement units for everyday vehicles. Precise fitment, durable construction, and improved thermal efficiency are hallmarks of every Northern radiator.

Keeping the entire cooling circuit running smoothly goes beyond the radiator itself. Northern also produces engine cooling fan shrouds that direct airflow efficiently through the radiator core, and auxiliary engine cooling fan assemblies that provide supplemental airflow exactly where it's needed — critical for towing applications, high-performance builds, and vehicles operating in extreme heat conditions.

Heating Solutions for Every Application

Northern's expertise isn't limited to keeping engines cool. The brand's HVAC heater assemblies are a go-to choice for trucks, hot rods, work vehicles, and specialty equipment. From compact 12-volt auxiliary units ideal for classic car restorations to high-output assemblies suited for heavy commercial vehicles, Northern heaters are known for their heavy-duty powder-coated finishes, efficient blower motor designs, and straightforward installation.

Specialty Repair Products

Rounding out the lineup, Northern also offers fuel tank repair kits — a practical addition to their catalog of maintenance solutions for working vehicles and equipment. These kits reflect Northern's broader commitment to keeping vehicles operational with reliable, easy-to-use repair products.

Quality as a Way of Life

Northern Radiator's long-standing presence in the aftermarket is no accident. The brand backs its products with sophisticated engineering, rigorous quality standards, and a distribution network designed for speed. Whether you're a professional technician, a performance enthusiast, or a fleet manager, Northern delivers the thermal management products you need to keep any vehicle running at its best.
