Radiator 03-09 Dodge Ram 2500 5.9L / 07-09 6.7L

The Northern Radiator for 2003–2009 Dodge Ram 2500 with 5.9L engines and 2007–2009 models with 6.7L engines is a direct-fit replacement designed to meet the cooling demands of heavy-duty diesel and gas powerplants. This aluminum/plastic core radiator measures 27 inches wide by 29.25 inches tall with a 1.625-inch depth, engineered to restore factory cooling capacity in trucks experiencing overheating, leaks, or age-related degradation. The driver-side inlet and passenger-side outlet configuration matches OEM specifications, ensuring seamless installation without adapter hassles.

Aluminum cores dissipate heat more efficiently than traditional brass designs, while the plastic tanks resist corrosion from ethylene glycol coolant and mineral-heavy well water common in rural and industrial settings. At 34 pounds, this radiator carries substantial core mass—a characteristic of heavy-duty cooling systems built to handle sustained high-load conditions. The hybrid aluminum-plastic construction is standard across modern light-duty and medium-duty trucks, balancing weight reduction against thermal performance. Proper coolant circulation requires correct inlet/outlet orientation; this unit's factory configuration eliminates guesswork during swap-out procedures.

Fleet operators, owner-operator truckers, and weekend warriors working their Ram 2500 in towing or off-road conditions benefit most from this replacement. Whether upgrading a truck that's been pushed hard or restoring cooling function to an aging platform, this Northern-branded core delivers consistent thermal management. Fitment spans 2003–2009 gas models and 2007–2009 6.7L diesel variants, so confirm your engine displacement and model year before ordering. Northern Radiator's reputation for quality aftermarket cooling makes this a trusted choice for buyers seeking dependable OEM-equivalent performance without dealership pricing.
