Aluminum Radiator for RAM 4500 (2010-2012) 6.7L

Heavy-Duty Direct-Fit Aluminum Radiator for 2010-2012 RAM 4500

What it Does: Upgrades the factory cooling circuit to a robust 3-row all-aluminum design engineered to manage severe thermal loads and prevent overheating under continuous commercial payload and towing conditions.

The Stock 4500 Plastic Tank Degradation

The OEM cooling assembly relies on crimped plastic end tanks bonded to an aluminum core via rubber gaskets. Under sustained commercial operation, the 6.7L Cummins generates massive thermal cycles and continuous exhaust gas recirculation (EGR) heat loads. Over time, high cooling system pressures and vibration fatigue the crimped seams, leading to brittle plastic cracking, gasket blowout, and catastrophic coolant loss under load.

The Engineering Solution

This replacement unit is constructed entirely from high-grade AA5052 aluminum, utilizing precision TIG-welded end tanks that permanently eliminate mechanical crimp seams. The 3-row core measures 1.73 inches in thickness, incorporating high-density fin architecture to maximize heat transfer surface area and optimize coolant dwell time. Engineered for direct bolt-in fitment, it drops into factory mounting locations while integrating standard 1.77-inch inlet and outlet connections.
