Aluminum Radiator for Dodge Dart (1970-1972) 5.2L 5.6L 5.9L

High-Efficiency 3-Row Aluminum Radiator for 1970-1972 Dodge Dart

What it Does: Replaces degrading factory copper-brass units with an all-aluminum 3-row cooling assembly to eliminate overheating and stabilize coolant temperatures under hard acceleration.

The Stock Dart Cooling Deficiencies

Factory 1970–1972 Dart cooling assemblies relied on narrow copper-brass cores sealed with lead solder. Over decades of heat cycling, these vintage units suffer from internal tube scaling, solder bloom, and fin separation, drastically reducing heat rejection. Under heavy load or prolonged idling, the stock capacity quickly heat-soaks, causing elevated cylinder head temperatures, detonation risk, and boil-overs on high-compression small-block builds.

The Engineering Solution

This replacement radiator is built with a high-density, vacuum-brazed 3-row aluminum core matched to heavy-duty, TIG-welded end tanks. Eliminating failure-prone epoxy and solder joints, the aircraft-grade aluminum alloy delivers superior thermal conductivity and withstands higher system pressures. The optimized tube-to-fin pitch maximizes air-surface contact across the core, lowering return coolant temperatures to protect your engine under heavy load.
