Aluminum Radiator for Dodge Dart (1974-1976) 5.2L 5.9L

High-Efficiency 4-Row Aluminum Radiator for 1974-1976 Dodge Dart

Replaces deteriorating factory cooling hardware: Delivers upgraded heat dissipation for high-displacement Mopar small blocks operating under severe thermal loads.

The Stock Dart Cooling Deficiencies

Factory 1970s Chrysler A-body radiators relied on copper-brass cores sealed with lead solder. Over decades, thermal cycling leads to solder bloom, tube calcification, and external fin degradation that drastically cuts fluid flow and heat exchange efficiency. Paired with late-era emissions equipment and lean air-fuel ratios, the stock 5.2L and 5.9L engines suffer from localized hot spots, continuous heat soak during idling, and premature boiling in high-ambient conditions.

The Engineering Solution

This heavy-duty 4-row radiator utilizes aircraft-grade aluminum construction with fully TIG-welded end tanks and a vacuum-brazed tube-and-fin core. Eliminating epoxy seams and restrictive stock tube designs, the expanded multi-core cross-section substantially elevates liquid capacity and surface area contact. The aluminum core maximizes thermal conductivity, allowing higher airflow throughput to rapidly reject BTUs and stabilize engine operating temperatures under sustained acceleration and stop-and-go driving.
