Aluminum Radiator for Jeep Cherokee Wagoneer (1974-1983) 5.9L

High-Efficiency 3-Row Aluminum Radiator for 1974-1983 Jeep Cherokee

Direct-fit thermal upgrade: Replaces tired, clogged factory cooling cores with an all-aluminum 3-row assembly engineered to eliminate engine overheating under heavy trail loads.

The Stock Cherokee Thermal Bottleneck

Factory SJ-platform radiators relied on traditional copper-brass cores joined with solder, which degrade and oxidize over decades of heat cycles. Internal scale buildup narrows the cooling tubes, while ambient fin separation severely impedes heat dissipation. When working the AMC 360 V8 during low-speed rock crawling or sustained highway towing, restricted fluid circulation and minimal airflow quickly cause underhood heat soak, pushing coolant past operating tolerances.

The Engineering Solution

This performance radiator features a high-density 3-row furnace-brazed aluminum core paired with robotic TIG-welded end tanks, eliminating failure-prone epoxy and solder joints. High-grade aluminum alloys optimize thermal conductivity while significantly lowering core weight. The multi-tube architecture expands internal coolant capacity and maximizes primary surface area for improved heat rejection across the fins. Built as a direct bolt-in unit, it aligns with factory core support mountings and standard hose geometry without chassis modification.
