Performance Radiator for Dodge Ram D150 D250 D350 W150 W250 (1979-1993) 3.9L 5.2L 5.9L

All-Aluminum 3-Row Performance Radiator for 1979-1993 Dodge Ram (D/W Series)

What it Does: The 3-row performance aluminum radiator replaces the failure-prone factory copper-brass or plastic-tank core on 1979-1993 Dodge Ram trucks to maximize thermal dissipation and prevent coolant boiling under heavy towing loads.

The Stock Dodge Ram Cooling Degradation

Factory cooling systems in first-generation D/W Series Dodge pickups utilized aging copper-brass cores with lead-soldered joints or crimped tanks prone to thermal fatigue and separation. Over decades of operation, internal mineral scale restricts coolant passages while external fin oxidation cuts heat dissipation. Under sustained hill climbs or heavy hauling with the Chrysler LA 318 (5.2L) or LA 360 (5.9L) V8 platforms, stock radiators suffer rapid heat soak, triggering elevated cylinder-head temperatures, dangerous transmission fluid breakdown, and head gasket failure.

The Engineering Solution

This drop-in performance unit upgrades your cooling system with a 100% TIG-welded, furnace-brazed 3-row core measuring 18.11" x 24.72" x 1.73". Louvered aluminum fins and high-flow core tubes drastically increase cooling surface area over OEM units, keeping operating temperatures stable in high ambient environments. Heavy-gauge aluminum tanks eliminate brittle mechanical seams and blown gaskets entirely. Configured in a classic downflow orientation, it features an integrated internal transmission oil cooler to maintain automatic transmission fluid integrity during severe duty cycles.
