Heavy-Duty 3-Row Aluminum Performance Radiator for 1994-1996 Cadillac Fleetwood
What it Does: Direct bolt-on cooling upgrade engineered to replace failure-prone OEM plastic-tank radiators, providing enhanced thermal dissipation for the 5.7L LT1 powertrain under sustained thermal load.
The Stock Fleetwood Cooling Deficiencies
Factory GM D-body radiators rely on crimped plastic end tanks bonded to a single-row core with rubber sealing gaskets. Over continuous heat cycles, these polymer tanks embrittle, crack at the upper inlet and lower outlet necks, and leak under normal 15-18 PSI cooling system pressure. Furthermore, the reverse-flow cooling architecture of the 5.7L LT1 demands aggressive heat rejection, which the narrow factory core struggles to deliver during heavy towing or prolonged stop-and-go driving, leading to fluid breakdown and elevated cylinder head temperatures.
The Engineering Solution
This high-efficiency crossflow performance radiator is built with 100% TIG-welded aircraft-grade aluminum, replacing crack-prone composite end tanks with structural, leak-tested alloy. The 3-row racing core measures 30-1/2 inches wide by 17 inches high, significantly increasing fluid surface area and maximizing air-to-coolant thermal transfer. It integrates internal transmission and engine oil cooler circuits to maintain critical drivetrain fluid viscosities under heavy load without requiring external line rerouting.
