Performance Radiator for Buick Roadmaster (1994-1996) 5.7L Automatic

High-Efficiency 3-Row Aluminum Performance Radiator for 1994-1996 Buick Roadmaster

Direct-Fit Cooling Upgrade: Replaces failure-prone factory plastic-tank units with a heavy-duty, all-aluminum 3-row crossflow heat exchanger designed to stabilize coolant temperatures in high-thermal-load LT1 V8 applications.

The Stock Roadmaster Thermal Breakdown

Factory GM B-body radiators utilize stamped aluminum cores crimped to composite nylon end tanks. Over repeated thermal cycles, the factory rubber tank gaskets harden, micro-fracture, and blow out under standard operating pressures. Furthermore, the single-row factory core struggles to shed heat when the 5.7L LT1 operates under heavy load or extended stop-and-go driving, leading to thermal soak and elevated transmission fluid temperatures.

The Engineering Solution

This drop-in performance unit features aircraft-grade T-6061 aluminum construction with 100% TIG-welded end tanks, eliminating mechanical crimp seals entirely. The high-density 3-row crossflow racing core increases surface contact area and fluid volume for superior heat transfer. It incorporates internal heavy-duty brass transmission and engine oil coolers on dedicated ports, maintaining factory fluid line routing while preventing cross-contamination and overheating.
