Performance Radiator for Oldsmobile Bravada (2002-2004) 4.2L Automatic

High-Efficiency 3-Row All-Aluminum Performance Radiator for 2002-2004 Oldsmobile Bravada

What it Does: Direct bolt-on cooling upgrade engineered to replace failure-prone factory plastic-tank radiators with a high-capacity 3-row aluminum core and integrated transmission fluid heat exchanger.

The Stock Bravada Cooling Limitations

Factory GMT360 cooling assemblies utilize single-row cores paired with crimped composite nylon end tanks. Repeated thermal expansion cycles cause the factory tank seams and hose necks to degrade, embrittle, and fracture under pressure. Additionally, the undersized stock core is susceptible to heat soak under sustained loads, mountain grades, or towing, leading to elevated coolant temperatures and increased thermal stress across the Atlas inline-six engine block and automatic transmission.

The Engineering Solution

Engineered for maximum thermal dissipation, this direct-fit unit is fabricated entirely from aircraft-grade aluminum and features 100% TIG-welded end tanks to eliminate failure-prone gasket crimps. The heavy-duty 3-row core measures 18.1 in H x 26.75 in W, drastically expanding fluid capacity and surface area for superior heat rejection. An integrated internal transmission oil cooler (M14x1.5 ports) maintains hydraulic fluid within optimal operating temperature windows, preventing transmission fluid breakdown.
