Radiator and Cooling Fan for GMC Jimmy (1995-2005) 4.3L

Heavy-Duty 4-Row Aluminum Radiator & Electric Fan Kit for 1995-2005 GMC Jimmy

What it Does: The 4-Row Aluminum Radiator and Electric Fan Assembly replaces the fragile stock radiator and mechanical fan on the 1995-2005 GMC Jimmy to eliminate engine overheating and increase cooling capacity under heavy load.

The Stock GMC Jimmy Thermal Vulnerability

Factory cooling modules on the second-generation GMT330 platform utilize thin, single-row aluminum cores crimped to molded composite plastic end tanks. Over thousands of heat cycles, these plastic tanks embrittle, leading to stress fractures along the tank seams and seal failure at the core gasket. Additionally, the OEM engine-driven mechanical clutch fan robs horsepower from the Vortec 4300 V6 and fails to move sufficient CFM at low engine speeds, causing rapid heat soak in traffic, steep off-road climbs, or while towing.

The Engineering Solution

Engineered for sustained thermal control, this direct-fit performance kit features an all-aluminum 4-row crossflow core joined to heavy-gauge end tanks via precise, 100% TIG welding—completely removing weak plastic seams from the equation. The brazed tube-and-fin design maximizes primary and secondary surface area for rapid heat rejection. The assembly includes a tailored aluminum shroud that seals against the core to direct airflow through dual 12V electric fans, supplying steady, high-volume CFM across the entire heat exchanger regardless of engine RPM while directly replacing references like DPI1826.
