Our heavy duty Radiator is designed specifically for the LS engine. We use a double pass design for maximum cooling and proper positioning of the outlets. The outlets are also sized to fit the LS engine.
Each radiator is TIG welded and contains no epoxy. A steam port is added to the side tank to accommodate the LS steam vent.
Our radiator accepts the original JK fan assembly, a/c condenser and mounting hardware. Slight modifications to the fan assembly are required for a perfect fit.
This radiator is highly recommended for any engine larger than 5.3 liters. We find the 5.3 liter engine runs fine with the stock JK radiator; however, in hot climates or slow crawling it is good insurance against overheating.
