Radiator for Hyundai Genesis (2009-2010) 3.8L

Direct-Fit Heavy-Duty Radiator for 2009-2010 Hyundai Genesis

What it Does: The replacement radiator restores closed-loop thermal heat rejection on the 2009-2010 Hyundai Genesis to prevent coolant boil-over and engine overheating under severe operating conditions.

The Stock Hyundai Genesis Thermal Degradation and Plastic End Tank Fatigue

Factory radiators installed in the BH chassis Hyundai Genesis suffer from material breakdown due to repeated thermal expansion and contraction cycles. The OEM glass-filled nylon end tanks become brittle over time, leading to micro-cracks along the inlet neck and failure of the crimped core-to-tank gasket channel. This deterioration causes coolant pressure loss, exposing the 3.8L Lambda II (G6DA) V6 to heat soak, blown head gaskets, and cylinder head distortion.

The Engineering Solution

This cooling assembly is engineered to exceed standard heat dissipation requirements while maintaining factory mounting points. Featuring high-efficiency aluminum tube-and-fin core geometry, the unit increases fluid-to-air thermal exchange surface area. The high-density polymer end tanks resist glycol acidity and pressure surges, while the integrated internal brass transmission cooler fittings maintain structural integrity under load. Designed around OEM reference DPI 13059, it drops into the factory core support with no modifications to hoses or brackets.
