The Hummer H3 Radiator by CSF is an all-aluminum, dual-core radiator featuring advanced B-Tube Technology, designed for models from 2006 to 2010. This high-performance radiator excels both on and off-road, making it an ideal upgrade for off-road enthusiasts, overlanders, and adventure seekers who want to ensure their engine remains cool and performs optimally.

Manufactured with CSF's renowned expertise, this radiator provides a significant improvement in cooling efficiency compared to standard radiator tubes. The CSF H3 radiator leverages an innovative design where "B-tubes" increase the heat transfer surface area by approximately 15% over regular tubes. This design enables efficient dual liquid laminar flow, lighter material usage, and enhanced durability. The radiator's multi-louvered fins are precisely aligned for optimized airflow through each core, maximizing heat dissipation. With its "drop-in fit" design, it requires no modifications for installation, providing easy integration with your OEM components.
