CSF Aluminum Radiator for H3 Hummer — 2-Row Core with B-Tube Technology Upgrade cooling performance on your H3 Hummer with the CSF all-aluminum radiator engineered for heavy-duty and high-performance use. Built from CSF’s five decades of radiator expertise, this 2-row core delivers reliable temperature control for towing, off-road driving, and daily use. B-Tube Technology: Unique "B"-shaped tubes increase heat transfer surface area by ~15% vs. conventional "O" tubes, enabling dual liquid laminar flow and improved cooling efficiency. Lightweight, durable construction: Brazed seam B-tubes allow thinner, lighter aluminum without sacrificing strength—ideal for rugged on- and off-road conditions. Optimized fin design: Precision multi-louvered fins maximize airflow and heat rejection; fin geometry is application-specific and validated in CSF’s wind-tunnel lab. Direct fit for H3 Hummer: Vehicle-specific dimensions and inlet/outlet placement for straightforward installation and reliable performance. Ideal for enthusiasts: Perfect for off-roaders, overlanders, and anyone who demands improved cooling under load. Replace your stock radiator with a purpose-built CSF unit to reduce operating temperatures, prevent overheating during heavy use, and extend engine life. This CSF aluminum radiator pairs advanced engineering with field-proven durability for the H3 Hummer.
