CSF 7061 Radiator for HUMMER H3 / H3T (combo model - 3.5L/3.7L/5.3L)

Part number7061

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to ensuring your H3 Hummer's engine cooling and optimal performance. This all-aluminum CSF Heavy-Duty/High-Performance Radiator is designed for both on-road and off-road use, making it an essential upgrade for off-road enthusiasts, overland travelers, and adventurers. This radiator features a 2-row core with CSF's exclusive B-Tube Technology. Unlike conventional "O" style oval radiator tubes, CSF utilizes specially engineered "B" shaped tubes. These B-tubes are meticulously formed and then seam-soldered for a leak-proof seal. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional "O" style welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes' heat exchange by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes versus one larger tube within the same space criteria. With B-tubes, "dual-core laminar flow" can be achieved. CSF also employs highly efficient louvered fins that are precisely and accurately aligned to maximize airflow through the radiator core. Fin characteristics are carefully measured and calculated for each application and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

The CSF H3 Hummer Radiator is a true "drop-in fit" design, requiring no modifications for installation. OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet connections are designed to match original equipment specifications, allowing you to use OEM or aftermarket hoses. Whether you're off-roading, towing, or simply driving your vehicle, trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
