Chevy Colorado 5.3L / GMC Canyon 5.3L / Hummer H3 All-Aluminum Radiator

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your H3 Hummer running at its best a CSF Heavy-Duty/High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on and off-road a heavy-duty performance radiator is a must-have for off-roaders overlanders and adventurers.

This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes, producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra-efficient multi-louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application and tested for maximum heat rejection efficiency in our wind tunnel lab.

The CSF H3 Hummer radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket. Whether you are off-roading towing or just casually driving trust the cooling experts at CSF for the best-performing highest-quality and most reliable radiators.
