With over fifty years of dedicated expertise in radiator manufacturing, CSF stands as a hallmark of quality and innovation in automotive cooling solutions. The CSF S550 Ford Mustang GT / Bullitt / GT350 / V6 All-Aluminum Radiator exemplifies this legacy, engineered to deliver exceptional cooling performance for your Mustang, whether on the street or the racetrack. This radiator is specifically designed to meet the rigorous demands of high horsepower engines and motorsport applications, ensuring reliable thermal management under the most challenging conditions.
At the core of this radiator’s superior functionality lies the advanced 2-Row core construction incorporating CSF’s exclusive B-Tube Technology. Unlike conventional oval-shaped “O” tubes, CSF’s B-Tubes are meticulously engineered with a unique “B” profile, which is seam-brazed to enhance structural integrity. This innovative design allows the use of thinner, lighter aluminum material without compromising strength, resulting in improved heat dissipation efficiency. The B-Tube configuration increases the heat transfer surface area by approximately 15% compared to traditional tubes, effectively delivering the cooling capacity of two smaller tubes within the same spatial constraints. Additionally, this design facilitates dual liquid laminar flow, optimizing coolant movement and heat exchange.
Complementing the B-Tube core, CSF utilizes ultra-efficient multi-louvered fins, precisely aligned to maximize airflow through the radiator core. Each fin’s dimensions and alignment are carefully calculated and validated through rigorous wind-tunnel testing to ensure optimal heat rejection performance. This meticulous engineering approach guarantees that your Mustang’s engine maintains ideal operating temperatures, enhancing both performance and longevity.
The CSF Mustang radiator features a true “drop-in fit” design, allowing for straightforward installation without any modifications. The radiator’s OE-style brackets are CNC machined and welded to provide exceptional durability and precise fitment. Inlet and outlet connections are engineered to match original equipment specifications, enabling seamless integration with OEM hoses or aftermarket components. This ensures compatibility with all factory attachments, including quick-connect hoses, AC condensers, mounting brackets, and fan shrouds.
