CSF 90-93 Mercedes 500SL / 94-02 Mercedes SL500 High-Performance Radiator

With over five decades of expertise in radiator manufacturing, CSF stands as a leader in delivering high-performance cooling solutions tailored for the Mercedes 500SL (1990-1993) and SL500 (1994-2002) models. The CSF High-Performance All-Aluminum Radiator is engineered to maintain optimal engine temperatures, ensuring your SL500 operates efficiently whether on the street or the racetrack. Designed for vehicles demanding enhanced cooling capabilities, especially those with high horsepower or used in motorsports, this radiator incorporates advanced technology to provide superior thermal management. At the core of its innovation lies CSF’s exclusive B-Tube Technology, a significant advancement over traditional oval “O” type tubes. Unlike standard tubes, CSF’s B-shaped tubes are precision-formed and seam-brazed, resulting in a structure that is both stronger and lighter. This engineering allows the use of thinner aluminum material without compromising durability, thereby improving cooling efficiency. The B-Tube design increases the heat transfer surface area by approximately 15% compared to conventional tubes, effectively delivering the cooling performance of two smaller tubes within the same spatial constraints. This unique configuration facilitates “dual liquid laminar flow,” optimizing coolant circulation and heat dissipation. Complementing this technology are ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the radiator core. Each fin’s dimensions and arrangement are carefully calculated and validated through rigorous wind-tunnel testing to ensure peak heat rejection performance. Installation is straightforward with the CSF SL500 radiator’s true “drop-in fit” design, requiring no modifications. All brackets are CNC machined and welded for enhanced durability, mirroring original equipment (OE) standards. The inlet and outlet connections are designed to match OE specifications, enabling seamless integration with OEM hoses or aftermarket alternatives. This attention to detail guarantees compatibility with all attaching components including quick-connect hoses, AC condenser, mounting brackets, and fan shroud.
