BMW Radiators

The BMW E28 M5 and E24 M6, two iconic early M cars, have solidified their status as sought-after classics from the 1980s. However, the cooling systems from that era fall short when compared to modern designs, often presenting issues with durability and efficiency. To tackle this problem, CSF and A/C Solutions collaborated to create a High-Performance All-Aluminum Radiator specifically for the E28 and E24, combining superior cooling performance with a precise factory fit.

The original OE radiator featured an aluminum core paired with plastic end tanks—a design notorious among BMW enthusiasts for eventual failures, such as leaks at the seams or cracking plastic tanks caused by years of heat cycling.

CSF's Classic Series Radiator offers significant upgrades over the original design, most notably its advanced all-aluminum construction. Built with TIG-welded, 100% aluminum materials, this radiator provides enhanced strength, durability, and longevity, ensuring it can withstand even the most demanding driving conditions. With a 1-row 31mm aluminum core, CSF's B-tube technology, and nearly twice the number of cooling fins and tubes compared to the OE radiator, the new design delivers exceptional cooling performance. Additionally, its multi-louvered fins are optimized to maximize airflow, ensuring superior thermal efficiency. The radiator installs seamlessly in the factory location, requiring no modifications or cutting.

Another thoughtful upgrade is the addition of a drain plug. Unlike the factory radiator, which lacks this feature, CSF's new design simplifies tasks like coolant flushes or engine removals, making maintenance more convenient for enthusiasts. This small but practical detail further enhances the overall user experience.

1-Row – 31mm Ultra-High-Performance Core

Cooling Tubes with CSF’s Exclusive B-Tube Technology

6.5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact

Maximize cooling efficiency and take your BMW’s performance to the next level with the ECS High Performance Cooling System Bundle—a complete, track-proven upgrade engineered to handle the extreme thermal demands of the G2X B58 platform. Developed by the enthusiasts at ECS Tuning, this system includes both the High Performance Aluminum Radiator and High Performance Aluminum Heat Exchanger, designed to deliver consistent, reliable temperature control in even the most demanding driving conditions.

The factory BMW cooling components just aren’t built for high-performance or track use. Both the OE radiator and heat exchanger feature weak plastic end tanks and undersized single-row cores—common failure points when exposed to elevated heat and pressure. ECS set out to solve these shortcomings with an all-aluminum, dual-row system designed for enthusiasts who demand more from their BMW. ECS engineers started by replacing the fragile plastic end tanks with TIG-welded 6061-T6 aluminum for unmatched durability. Each tank is precision-crafted with CNC-machined billet aluminum hose connections, flanges, and brackets, ensuring direct OE-style fitment with the factory hoses, fan shroud, and accessories—no cutting or modifications required.

Both the radiator and heat exchanger feature high-capacity, dual-row 42mm cores, a massive improvement over the factory’s 34mm and 25mm single-row designs. The result? Faster heat dissipation, lower intake air temperatures, and more consistent performance, whether you’re cruising or carving apexes.
