BMW Radiators

The cooling system is a weak point on any E46. Many cars develop issues in as few as 50,000 miles.

Overheating an inline 6 engine almost always results in large repair bill, and sometimes a warped cylinder head.

Replace yours with a high-quality OEM Nissens radiator to prevent further issues and potential overheating.

For enhanced cooling during intense performance, certain BMW 335i and 340i models feature an extra radiator positioned within the front right wheel well. Unfortunately, this radiator often suffers damage from rocks, debris, and other road hazards.

Fortunately, BMW offers brand-new replacements for this part. If you've observed coolant leaks near the front bumper or experienced unexplained coolant loss, it's advisable to inspect your remote radiator for leaks and consider replacing it as needed.

CSF is one of the premier cooling product specialists available on the market thanks to designs such as their High Performance Aluminum Radiators. Using a single pass designed core, this radiator gives you all the cooling you could ever need. Paired with these radiators are CNC machined brackets and corrosion resistant hardware that allow final installation to have a same as stock fitment! This enables you to have much higher cooling without having to cut away any metal or delete any important components just for the sake of lower coolant temperatures. 

Features:

• Two-row 42mm dual core with "B-Tube" technology
• CNC machined mounting brackets
• All needed hardware included
• Hand polished aluminum with a mirror-like finish
• Stock fitment prevents modification to engine bay

Fits the following BMWs:

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

CNC Machined Mounting Brackets and OEM Style Inlet/Outlet
