Product Description
Given the age of the E28 M5 and E24 M6, it is definitely worthwhile to upgrade the cooling system. The factory systems from the 80s were fine at the time, but cooling technology has come a long way since then. So if you're looking for the best possible cooling system, then look no further than the new CSF BMW E28 M5 / E24 M6 High-Performance All-Aluminum Radiator.
CSF has over 5 decades of experience in manufacturing radiators. So when it comes to keeping your engine cool and your E28 M5 or E24 M6 running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high-horsepower builds as well as race vehicles, which need added cooling performance in motorsports environments. This radiator features a 1-row, 31mm core with CSF's exclusive B-Tube Technology: Unlike a regular oval-shaped "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"-shaped tubes that are welded. The design (inlet in the middle of the seam-brazed tube) increases the surface area for heat transfer 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 E28 M5 & E24 M6 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 ones. Trust the cooling experts at CSF for the best-performing, highest-quality, and most reliable radiators.
Design & Engineering
CSF teamed up with A/C Solutions to develop this new radiator. Their founder, Austin Caccavo, is a longtime E28 enthusiast. He started the company after updating the A/C system on his own E28. The relationship began with CSF manufacturing A/C condensers for their upgrade and conversion kits, which eventually led to Austin asking if CSF would make a high-performance radiator for the E28 M5. Austin and his team worked closely with CSF's engineering team to develop this radiator for perfect fitment, optimal performance, and all the features E28/E24 owners could hope for.
The original OE radiator from BMW is an aluminum core with a plastic tank design. While this design is very common for OE radiators, heat exchanger technology has progressed significantly over the decades since these cars were released. Older high-performance vehicles require the best possible cooling systems and can greatly benefit from improved cooling efficiency. Anyone who has restored/updated a classic car knows the value of having updated parts that are as efficient as possible.
The CSF radiator features a 1-Row 31mm aluminum core that improves heat dissipation. CSF's exclusive B-Tube technology increases the heat transfer by approximately 15% over regular oval welded tubes. With approximately 35% more cooling fins, the CSF Radiator will outperform the OEM unit by a significant margin. The super-efficient multi-louvered fins also maximize airflow through the core, ensuring the best possible performance. The radiator mounts in the factory location and requires no modifications or cutting.
The TIG-welded 100% all-aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to demanding driving conditions.
It has a drain plug.
Those familiar with the radiator on the E28 M5 and E24 M6 know that the factory radiator does not come with a drain plug. While this isn't the end of the world, it's definitely a nice thing to have if you're going to do a coolant flush, pull the engine out, etc.
