Product details

The RENNTech by CSF radiator features 6.5mm multi-louvered fins. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while improving airflow over the 6mm OE fins. CSF was able to maintain the same tube and fin row count as the OE unit with a larger fin height due to the shorter but more efficient 2-Row B-Tubes. These features improve the core's ability to dissipate heat while being more structurally robust. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The additional cooling capacity is even more valuable for the larger displacement versions of the M120 V12. The 7.1L and 7.3L AMG engines produce over 500 hp, while RENNTech's 7.4L engine found in the SL 74 produces around 570 hp, and their latest 7.6L found in the new SL 76 puts out over 600 hp. All of these engines produce significantly more heat than the 6.0L (394 hp) powerplant. The RENNTech by CSF Radiator was designed and built to handle the heat from all of the R129's V12s. The combination of 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 hard driving conditions. This includes the 90° overflow pipe which is plastic on the OE unit. This pipe is known to crack on the original radiator requiring a full replacement. The All-Aluminum construction removes this weak point. RENNTech is regarded as the premier Mercedes-Benz specialist in North America and the foremost authority in Mercedes tuning. When the original SL600 radiator (129-500-10-03) was discontinued by Mercedes, they turned to the cooling experts at CSF for a solution. This radiator was not only found in the SL600, but also in the SL 72/70/73 AMG versions, as well as the coach built RENNTech SL 74 and SL 76. This radiator was designed to fit exactly like the OE unit, even down to the color scheme to mimic the original as best as possible. While most SL600's and AMG variants aren't known for cooling issues, they can overheat and heatsoak while sitting in traffic or during hard driving in hot environments. The modern 2-Row CSF core gives the cooling system more headroom for adverse conditions. The RENNTech by CSF SL 600 Radiator is an industry inclusive item. It is the only radiator available to replace the OE 129-500-10-03. This is a Plug-and-Play "Drop-in Fit" replacement utilizing the factory shrouds and brackets.
