CSF Mercedes AMG GT / GT S / W205 C63 / W166 GLE63 / X166 GLS63 Auxiliary Radiator

The CSF Mercedes AMG GT / GT S / W205 C63 / W166 GLE63 / X166 GLS63 Auxiliary Radiator is a meticulously engineered component designed to enhance the cooling efficiency of high-performance Mercedes-Benz AMG vehicles. Constructed entirely from high-grade aluminum, this auxiliary radiator integrates seamlessly with the existing cooling system to effectively reduce temperatures across critical engine and turbocharger components. This is essential for maintaining optimal performance and reliability, especially under demanding driving conditions. Functioning as a vital part of the cooling architecture, the auxiliary radiator not only lowers engine coolant temperatures but also serves as the heat exchange medium for the air-to-water charge-air coolers associated with the turbocharger system. By reducing intake air temperatures (IATs), it contributes directly to improved combustion efficiency and power delivery. The increased capacity of the CSF auxiliary radiator extends the heat soak threshold, thereby sustaining temperature stability and preventing performance degradation during prolonged or aggressive use. One of the distinguishing features of this CSF auxiliary radiator is the inclusion of a detachable rock guard. This protective element guards against debris accumulation and potential core punctures, a notable improvement over OEM auxiliary radiators which typically lack adequate protection from environmental hazards. This design consideration ensures durability and longevity, reinforcing CSF’s commitment to quality and reliability. For optimal cooling performance, CSF recommends replacing both left and right OEM auxiliary radiators with this product in vehicles originally equipped with dual units. Furthermore, pairing these auxiliary radiators with the CSF Front Mount Heat Exchanger (CSF #8088) maximizes thermal management capabilities, delivering comprehensive temperature control across the vehicle’s cooling system. Product Details Following the success of CSF’s #1 selling Front Mount Heat Exchanger for the W205 Mercedes AMG, the demand for additional Mercedes-Benz cooling solutions prompted the development of a complete lineup of advanced cooling products tailored for AMG models. This auxiliary radiator represents a key component of that expansion, targeting the prevalent heat soak issues experienced by AMG vehicles, particularly in warmer climates. AMG vehicles are known to experience heat soak, which can compromise performance and component longevity. The CSF auxiliary radiator addresses this challenge by significantly improving heat dissipation, thereby enhancing the vehicle’s thermal resilience. This product is engineered to complement the existing cooling system, providing a balanced and efficient temperature management solution. Derived from the industry-leading Front Mount Heat Exchanger technology, the CSF auxiliary radiator features a 2-row high-performance core utilizing proprietary B-Tube technology. This design incorporates ultra-efficient 6.5mm tall fins with a multi-louvered configuration to maximize surface area contact and heat transfer efficiency. The core thickness of approximately 42mm nearly doubles the capacity compared to the OEM 26mm core, enabling superior cooling performance. ⚠ Fitment Notes Due to the increased thickness of the CSF auxiliary radiator (approximately 1 inch or 25mm thicker than the factory unit), vehicles equipped with larger wheels and tires, such as 20″ wheels on C63 models, may require trimming of the rear plastic duct or shroud by approximately 1 inch (25mm) to accommodate the radiator. This modification ensures proper fitment and airflow. Similarly, AMG GT models may necessitate trimming or removal of the rear duct or shroud to facilitate installation.
