CSF Mercedes AMG GT R / GT C High-Performance Auxiliary Radiator

The CSF Mercedes AMG GT R / GT C High-Performance Auxiliary Radiator represents a significant advancement in automotive cooling technology, engineered to meet the rigorous demands of high-performance driving and professional racing environments. Designed as a critical component within the vehicle’s overall cooling system, this auxiliary radiator enhances thermal management by effectively reducing engine water temperatures and optimizing charge-air cooling for turbocharged systems.

By integrating seamlessly with the existing cooling infrastructure, the auxiliary radiator serves a dual purpose. Firstly, it lowers engine water temperatures, thereby preventing overheating and maintaining consistent engine performance under strenuous conditions. Secondly, it functions as the heat exchange medium for the air-to-water charge-air coolers, which are essential in reducing intake air temperatures (IATs). Lower IATs contribute directly to improved combustion efficiency and power output, which are vital for the turbocharged 4.0L V8 engines powering the Mercedes AMG GT series.

The design of the CSF auxiliary radiator emphasizes increased capacity and durability. Featuring approximately double the capacity of the original equipment manufacturer (OEM) units—specifically, a 42mm core thickness compared to the OEM’s 26mm—this radiator extends the heat soak threshold, ensuring the cooling system remains effective even during extended high-load operation. This enhancement is particularly important for track use or aggressive street driving where thermal loads are consistently elevated.

Constructed from 100% all-aluminum material with TIG-welded joints, the radiator offers exceptional strength and corrosion resistance, ensuring long-term reliability. The core incorporates CSF’s proprietary B-Tube technology, which, combined with ultra-efficient 6.5mm tall fins and a multi-louvered design, maximizes surface area contact for superior heat dissipation. This meticulous engineering results in a highly efficient cooling solution that outperforms standard auxiliary radiators.

Installation is straightforward due to the true “drop-in fit” design, which requires no modifications to the vehicle. CNC-machined mounting brackets and OEM-style “quick connect” inlet/outlet fittings facilitate a seamless replacement process, preserving the integrity of the original assembly. Additionally, the radiator includes a detachable black rock guard that protects against debris accumulation and potential core punctures—an improvement over OEM auxiliary radiators that typically lack such protective features.

Key Features

• 2-Row High-Performance Core Featuring CSF's B-Tube Technology
• Core with Ultra Efficient 6.5mm Tall Fins and Multi-Louvered Design for Maximum Surface Area Contact
• Approximately Double the Capacity of OEM Units (42mm Core vs. OEM 26mm Core)
• 100% All-Aluminum TIG-Welded Construction for Enhanced Durability
• True Drop-In Fit with CNC Machined Mounting Brackets and OEM Style Quick Connect Inlet/Outlet
• 1 Hour Mirror Finish Hand Polish and Detachable Rock Guard (Black)
• Multi-Fit Compatibility for Both Left & Right Side Installation (Sold Individually)
• Individually Leak and Pressure Tested for Quality Assurance
• High-Performance Upgrade Suitable for Professional Racing, Street Performance, or OEM Replacement
• 2 Year Limited Warranty Ensuring Product Reliability

For optimal cooling performance, CSF recommends replacing both left and right OEM auxiliary radiators with this high-capacity upgrade on vehicles originally equipped with dual units. Furthermore, pairing these auxiliary radiators with the CSF Front Mount Heat Exchanger (CSF #8088) enhances the overall cooling system efficiency, providing superior thermal management for demanding driving conditions.
