CSF 6th Gen Camaro / 3rd Gen CTS-V High-Performance Aluminum Radiator
Design & Engineering
When initially designing the radiator, there were several key features that CSF knew were important to the Camaro/CTS-V community: Increased performance, improved reliability, and OEM Fit & Finish.
Key Design Features:
20-25% increase in heat transfer efficiency using CSF’s new 5mm Fin & Exclusive B-Tube Technology.
Improved cooling performance supports additional heat generated by high-performance driving, racing, increased boost pressure, and/or aftermarket turbo setups.
TIG-Welded 100% All Aluminum construction offers incredible durability and longevity vs the factory plastic tank design.
Drop-in fit installation using the factory mounting points, fan, and shroud.
CSF vs OEM
The original Camaro LT1/SS/ZL1 and CTS-V radiators from GM feature aluminum cores crimped onto plastic end tanks. While generally accepted as good quality and durable, this design is significantly weaker than the all-aluminum TIG welded design of the CSF Radiators.
The CSF Advantage
The CSF radiators feature the latest 5mm multi-louvered fins. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is 16% larger than the original GM OE radiator. This core volume difference comes from the thicker 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the core’s ability to dissipate heat.
CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. Combined with the new 5mm fins, heat transfer is increased by up to 25% overall. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance.
All Aluminum Construction
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. Like most plastic OE aluminum radiators, the original units are prone to a variety of other issues due to plastic deterioration over time. The plastic from the tanks and hose fittings start to break down after a few years and the bond to the cores generally won’t last more than 10 years.
Built-in Transmission Oil Cooler
The CSF radiator also features a 4-plate transmission oil cooler built into the driver side end tank. It utilizes the OE connections for a seamless installation. It can be left disconnected for LT1 and SS models with a manual transmission. Both the ZL1 and CTS-V require this cooler.
5mm Core Upgrade
CSF always seeks to offer the ultimate cooling solution. The latest 5mm fin technology was introduced at the end of 2023 offers even more heat transfer area and thermal efficiency than CSF’s tried and true 6.5mm fins. Camaro and CTS-V owners are known to push their cars hard and CSF is confident this radiator is ready to take on the most demanding conditions in the world.
Plug and Play Installation
CSF designed these Radiators to easily replace the OEM unit. The Plug-and-Play “Drop-in Fit” installation means all the factory shrouds and brackets will line up and bolt on perfectly. This includes the Engine Oil Cooler on the left-hand side as well as the A/C Condenser on the front.
Why Upgrade?
Both the LT1 and LT4 engine produce a lot of heat, but the LT4 runs especially hot with the supercharger on top. Combine that extra heat with the front mount heat exchanger stacked in front shedding heat from the Charge Air Cooling system and the OE radiator can struggle to keep up. This kind of heat soak is exacerbated when upgrading the Front Mount Heat Exchanger, like the one CSF makes for Dedicated Motorsports (CSF/DMS #8205), from the extra heat shed from the Charge Air System.
