The 6th Gen Chevy Camaro and 3rd Gen Cadillac CTS-V are impressive performance vehicles. GM did an amazing job in the design and engineering of both and they've been a big hit among enthusiasts. However, both cars suffer from severe heat soak on track or when heavily modified.
While this might not be an issue for casual owners, it is incredibly frustrating to most enthusiasts. Due to this heat soak issue, the Camaro/CTS-V will go into limp mode when you need power the most. CSF worked with LT1/LT4 experts at Griffin Motorsport and Chamberlain Speed to design a High-Performance Radiator to help remedy this issue.
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.
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.

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.
