CSF High-Performance Radiator | 2023+ Toyota GR Corolla / 2020+ Toyota GR Yaris (7233)

CSF GR Corolla & GR Yaris High-Performance Radiator

CSF is well known for making the best Toyota cooling systems in the world. With years of feedback from Customers, Race Teams, and Development Partners, CSF has the more experience with Toyota cooling systems than any other company in the world.

For the GR Corolla & GR Yaris CSF was able to design the ideal High-Performance replacement. The CSF radiator features the latest 5mm fin technology. These fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow. The core is much larger than the factory featuring 2-Row 42mm aluminum core. This both increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSFs 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.

With more and more people pushing the limits of the GR Corolla / GR Yaris, the factory radiator has started showing its limitations. Bigger turbos cranking out more power create a lot more heat that needs to be dissipated. Furthermore, the intercooler is mounted directly in front of the radiator, so all the heat shed by that system runs through it. In racing applications this can be detrimental to engine coolant temperatures and risk sending your GR Corolla / GR Yaris into limp mode.

The original OE radiator from Toyota is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, there is always room for improvement. The 5mm fins on the OE radiator made the system fairly efficient for a factory unit. The core itself is one of the biggest limiting factors at only 27mm thick and a single cooling row.
