The GR Corolla has become one of the most popular hot hatches on the market, especial among track enthusiasts. Its 1.6L three-cylinder turbo motor shared with the GR Yaris is an engineering marvel and offers plenty of room for growth. Pairing that with the all-wheel-drive system, great suspension, and stiff chassis, you have a near perfect track machine.
After the massive success of the CSF x Jackson Racing High-Performance Stepped Core Intercoolers (CSF #8285/8285B), CSF has received a lot of requests for a performance radiator. With more owners turning the power up and pushing the GR Corolla & GR Yaris harder, the factory systems struggle to keep up. CSF is here to help you never lose your cool with the new GR Corolla / GR Yaris High-Performance All-Aluminum Radiator.
CSF vs OEM
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.
With data collected by development partners and race teams, 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. CSF’s 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.

The 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. The right side tank includes a pre-plugged 1/8th NPT temperature sensor port for those looking for more accurate coolant temperature readings. Pre-installed foam strips on top and bottom end plates improve sealing for better airflow over the radiator. The CSF radiator mounts in the factory location and requires no modifications or cutting.

Intercooler Clearance
TheCSF x Jackson Racing Intercoolerand some other aftermarket intercoolers utilize piping/hoses that are larger in diameter than the factory units. These larger intercooler pipes may have clearance issues with other aftermarket radiators. CSF carefully designed the end tanks on the #7233 with additional clearance for the CSF x Jackson Racing Intercooler while maintaining optimal volume and flow.
GR Corolla & GR Yaris Cross Compatibility
The engineering team at CSF spent extra time developing a radiator that could fit both the GR Corolla and GR Yaris. The factory radiator are very similar, but not interchangeable. This cross compatibility is a huge advantage for Dealers and Distributors as they only have to stock one part for both applications.
