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. 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. - 2-Row, 42mm Ultra-High-Performance Core - Cooling Tubes with CSF’s Exclusive B-Tube Technology - New 5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact - CNC Machined Mounting Brackets and OEM Style Inlet/Outlet - Pre-plugged 1/8th NPT temperature sensor port on right side tank - Pre-installed foam strips on top and bottom end plates for increased sealing - 100% All Aluminum TIG-Welded Construction - Hand Brushed Satin Finish - True Plug-and-Play “Drop-in Fit” Installation Requires Absolutely No Modifications - Individually Leak and Pressure Tested - 2-Year Limited Warranty
