CSF GR Corolla & GR Yaris High-Performance All-Aluminum Radiator

The CSF GR Corolla & GR Yaris High-Performance All-Aluminum Radiator represents a significant advancement in cooling technology tailored specifically for the demanding conditions faced by these high-performance vehicles. Building upon the success of the CSF x Jackson Racing High-Performance Stepped Core Intercoolers (CSF #8285/8285B), CSF has responded to the increasing demand for enhanced cooling solutions that match the elevated power outputs and rigorous use cases of GR Corolla and GR Yaris owners.

With over five decades of expertise in radiator manufacturing, CSF delivers a product engineered to maintain optimal engine temperatures under both street and track conditions. The factory cooling systems, while adequate for standard use, often fall short when vehicles are modified or driven aggressively. The CSF High-Performance Radiator addresses these challenges by offering superior heat dissipation capabilities, ensuring reliable performance and protecting your investment in high horsepower builds and motorsports applications.

Advanced Design and Engineering

CSF’s reputation for excellence in Toyota cooling systems is founded on extensive collaboration with customers, race teams, and development partners. This collective knowledge has informed the design of a radiator that not only meets but exceeds the thermal management requirements of the GR Corolla and GR Yaris platforms.

One of the key innovations in this radiator is the proprietary B-Tube Technology. Unlike conventional oval "O" shaped tubes, CSF’s B-Tubes are engineered with a unique "B" shape that is seam-brazed for enhanced structural integrity. This design allows the use of thinner, lighter aluminum material without compromising strength, resulting in approximately 15% greater heat transfer surface area compared to traditional tubes. The increased surface area facilitates dual liquid laminar flow, significantly improving cooling efficiency.

Complementing the B-Tubes are ultra-efficient multi-louvered fins, meticulously aligned to maximize airflow through the core. Each fin’s dimensions and orientation are optimized based on rigorous wind-tunnel testing to ensure maximum heat rejection while maintaining adequate airflow, a critical balance for high-performance cooling.

Superior Core Construction

The radiator features a robust 2-Row, 42mm thick aluminum core, a substantial upgrade from the factory’s single-row, 27mm core. This increased thickness and dual-row configuration enhance fluid capacity and heat dissipation capabilities, crucial for managing the elevated thermal loads generated by turbocharged engines and high-output configurations.

CSF’s commitment to durability is evident in the 100% TIG-welded all-aluminum construction, which surpasses the strength and longevity of the OEM plastic tank and crimped core assembly. The aluminum end tanks are precision CNC machined and welded, providing a resilient structure capable of withstanding the stresses of aggressive driving and racing environments.

OEM Compatibility and Installation

The CSF radiator is designed as a true drop-in replacement, requiring no modifications for installation. Its OE-style inlet and outlet connections are compatible with original equipment manufacturer (OEM) hoses as well as aftermarket options, facilitating straightforward integration into existing cooling systems. The inclusion of pre-installed foam strips on the end plates enhances sealing and directs airflow efficiently through the core, further optimizing cooling performance.

Additionally, the right side tank features a pre-plugged 1/8th NPT port for temperature sensors, enabling precise monitoring of coolant temperatures — a valuable feature for performance tuning and track use.

Intercooler Clearance and Cross-Model Compatibility

Recognizing the spatial constraints posed by larger diameter intercooler piping, particularly from the CSF x Jackson Racing Intercooler and similar aftermarket units, CSF has engineered the end tanks of this radiator to provide additional clearance without compromising volume or flow. This thoughtful design consideration ensures compatibility with a variety of high-performance intercooler setups.

Furthermore, the radiator is uniquely cross-compatible with both the GR Corolla and GR Yaris models, despite differences in the factory units. This versatility simplifies inventory management for dealers and distributors, as a single part number services both vehicle applications.
