HEL Direct Fit Oil Cooler Kit for Toyota GR Corolla (2023-)

The Toyota GR Corolla has been highly anticipated since Toyota set the benchmark with the popular Yaris GR. Featuring an impressive 1.6L 3-cylinder turbocharged engine, a rally-inspired AWD system, and a compact chassis, the Corolla GR has attracted global attention, becoming a familiar sight on roads and race tracks worldwide. Following the success of our direct-fit oil cooler kits for the Ford RS, Toyota GR, and Honda Type R, we knew we had to bring the Corolla GR into the workshop for development. Our goal was simple: to design and manufacture user-friendly, easy-to-install kits that require either no or very little modifications. To ensure perfect fitment, we 3D laser scanned the engine bay, engine, and its ancillaries. After determining the optimal oil cooler position, a custom mounting bracket was designed using the threaded ports on the factory bumper support. We 3D-printed a prototype for fitment testing before manufacturing the final aluminum version. All HEL direct-fit oil cooler brackets are laser cut, precision-folded, and powder-coated in black for a stealthy finish. Positioned directly behind the top grille, the Setrab oil cooler benefits from direct airflow, delivering optimal cooling efficiency. Every HEL oil cooler kit features a high-quality, reliable 25-row oil cooler manufactured by Setrab in Sweden. We have been using Setrab coolers for 10+ years with zero performance or quality issues. Having an oil cooler fail or burst is not something you want to experience, especially in demanding conditions—something we have never seen with Setrab's build quality. We've even had reports of front-end collisions where the Setrab oil cooler was the only component that still worked. Delivered with pre-assembled braided hoses and aluminum fittings, our comprehensive kit has everything required for straightforward installation. Using AN10 high-flow performance hose to deliver and return oil from the external oil cooler, this kit includes one of HEL's popular oil filter sandwich plates, equipped with a built-in thermostat. The thermostat ensures your engine oil flows to the external oil cooler only when the oil reaches the desired temperature (92°C / 198°F). Around 10% of the engine oil circulates through the oil cooler at any given time, ensuring continuous flow that prevents air pockets and safeguards against thermal shock. The surplus oil is channeled back to the engine through the internal bypass system, promoting faster warm-up, providing added protection in cold weather conditions, and eliminating the risk of overcooling. Included with every kit is an easy-to-read installation manual. If you need assistance, our technical support team is always happy to answer any questions.
