{"product_id":"mishimoto-2023-toyota-gr-corolla-performance-aluminum-radiator","title":"Mishimoto 2023+ Toyota GR Corolla Performance Aluminum Radiator","description":"The 2023+ Toyota GR Corolla churns out 300 horsepower from just 3 cylinders and 1.6L of displacement. Each cylinder is running at the limit, and your GRC's cooling system has a lot of work to do to keep up. Long battles on the track or sitting in traffic can easily overwhelm the stock cooling system, and some owners have seen oil temps over 260 degrees on track. The stock oil cooler on the GRC is a liquid-to-liquid design that relies on coolant temperatures to maintain safe oil temps. If your radiator can't keep up, it's only a matter of time before your oil can't either. That's why Mishimoto has developed a performance aluminum radiator to keep every aspect of your GR Corolla's engine cool.----This all-aluminum radiator replaces the stock plastic end tank unit with a core that is 51 percent larger. That increase in core volume means your cooling system can hold more coolant and dissipate more heat, placing less stress on the cooling system overall. Inside the core, we've focused on utilizing the entire cooling area with strutted tubes and louvered fins. Strutted tubes allow us to use a single, wider tube, that has greater effective area than multi-row cores. These strutted tubes also significantly improve core rigidity to help prevent leaks from impacts like potholes or running off track. Louvered external fins circulate air throughout the core to transfer more heat. Finally, the included foam shrouding ensures cool air goes through the core, not just around it.----In addition to performance, we've also thought about durability and serviceability. Our radiator features reinforced intercooler mounts, so you can add a larger intercooler (like Mishimoto's) without worrying about the mounts breaking. To help service your new radiator, we've designed an extended drain port with a slotted drain plug, to keep draining mess-free. Of course, this 2023+ GR Corolla performance radiator is also backed by our Mishimoto Lifetime Warranty for a lifetime of performance.\nAluminum radiator engineered for efficient heat dissipation and optimal engine cooling. Precision-fit design ensures easy installation, corrosion resistance, and reliable performance across varied driving conditions.\n\u003cul\u003e\n  \u003cli\u003e51 percent increase in core volume over stock for improved cooling performance\u003c\/li\u003e\n  \u003cli\u003eSingle-row core with strutted tubes utilizes entire core thickness for cooling\u003c\/li\u003e\n  \u003cli\u003eLouvered external fins improve heat transfer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Mishimoto 2023+ Toyota GR Corolla Performance Aluminum Radiator is engineered to enhance the cooling efficiency of your high-performance vehicle. Designed specifically for the 2023 and 2024 Toyota GR Corolla models, this radiator features a 51 percent larger core volume compared to the stock unit, allowing for increased coolant capacity and superior heat dissipation. This upgrade helps maintain optimal engine temperatures during intense driving, whether on the track or in traffic, reducing the risk of overheating and prolonging engine life.\u003cbr\u003eThe core utilizes strutted tubes and louvered fins to maximize heat transfer. Strutted tubes, which are wider than traditional multi-row cores, provide greater effective surface area and improve core rigidity, making the radiator more resistant to impacts such as potholes or off-road conditions. The louvered external fins facilitate more efficient airflow, ensuring hot air is expelled quickly and cooling performance is optimized. An included foam shroud directs airflow through the core, preventing air from bypassing the radiator and further improving cooling performance.\u003cbr\u003eConstructed from durable aluminum, this radiator replaces the stock plastic end tank unit, offering enhanced corrosion resistance and longevity. Reinforced intercooler mounts are incorporated to support larger intercoolers, such as Mishimoto's own models, without compromising structural integrity. For ease of maintenance, the radiator features an extended drain port with a slotted drain plug, making fluid changes cleaner and simpler. Backed by Mishimoto’s lifetime warranty, this radiator provides a reliable solution for drivers seeking to maximize their vehicle’s cooling efficiency while ensuring durability and ease of service.\u003cbr\u003eInstallation is straightforward due to a precision-fit design that aligns perfectly with the OEM mounting points. Whether you're modifying your GR Corolla for performance or looking to improve cooling reliability, this aluminum radiator offers a significant upgrade over stock components, ensuring your engine remains cool under demanding conditions and supporting sustained high-performance driving.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e51 percent increase in core volume over stock for improved cooling performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSingle-row core with strutted tubes utilizes entire core thickness for cooling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLouvered external fins improve heat transfer\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReinforced intercooler mounts support larger intercoolers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExtended drain port with slotted drain plug for mess-free maintenance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrecision-fit design for easy installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCorrosion-resistant aluminum construction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBacked by Mishimoto Lifetime Warranty\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2023 Toyota GR Corolla Circuit Edition\u003cbr\u003e\n2023 Toyota GR Corolla Core\u003cbr\u003e\n2023 Toyota GR Corolla Morizo Edition\u003cbr\u003e\n2024 Toyota GR Corolla Circuit Edition\u003cbr\u003e\n2024 Toyota GR Corolla Core\u003cbr\u003e\n2024 Toyota GR Corolla Premium\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":53603834790161,"sku":"MMRAD-GRC-23","price":638.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/3830\/0689\/files\/cbf6c6de017abd79395bbc606b80aa25.jpg?v=1779966945","url":"https:\/\/shoprenegade.com\/products\/mishimoto-2023-toyota-gr-corolla-performance-aluminum-radiator","provider":"Renegade Speed by Renegade Racing \u0026 Performance","version":"1.0","type":"link"}
