Mishimoto 2023+ Toyota GR Corolla Performance Aluminum Radiator – Enhanced Cooling System

Description

The Mishimoto MM RAD-GRC-23 is a high-performance aluminum radiator designed specifically for the 2023 and 2024 Toyota GR Corolla. With a 51 percent increase in core volume compared to the stock unit, this radiator significantly improves cooling efficiency, ensuring your turbocharged engine maintains optimal temperatures during aggressive driving or track sessions. The all-aluminum construction replaces the original plastic end tank design, providing increased durability and resistance to impact damage, which is especially beneficial for spirited driving or off-road use. Inside the core, strutted tubes and louvered fins work together to maximize heat transfer by utilizing the entire cooling surface, effectively dissipating heat generated by the powerful 300-horsepower engine. The strutted tubes also reinforce core rigidity, reducing the risk of leaks from impacts such as potholes or track excursions. External louvered fins promote airflow circulation, further enhancing heat dissipation and keeping oil and coolant temperatures within safe limits. The included foam shrouding directs cool air through the core, preventing hot air recirculation and optimizing cooling performance. Designed with durability in mind, this radiator features reinforced intercooler mounts, allowing for larger intercoolers like Mishimoto’s own without compromising structural integrity. An extended drain port with a slotted drain plug simplifies maintenance and fluid changes, making service straightforward and mess-free. Backed by Mishimoto’s lifetime warranty, this radiator provides a reliable upgrade that supports the demanding performance needs of your GR Corolla, whether on the street or the track.
