The 2023+ Toyota GR Corolla produces 300 horsepower from just 3 cylinders and 1.6L of displacement.
Each cylinder is operating at the limit, and your GRC's cooling system has significant 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 reported oil temps exceeding 260 degrees on track.
The stock oil cooler on the GRC is a liquid-to-liquid design that depends on coolant temperatures to maintain safe oil temps.
If your radiator cannot keep up, it's only a matter of time before your oil cannot either.
That's why Mishimoto has developed a performance aluminum radiator to maintain 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 enhance 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 considered 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 assist in servicing 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.
