Mishimoto Toyota GR Yaris Aluminium Radiator (2020+)

Key Features

• Direct fit for 2020+ Toyota GR Yaris
• 51 percent increase in core volume over stock for improved cooling performance
• Single-row core with strutted tubes utilizes entire core thickness for cooling

The 2020+ Toyota GR Yaris churns out 300 horsepower from just 3 cylinders and 1.6L of displacement. Each cylinder is running at the limit, and your GR Yaris' 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 GR Yaris 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 aluminium radiator to keep every aspect of your GR Yaris' engine cool.

This all-aluminium 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 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 2020+ GR Yaris performance radiator is also backed by our Mishimoto Lifetime Warranty for a lifetime of performance.
