Mishimoto Performance Aluminum Radiator Toyota GR Yaris 20+

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 the 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 the radiator can't keep up, it's only a matter of time before the oil can't either. That's why Mishimoto has developed a performance aluminium radiator to keep every aspect of the 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 the cooling system can hold more coolant and dissipate more heat, placing less stress on the cooling system overall. Inside the core, the entire cooling area is utilised through strutted tubes and louvered fins. Strutted tubes make use of a single, wider tube with greater effective area than multi-row cores, while also significantly improving 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. The included foam shrouding ensures cool air goes through the core, not just around it.

Beyond performance, durability and serviceability are built in. Reinforced intercooler mounts allow for a larger intercooler upgrade without any concern about mount failure. An extended drain port with a slotted drain plug makes servicing the radiator clean and mess-free. This 2020+ GR Yaris performance radiator is backed by the Mishimoto Lifetime Warranty for a lifetime of performance.
