Mishimoto Performance Aluminum Radiator for 2023-2026 Toyota GR Corolla (1.6L)

Fits 2023-2026 Toyota GR Corolla Circuit Edition, Core, Morizo Edition, Premium, and Premium Plus (1.6L).

The Toyota GR Corolla pushes its 1.6L three-cylinder engine to the limit, generating significant thermal loads during spirited driving and track sessions. Because the GRC utilizes a liquid-to-liquid oil cooler that relies on the engine coolant to regulate oil temperatures, maintaining cooling efficiency is critical. The Mishimoto Performance Aluminum Radiator addresses this by replacing the restrictive stock plastic end tank unit with a robust, all-aluminum design engineered for high-performance use.

This radiator features a 51% increase in core volume over the factory unit, allowing for a higher coolant capacity and superior heat dissipation. The core utilizes strutted tubes for maximum rigidity—essential for resisting leaks caused by chassis flex or track-day debris—and louvered fins to optimize airflow and heat transfer. For added utility, Mishimoto integrated reinforced intercooler mounts to support larger aftermarket upgrades and an extended drain port with a slotted plug for cleaner maintenance.
