2023–2024 Toyota GR Corolla
MMRT-GRC-23MWBK
Overview:
The Mishimoto Coolant Expansion Tank is a premium upgrade designed specifically for the 2023 and 2024 Toyota GR Corolla. Engineered as a direct-fit replacement for the stock plastic tank, this all-aluminum expansion tank offers superior durability and enhanced cooling performance. It is ideal for enthusiasts and daily drivers alike who demand reliability and improved thermal management from their vehicle’s cooling system.
By increasing coolant capacity by 40%, the Mishimoto expansion tank helps reduce engine temperatures during spirited driving or track use, promoting consistent performance and longevity. Its robust construction eliminates common issues associated with factory plastic tanks, such as yellowing, cracking, and leaking after repeated heat cycles.
Key Features:
This expansion tank combines thoughtful engineering with high-quality materials to deliver both functional and aesthetic benefits:
- All-aluminum construction resists yellowing, cracking, and leaks over time
- 40% larger coolant capacity compared to the stock tank for improved heat dissipation

The durable finish prevents discoloration and maintains a clean appearance even after extended exposure to engine bay conditions. Internal baffles are strategically placed to keep coolant near the overflow port, preventing air pockets from forming during hard cornering or rapid acceleration. This design ensures consistent coolant flow and system reliability under demanding driving conditions.
Installation & Fitment:
The Mishimoto expansion tank is a direct-fit replacement for the 2023–2024 Toyota GR Corolla, requiring no modifications for installation. It installs using existing mounting points and hoses, making the upgrade straightforward for enthusiasts with basic mechanical skills. The inclusion of an easy-access bleed port further streamlines the bleeding process, allowing for quick removal of trapped air and ensuring optimal cooling system performance.

What does the ETA date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
