Mishimoto Coolant Expansion Tank for 2023-2024 Toyota GR Corolla - Micro-Wrinkle Black (MMRT-GRC-23MWBK)

Fits 2023-2024 Toyota GR Corolla Circuit Edition, Core, and Morizo Edition.

Standard plastic coolant expansion tanks are prone to yellowing, cracking, and eventual failure due to constant heat cycling. This Mishimoto performance expansion tank provides a durable, all-aluminum solution for your G16E-GTS powered GR Corolla. Beyond its robust construction, this tank features a 40-percent increase in coolant capacity over the OE unit, significantly improving the system's thermal mass and heat dissipation capabilities.

Engineered for aggressive driving and track use, the internal baffles keep coolant positioned near the overflow port, preventing air from entering the cooling system during high-G cornering. The integrated high-visibility sight glass and stamped cold-fill line allow for rapid fluid level checks, while the easy-access bleed port simplifies maintenance. Finished in a micro-wrinkle black powder coat, this tank offers a sleek, professional appearance backed by the Mishimoto Lifetime Warranty.
