Mishimoto Aluminum Coolant Expansion Tank for 2023+ Toyota GR Corolla (MMRT-GRC-23)

Introducing the Mishimoto Coolant Expansion Tank for the 2023+ Toyota GR Corolla, a direct-fit upgrade made from durable all-aluminum construction that resists yellowing, cracking, or leaking from heat cycles, unlike the stock plastic tank. Internal baffles prevent air entry during aggressive driving, while a 40% increase in coolant capacity enhances heat dissipation. The easy-access bleed port makes air bleeding hassle-free, and a high-visibility sight glass with a stamped cold-fill line allows for quick coolant level checks. Available in micro-wrinkle red or black finishes, this tank not only boosts performance but also adds style to your engine bay. Backed by the Mishimoto Lifetime Warranty, it ensures long-lasting reliability and aesthetics for your GR Corolla.
