Mishimoto Coolant Expansion Tank - Toyota GR Corolla (2023+) - Red

Introducing the Mishimoto Coolant Expansion Tank for the 2023+ Toyota GR Corolla. This direct-fit solution boasts all-aluminum construction that won't yellow, crack, or leak with repeated heat cycles like the stock plastic tank will. Internal baffles prevent air entry during aggressive driving, while a 40-percent increase in coolant capacity improves heat dissipation. The easy-access bleed port simplifies air bleeding, saving you time and frustration. A high-visibility sight glass and stamped cold-fill line allow quick coolant level checks. Choose from micro-wrinkle red or black finishes to match your style. Backed by the Mishimoto Lifetime Warranty, this expansion tank combines performance and aesthetics for a confident driving experience as long as you own your GR Corolla.
