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.
Engine coolant reservoir designed to store and regulate excess coolant for proper system operation. Durable construction resists heat and pressure, helping prevent leaks and maintain optimal temperature.
