This direct-fit aluminum coolant expansion tank replaces the stock plastic tank on the 2023-2024 Toyota GR Corolla, which can yellow, crack, or leak with repeated heat cycles. All-aluminum construction adds a 40% increase in coolant capacity over stock, while internal baffles keep coolant near the overflow port to prevent air entry during aggressive driving. An easy-access bleed port, high-visibility sight glass, and stamped cold-fill line make level checks and bleeding simple.
