A coolant expansion tank is part of the engine cooling system and is designed to compensate for coolant expansion when the engine heats up while maintaining stable system pressure. It is connected to the radiator and hoses, supporting proper coolant circulation and preventing air pockets.

A functioning expansion tank helps maintain engine temperature and prevents coolant leaks or pressure loss. Over time the tank may crack, warp from heat, or lose sealing at the cap. Symptoms of failure include coolant leakage, overheating, coolant smell, or dropping fluid level.
