The expansion tank is a vital component of a vehicle’s cooling system, designed to accommodate the expansion of coolant as it heats up during engine operation. Typically made of durable, heat-resistant plastic or aluminum, it maintains optimal pressure levels in the cooling system, prevents coolant loss through overflow, and serves as a reservoir for replenishing fluid. Equipped with a pressure relief cap, it releases excess pressure to avoid system damage and also helps bleed air from the cooling circuit, ensuring efficient heat dissipation and protecting the engine from overheating. Widely used in passenger cars, trucks, and commercial vehicles, this compact part plays a critical role in maintaining stable engine performance under varying operating conditions.
