Serving as a dedicated reservoir for your engine's cooling system, this coolant recovery tank plays a critical role in maintaining optimal operating conditions. When the pressure of the coolant surpasses the rated threshold of the radiator cap's internal spring, any surplus coolant is safely diverted into the recovery tank to prevent leakage. As the engine cools down post-operation, a vacuum forms within the cooling system—drawing the stored coolant back into the main system to replenish levels and ensure consistent, reliable cooling performance.
