Improve radiator pressure and cooling performance while changing the appearance of the engine compartment. 4. Thermostatic radiator cap: once the discharge pressure exceeds 0.9 kg, the radiator cap spring will open and coolant will flow into the auxiliary radiator for storage. 5. As the water temperature decreases, a vacuum forms inside; the cap will open to draw water from the auxiliary radiator back into the reservoir to maintain a balanced water level.
