Fockety Adjustable Waterproof Thermostatic Radiator Cap with Temperature Gauge for Universal Cars, Aluminum Alloy + Dark Blue Silicone Rubber + Black (small head 0.9bar).

1. Made of high-quality silicone rubber, providing a good seal, effectively prevents the radiator from leaking. 2. The radiator cap is used to regulate radiator pressure and maintain the water level in the reservoir. 3. Improves radiator pressure and cooling performance while also enhancing the appearance of the engine compartment. 4. Thermostatically controlled radiator cap: once the discharge pressure exceeds 0.9 kg, the radiator cap spring will open, and coolant will flow to the auxiliary radiator for storage. 5. As the water temperature drops, a vacuum forms inside, and the cap will open to draw water from the auxiliary radiator into the reservoir to maintain a balanced water level.
