Thermal Radiator Cap, Thermostatic Gauge Cap, Thermostatic Radiator Cover, Easy Installation, Aluminum Alloy, Silicone Rubber.

1. The use of silicone rubber and a good seal can effectively prevent the radiator from leaking. 2. The radiator cap serves to regulate radiator pressure and maintain the water level in the reservoir. 3. 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 opens and coolant flows to the auxiliary radiator for storage. 5. As the water temperature decreases, a vacuum forms inside, and the cap opens to draw water from the auxiliary radiator into the reservoir to maintain a balanced water level.
