Universal Car Thermost Radiator Cap Cover & Water Temp Gauge Meter 1.1Bar

Function: The radiator cap is used not only to prevent radiator water leakage, but to regulate radiator pressure, maintaining the tank water level. With water temperature rising up, the coolant starts to expand. Once it exceeds release pressure, the radiator cap spring will open up and the coolant flow to auxiliary radiator to store. On the contrary, with water temperature decreasing, the volume of water becomes smaller, a vacuum is formed inside the water tank. And at this time the water tank cover also opens and sucks the water from the auxiliary radiator into the water tank to maintain the water level balance. Features: 1. Improve the radiator pressure and cooling performance; 2. Modify engine bay appearance; 3. Silicone rubber for good sealing; Specifications: Material: alloy plus silicone rubber Color: blue plus black Application: universal Pressure rating: 1.1 Bar Product size: 65 x 45mm/2.56 x 1.77" (length x width) Warm prompts: 1. You can accurately know the temperature of the water tank without starting the engine. 2. The silicone plug can enhance heat temperature resistance, enhancing the tightness of the water tank. Included: 1 x Car Radiator Cap Note: 1.Please allow 0.1-0.3cm differences due to manual measurement, thanks. 2.Please understand because of the light irradiation or computer display difference, so I can't guarantee photos and real color is 100 the same.
