Car Thermostatic Cap Tank Cover Water Temperature Utility Safe 0.9bar 1.1bar 1.3bar Thermost

Function:The cap is d not only to prevent water leakage, but to regulate preure, maintaining the tank water level.With water temperature rising up, the coot starts to expand. Once it exceeds 0.9KG release preure, the cap spring will open up and the coot flow to auxiliary to store.On the conry, 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 into the water tank to maintain the water level bace.Features:1. Improve the preure and cooling performance;2. Modify engine appearance;3. Silicone rubber for good sealing;Specifications:Type: big headMaterial: alloy + silicone rubberColor: dark blue + blackApplication: universalPreure rating: 0.9 Bar/ 1.1 Bar/ 1.3 BarProduct size: 65 x 45mm/2.56 x 1.77" (length x width)Gro weight: 82gWarm 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 tightne of the water tank.
