Increase the boiling point.
Suppress the resulting blisters.
The water tank cover with a water temperature gauge for off-road motorcycles, as well as the car,can always know the temperature of the coolant, and is no longer afraid of the water temperature being too high to damage the engine.
All water tanks are universal.
Not only is it to prevent the water tank from leaking, but the bigger role is to adjust the pressure balance of the water tank and keep the water level of the water tank balanced.
As the water temperature rises, the cooling water begins to expand. Once the pressure relief value (0.9KG) exceeds the pressure reserve, the spring will open and the cooling water will flow to the tank to store the water.
On the contrary, the water temperature decreases, the volume of the water becomes smaller, and a vacuum is formed inside the water tank.
At this time, the water tank cover also opens to suck the water of the auxiliary kettle back into the water tank to maintain the water level balance.
