The steps of adding water to Haval f7 water tank are as follows: 1, open the hood and find the coolant storage tank; 2. After opening, it can be directly replenished to the appropriate liquid level. What is put into the water tank must be special water for the water tank or qualified antifreeze. When water is scarce, tap water can be added to temporarily replenish the liquid level, but it cannot completely replace the coolant. The special water or coolant for the water tank is antifreeze, and the tap water can't meet the requirements. The service life of the coolant in the tank is 2 years, and it should be replaced after 2 years. Automobile water tank, also known as radiator, uses water as heat carrier to transfer heat, and then dissipates heat through convection of large area fins to maintain the appropriate working temperature of the engine. When the engine water temperature is high, the pump repeatedly circulates water to reduce the engine temperature. () The structure of the water tank is hollow copper pipe. High-temperature water enters the water tank and circulates to the cylinder wall of the engine through air cooling) to achieve the purpose of protecting the engine. If the water temperature is too low in winter, the water circulation should be stopped to avoid the engine temperature being too low. Automobile water tank is the main component of automobile cooling system, and its function is to dissipate heat. The cooling water absorbs heat through the water jacket, flows to the radiator, dissipates heat, and then returns to the water jacket for circulation to realize temperature control.
