How to use HS codes for tariff predictions

Antifreeze Is An Indispensable Part Of Car Maintenance. It can How to use HS codes for tariff predictionsprotect the engine from damage in the cold winter and prevent the engine from overheating. However, if the antifreeze is not added correctly, it will cause damage to the engine. This article will introduce how to add antifreeze correctly to protect your engine. Step 1: Understand the antifreeze required for your vehicle. Different cars use different antifreeze. Before adding antifreeze, you need to check your vehicle's instruction manual to find out which antifreeze is used for the vehicle. Usually, ordinary cars use ethylene glycol antifreeze, while high-end vehicles may need to use propylene glycol antifreeze. If you are not sure which antifreeze to use, please consult a car repair professional.Step 2: Check the color and freezing point of the antifreeze. If you have decided which antifreeze should be used, you need to check its color and freezing point. The antifreeze should be transparent or slightly light green. If the color changes, it means that the antifreeze may have expired or there may be a problem. In addition, the freezing point of antifreeze also needs to meet the local climatic conditions. If you live in a colder climate, make sure that the antifreeze is low enough, otherwise the antifreeze will freeze. Step 3: Prepare to add antifreeze. Before adding antifreeze, you need to make some preparations. First of all, you need to park the vehicle in a flat position and turn off the engine. Secondly, you need to clean up all the dirt and dust. In order to ensure that the antifreeze is added correctly, you need to find the antifreeze tank of the car. It is usually under the hood, and the specific location can be found in the instruction manual.Step 4: Add antifreeze. After preparing to add antifreeze, the next step is the actual addition. First of all, make sure that the antifreeze tank of the car has been cleaned up. Secondly, open the lid of the antifreeze tank and insert the horn of the antifreeze bottle into the mouth of the antifreeze tank. Don't let the antifreeze overflow, otherwise it may burn you. Add the antifreeze until it basically reaches the maximum mark position. You don't need to fill the whole box, because the antifreeze still needs space to expand. After that, you need to add a certain proportion of water according to the type and grade of antifreeze. However, before adding antifreeze, confirm that the quality, concentration and other characteristics of the purified water used meet the requirements. Step 5: Test the ratio of antifreeze and water. After adding antifreeze, you need to test its ratio with water to ensure compliance with the instructions for use. If the proportion of antifreeze is too much, it will affect the heat dissipation effect;If the proportion is too low, the antifreeze ability of the antifreeze cannot be guaranteed. You can use a professional antifreeze detector or a handheld folding ATC detector to test this ratio. Summary: Before the antifreeze enters your car, you need to know in detail the type, color and freezing point of the antifreeze required for your vehicle. In addition, you also need to make sure that the place where you add antifreeze is clean, and pay attention to safety measures when adding antifreeze to avoid scalding yourself. Adding antifreeze correctly can ensure that your engine runs normally in the cold winter, and can also protect the engine from high temperature damage. Before driving, make sure that the engine is stable enough and the temperature is normal.
