What is the method for adding coolant?

The method for adding coolant and its operational steps are as follows: 1. Tighten the radiator drain switch and fill the radiator with coolant until it overflows. 2. Tighten the radiator filler cap. 3. Fill the engine coolant into the reservoir until the liquid level reaches the full level line. 4. Warm up the engine until the thermostat valve opens. 5. Wait for the coolant to cool down. 6. Remove the radiator filler cap and check the coolant level. Relevant information about coolant is as follows: 1. The full name of coolant is antifreeze coolant. It prevents the engine from freezing in winter and cools the engine when it generates high temperatures during operation, ensuring the vehicle can work normally in various environments. 2. The powerful effects of coolant are composed of various chemical components. Coolant is poured from the reservoir. Front-engine family cars generally require about 3-4 liters of coolant, while for mid-engine or rear-engine cars, since they still need a radiator located at the front of the car to dissipate heat for the cooling system, due to the overall layout, these cars require at least twice the amount of coolant compared to front-engine cars.
I'm quite familiar with the coolant refill method because my car often has this issue. First, ensure the engine is completely cooled—never operate when the car is hot; wait overnight or after the car has been cold for several hours. Open the engine hood and locate the coolant expansion tank, usually a transparent plastic container, and clearly identify the maximum and minimum level marks. If the fluid level is below the minimum, prepare the same type of coolant—avoid mixing different brands as it can cause sedimentation or corrosion issues. Slowly unscrew the cap and pour the coolant into the expansion tank gently to prevent air bubbles. After filling, tighten the cap, start the engine, and let it idle for a few minutes. Then turn it off and check if the fluid level stabilizes. If it's low, top it up until it stays in the middle range. Remember to clean any spilled liquid and check for leaks, as leaks could indicate a faulty water pump or hose. Regularly check the antifreeze every six months—don't wait for a warning light. Pay extra attention to the replacement ratio during seasonal changes.
