What is the method for adding coolant?
2 Answers
Coolant filling method is: 1. Open the front hood and tighten the radiator drain switch; 2. Pour coolant into the radiator until it overflows; 3. Tighten the radiator filler cap; 4. Fill the engine coolant into the reservoir. The functions of coolant are: 1. Prevent corrosion of metal parts and aging of rubber components; 2. Prevent freezing and cracking of the radiator or engine cylinder block due to coolant freezing during parking in cold seasons; 3. Prevent engine water temperature from becoming too high, ensuring the engine operates at normal working temperature; 4. Reduce scale formation to avoid clogging circulation pipes and affecting the cooling system's heat dissipation function; 5. Provide lubrication for the water pump thermostat and other components.
I think adding coolant should be done step by step, after all, I've been driving for many years. First, make sure the engine is completely cooled down, otherwise opening the cap on a hot engine can release steam that can cause burns—I've seen accidents happen, and it's quite scary. Then, locate the expansion tank in the engine bay, usually a white or translucent plastic container, unscrew the cap, and slowly pour in the dedicated coolant. Don't pour too quickly at once to prevent overflow. The fluid level should ideally stay between the MIN and MAX marks. After adding, tighten the cap, start the car, and let it run for a few minutes while observing the temperature gauge and checking the ground for any leaks. Also, it's important to note that the type of coolant matters—a 50/50 premixed antifreeze is best, and avoid mixing different colors or brands to prevent chemical reactions that could damage the system. Regularly replacing it every two years can prevent rust and extend the engine's lifespan.
