Which port is used to add car antifreeze?
2 Answers
Car antifreeze is added through the auxiliary tank port, and the method of adding it is as follows: 1. Open the engine hood; 2. Unscrew the cap of the auxiliary tank and rotate the cylinder block and radiator drain switch; 3. Add the car antifreeze. Precautions for adding car antifreeze: 1. Avoid mixing different types of car antifreeze; 2. Clean the cooling system before replacing the car antifreeze; 3. Check the liquid level of the car antifreeze. The functions of car antifreeze are: 1. Preventing corrosion and rust in the engine; 2. Removing scale from the engine radiator; 3. Preventing the engine cylinder block from cracking; 4. Extending the service life of the engine.
I've been driving for over ten years and often maintain my vehicle myself. Adding antifreeze requires choosing the right spot, or it can easily cause problems. After the engine cools down, open the hood and look for the plastic reservoir—it’s usually marked with a small label saying 'Coolant' or 'Antifreeze,' often placed prominently on one side. I just unscrew the cap and pour it in, but before adding, I check the fluid level markers—it shouldn’t exceed the MAX line or go below the MIN line, or it’ll affect cooling efficiency. The type of antifreeze matters a lot; I always follow the manual and use a pre-mixed brand, never pure, to avoid cracking components. I learned the hard way—once I opened the cap when the engine was hot, and scalding fluid sprayed out, burning my hand. It was pretty dangerous, so now I always wait a few hours before handling it. I check the level before winter and top it up if needed—it protects the engine from freezing and overheating, preventing breakdowns. If the level drops too fast, there might be a leak, so I take it to the shop to check the hoses. This simple routine has saved me a lot on repairs and extended my car’s life. In short, a quick top-up gives me peace of mind.
