Where to Add Antifreeze in a Car?

[DiRobert]

Antifreeze is added to the coolant reservoir. Here are some precautions when adding antifreeze: 1. When adding antifreeze to your car, do not do it while the engine is hot. Since the vehicle is warm, opening the engine coolant reservoir abruptly may cause burns. If you are unable to add it yourself, it is recommended to seek a professional technician to avoid any complications during the process. 2. Pay attention when adding: antifreeze of different colors should not be mixed, as it can degrade the performance of the antifreeze. Generally, the freezing point of the antifreeze selected should be 10~15°C lower than the local minimum temperature to prevent the antifreeze from losing its anti-freezing function. Car owners should be careful when choosing to avoid selecting unsuitable antifreeze, which may affect the normal operation of the vehicle.

Last time I added coolant myself, I just looked for the transparent plastic tank in the engine bay, usually labeled COOLANT or with MAX MIN markings. It's typically located near the front of the engine or next to the radiator, so it's easy to find. Remember to always wait until the car has completely cooled down before opening the cap to add fluid, otherwise the high-temperature steam could burn you. Pour slowly and don't exceed the MAX line; if it's below MIN, top it up with the manufacturer-recommended coolant type, as mixing different brands can damage the radiator. I check the fluid level every month to prevent engine overheating and ensure effective antifreeze in winter. Developing this habit is super simple and can save you money on repairs.

Having driven for decades, my experience is that the coolant should be added to the expansion tank, which is clearly marked on the reservoir cap in the engine bay. The process is simple: park the car, turn off the engine, wait for the temperature to drop, unscrew the cap, and pour coolant up to the middle mark. Avoid overfilling as it can easily overflow. It's recommended to use dedicated coolant instead of water to prevent pipe corrosion over time. Check the fluid level every quarter; if it drops rapidly, there might be a leak, and immediate repair is necessary to prevent major issues.

I usually add coolant to the reservoir next to the engine, look for a small bottle marked with MAX and MIN. The location is easy to identify, and no tools are needed for the operation. Carefully open the cap when the engine is cold, wear gloves for protection, and slowly add the coolant to avoid spills. Maintain a moderate fluid level to ensure cooling efficiency; if it's too low, the dashboard warning light will come on. Consistently doing this small task keeps the car running smoother.
