Where to Add Antifreeze in a Car?
2 Answers
Antifreeze is added to the car's coolant reservoir, also known as the radiator, which is a key component of the car's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car's engine. When adding antifreeze, avoid doing so when the engine is hot, as opening the radiator cap on a hot engine may cause burns. If you are unsure about the process, it is recommended to seek assistance from a professional technician to avoid complications. Additionally, note that antifreeze of different colors should not be mixed, as this can degrade its performance.
I've been driving cars for almost 30 years. The antifreeze is added to that white or transparent plastic container in the engine compartment, commonly called the coolant reservoir or expansion tank. It's usually located near the radiator at the front of the engine, with clear markings on the cap like a water drop or thermometer icon, labeled "coolant" or antifreeze. When adding it, always wait until the engine is completely cool, then simply open the cap and pour it in - keeping the fluid level between the MIN and MAX marks is safest. Early on, I once tried adding it to a hot engine and got sprayed with boiling liquid that burned my hand - a painful lesson learned. Now I check it regularly every month, using a flashlight for better visibility. Antifreeze mainly prevents freezing in winter and overheating in summer, with the ideal mix being 50% antifreeze and 50% distilled water - supermarkets sell pre-mixed versions for convenience. If you don't add it correctly, the engine can overheat and break down, leading to expensive repairs.
