Can I Add Water If the Coolant Is Insufficient?

[CarolineRose]

You can add water if the car's coolant is insufficient, but it is best to add coolant. Here are the specific details: 1. The benefits of coolant include antifreeze, cleaning, rust prevention, effective cooling, and a high boiling point. Water cannot meet these standards, and adding ordinary water can easily cause rust and clog the radiator. 2. In an emergency, you can add water, preferably distilled water, but this is only to prevent overheating due to insufficient coolant. 3. After adding water, the freezing point decreases. At this time, you should promptly check the coolant's freezing point based on the surrounding temperature. 4. If used for emergency purposes, you can add water, but after the emergency, you must drain the water and replace it with coolant.
