Can car coolant be replaced by water? What should I do if the car water tank is broken and cannot be opened?

We all know that windshield washer fluid can be replaced with water and detergent, but can coolant be replaced? We must first understand the role of coolant: coolant is also called antifreeze coolant. As the name suggests, it cools the engine temperature, keeps the engine at a certain temperature, and runs smoothly. Let's see if it can be replaced!

Can water be used instead of car coolant?

No, the functions of coolant include anti-corrosion, anti-rust, anti-scaling, anti-boiling and anti-freezing.

1. Most of the parts in the car are made of metal, such as copper, iron, aluminum and steel. These metals will corrode and rust over time when in contact with water at high temperatures. This is when the role of antifreeze comes into play. It not only does not corrode the cooling system of the engine, but also has anti-corrosion and anti-rust functions.

2. I believe that many friends will have a layer of something on the wall of the water cup when they drink water, that is scale. Using water instead of coolant will cause a lot of scale in the water tank and water circulation system, causing the car to run at high temperatures, and it is also very difficult to clean. High-quality antifreeze usually uses distilled water and is added with anti-scaling additives, so it not only does not rust, but also has the function of descaling.

What to do if the car radiator is broken and can't be opened

Water cannot replace coolant, but what if the water tank breaks on the road and the engine is overheated and cannot be driven? At this time, you can add water to the water tank for short-term driving and emergency use, but not for long-term use. You should drive to a repair shop as soon as possible to repair and replace the coolant.

The coolant has the properties of a high boiling point (105°C) and a low freezing point (-68°C). It has low foaming and anti-corrosion additives, is anti-corrosive and anti-scaling, has a higher boiling point than water, and can prevent boiling. In addition, in cold weather, because it has a lower freezing point than water, it can effectively prevent freezing, bursting pipes and water tanks, and will not produce scale like water, clogging pipes.

The role of automobile coolant

The coolant has a high boiling point. We all know that the boiling point of water is 100°C, and the boiling point of high-quality antifreeze is usually above 110°C. So when we use it in the summer, it will prevent the water from boiling and causing damage to the vehicle.

The full name of coolant is antifreeze coolant. Its main function is to prevent freezing when parking in the cold winter. The coolant can prevent ice from forming, which can cause the radiator to burst and the engine cover or body to freeze. Finally, I would like to remind you that antifreeze is not only used in winter, but should be used all year round.

We all know that the working of the piston and cylinder of a car engine requires cooling. This cooling task must be completed by antifreeze, water pump, electronic fan and other parts. The engine cylinder is composed of many parts. If tap water is used, it will cause rust and corrosion inside the engine, which can easily cause high temperature. High water temperature will cause great damage to the engine.
