Coolant, or antifreeze, is generally a half-and-half mixture of a form of glycol and water. The glycol represents the antifreeze element of the mix, guaranteeing that the fluid doesn’t turn into ice under harsh winter conditions. Glycol also prevents the coolant from reaching the boiling point in extreme heat.

What is the main ingredient of engine coolant?
All automotive coolants are glycol-based. Common coolants consist of a mixture of ethylene glycol with additive packages and some water. Another glycol-based coolant consists of propylene glycol and water. The major difference between the two types is that propylene glycol is less toxic.
Can you use water as engine coolant?
Water by itself can’t do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle’s engine. Plus, it doesn’t absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
Is engine coolant and antifreeze the same thing?
Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
Is coolant made of oil?
We all know we need to put oil in our engines to keep it lubricated, but did you know that your antifreeze is derived from oil as well? Yet another feat of petrochemical engineering, antifreeze is used to both as the name suggests—to keep the coolant system from freezing—and inversely, to keep it from overheating.
How can I make my own car coolant?
How to Make Radiator Coolant
- Pour one gallon of the antifreeze of your choice into a large bucket or large mixing jug.
- Pour one gallon of distilled water into the bucket or mixing jug.
- Mix them together thoroughly and use the coolant blend in the car’s radiator. Store the coolant blend in a large, tightly sealed jug.
Is coolant better than water?
While water does help to keep your engine cool, it does not work nearly as well as coolant does. First of all, water boils faster and at a lower temperature than coolant. If it is winter, then you risk having your engine block crack if you run your engine with only plain water.
Can I top up coolant with tap water?
No, you should use distilled water or better yet, de-ionized water. The reason for this is that tap water has minerals that can deform deposits inside the radiator and the cooling system passages of your engine.
Is it OK to drive with low coolant?
No, it is not safe to drive with a low engine coolant level. Low engine coolant can cause airlocks in the coolant system and an overheating engine can destroy expensive parts like the engine block or seize it completely.
Can I drive a car without coolant?
So, in summation, it is best not to drive your car without coolant. If you discover that you are running low and there is no gas station nearby, then it is recommended that you should call for assistance. Do not continue to drive as you may end up permanently damaging your engine.
Does coolant affect AC?
Yes, coolant can affect a car’s air conditioning by impacting the car’s temperature, humidity, and airflow.
What happens if you put coolant in the radiator?
If you add coolant when the engine is hot, you run the risk of causing serious injury. The radiator is under a lot of pressure when the engine is running and hot, and if you were to open it while this was happening, boiling coolant could come rushing out and cause severe burns.
How long does coolant last for?
HOW OFTEN SHOULD YOU FLUSH THE COOLANT? Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.
What happens if you mix water and coolant?
When water is mixed with antifreeze (which is made of a chemical called ethylene glycol), the freezing point is bumped down to -35 degrees, and the boiling point raised to 223 degrees Fahrenheit.
Why is coolant dirty?
Contaminated coolant: A bad head gasket or cracked cylinder head can allow oil and coolant to mix, resulting in sludge. In vehicles with automatic transmissions, the engine-cooling system also cools the transmission. A breach in the system can contaminate coolant with transmission fluid.
Can you mix engine oil and coolant?
Oil mixed with coolant will no longer be able to properly lubricate the internal components of an engine, while coolant mixed with oil will fail to keep the engine at a consistent temperature.
What happens if you don’t add water to coolant?
3 is that water must be mixed with the antifreeze-coolant in order to keep the performance additives (silicates, phosphates and nitrates) suspended. Without water, these important additives tend to settle. If they do that, you lose anti-corrosion and other additive protection.
Why is my coolant low but no leaks?
If you’ve ruled out an internal leak, that means your engine is burning the coolant somewhere else. The most common place is the radiator cap. Radiator caps hold the pressure inside the system, but if it’s not sealing properly, then some hyper pressurized coolant will escape in the form of steam.
How long after adding coolant can I drive?
How long do I run the engine after adding coolant? “Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.”
Why is my car going through coolant so fast?
Antifreeze leaks can be caused by a variety of things but the two most common factors are age and dirty coolant. Dirt or oil in your coolant can accelerate wear in your system, leading to leaks in your water pumps, at gaskets, or at o-rings. Flushing your cooling system is the best way to stop this type of leak.
How often should you need to top up coolant?
Antifreeze should be replaced every 3-5 years depending on how often and how far you drive your car, its age, and the temperature of where you usually drive. Extra care needs to be taken in the summer months, especially if it’s a hot day, so make sure you check your coolant levels before the start of the summer.
