What Is Coolant Exactly
Coolant is commonly also called antifreeze. It is comprised of a 50/50 mix of ethylene or propylene glycol and water. Coolant/antifreeze is added to a vehicles cooling system, which circulates the fluid throughout the engine and radiator to prevent overheating. If your vehicles cooling system is functioning properly, it will effectively reduce the heat produced by the engine and keep everything running smoothly. Without regular coolant service, the cooling system may not function as it should, causing the engine to become too hot and cause damage such as warped heads, blown head gaskets, or even engine failure.Coolant is also called antifreeze because, as the name suggests, it will not freeze even in extremely cold temperatures. As coolant keeps the engine from overheating it also keeps it from freezing up when left to sit in the cold. Frozen fluid may prevent your car from starting on cold winter mornings.
It is important to make sure that you have enough coolant in your vehicle at all times to stave off premature coolant system corrosion, as well. The best way to stay on top of potential problems with your coolant system is with regular coolant service as a trusted auto repair shop.

What Is The Anti
As we already clarified, the anti-freezes a part of the coolant that prevents water from freezing quickly. In other words, anti-freeze helps water drop its freezing point below the specific numbers, so coolant helps serve your vehicle in very cold environments.
Thus, when coolant consists of a mixture of water antifreeze, it achieves new characteristics. These characteristics include operating up to 200 degrees without issues with evaporating and operating at minimum temperatures up to 30 degrees below zero without any issues with coolant freezing.
Anti-freeze consists of many interacting chemicals. The most important one is ethylene glycol, which is responsible for reducing the freezing point for water when the temperature gets extremely low. Furthermore, it helps lubricate the internal engine components to keep them working properly.
Anti-freeze comes in two common colors, orange, and green. While people think that these colors don’t mean anything, the orange color indicates that this entire freeze lasts much longer than the green one. It also has certain additives to help prevent corrosion.
With that, if you’re still wondering and looking for antifreeze vs. coolant, you should immediately know that anti-freeze is not coolant and cool. Instead, it needs both a mixture of water and antifreeze and extra additives to help add certain characteristics to the coolant. These characteristics help prevent freezing and enhance the vehicle’s engine’s performance.

When Should I Change The Coolant/antifreeze
Youll need to have the coolant/antifreeze in your cars engine cooling system flushed and replaced from time to time. And because of its importance, its vital you keep a regular check on the condition of the fluid.
So, pop the bonnet, locate your coolant bottle and remove the lid. Take a sniff and if the fluid smells hot and burnt then its time to have it flushed and filled with new coolant/antifreeze. More than that, youll need to check and find out what caused your system to overheat in the first place, so take your car in to your mechanic.
Similarly, if you look at the fluid and it looks a little milky then its possible that oil has got into the system via a leaking head gasket or transmission cooler or the intake manifold. And this can kill your cars engine. Get the car to a mechanic ASAP.
Ideally, the coolant/antifreeze should look a vivid green and it should feel slippery, like oil. If it feels gritty to the touch, then you should get the cooling system flushed and replace the fluid mix. You dont want to risk scale or rust being washed around your cooling system which could cause the water pump to seize and the engine to overheat.

What Is Coolant Made Of It’s Just Water Right
Coolant is normally a concentrate fluid, usually made of Ethylene Glycol together with some protective additives that is mixed with demineralised water to produce coolant. Propylene Glycol, which is non-toxic, is sometimes used in the mixture, as well as, or even instead of, the more toxic Ethylene Glycol.
Glycol does not absorb heat as effectively as water, but when added to water it has the ability to lower the fluids freezing point as well as raise its boiling point. A common Glycol to water ratio used is 50:50. This will lower the freezing point of the fluid to minus 39°C and raise the boiling point to 108°C. Manufacturers can recommend other specific mixture ratios, but below 33.5% Glycol the coolant will give inadequate freeze protection, and above 65% Glycol the mixture has inadequate heat absorption.

When Coolant Should Be Flushed
After learning what coolant does my car need and the proper coolant mixture, lets see when should the coolant should be flushed.
As you know, coolant is not something that will last forever. The engine coolant has to be flushed at precise intervals. Or refreshed before the winter so the vehicle does not freeze at below-freezing temperatures.
So, when should the coolant be flushed for optimum performance of the cooling system? Lets elaborate.
Lets say you are having an older car and you use the IAT also known as green coolant. In this case, you will have to flush the coolant every 3 to 4 years or at about 30,000 miles.
If you run a more modern solution like the OAT and HOAT types of coolants you will have to replace the coolant every 5 years or after 50,000 miles. Meaning that these coolants have a quite longer lifespan.
Also, whenever the coolant is 3+ years old it is often advised to refresh it a little bit. Release some coolant from the expansion tank and pour some concentrate to make the coolant stronger. Overall, thats it when it comes to what coolant does my car need and also the change interval of coolant. Now lets see how you can flush the coolant at home using common tools.
After How Long Should I Change My Coolant
Coolant deteriorates with time. Therefore, it is recommendable to check your engine coolant at least twice a year.
Alternatively, you can schedule your checks after every 30,000 or 50,000 miles. If the coolant level has gone down, you should top it up.
Also, a regular antifreeze flush and coolant drain are necessary

Aside from those general guidelines, you may have an issue with your antifreeze or the cooling system if you notice:
- An oily or sludgy layer on top of the antifreeze.
- An extremely low level of coolant.
- Cracked radiator hoses.
- Colorless or rust-hued antifreeze.
- Particles floating in the antifreeze.
These are all indicators that you should take your vehicle to a professional for an inspection. A reliable mechanic can let you know what’s going on and recommend the right repair for your cooling system. Don’t ignore these issues, as they could cause irreparable damage to your engine.
What Is Engine Coolant
Engine coolant keeps your engine from overheating and helps you avoid a costly repair bill. Coolant helps protect your engine from extreme temperatures, both hot and cold. Your cars engine runs hot while in use, hot enough to damage essential parts. The coolant absorbs the heat from the cars engine and circulates back to the radiator. During the winter, extreme cold can cause your engine block to freeze and even crack. Coolant prevents both overheating and freezing. True to its name, engine coolant, aka antifreeze, does not freeze in sub-zero temperatures. Commonly referred to as antifreeze, engine coolant contains ingredients that help prevent corrosion of your cars engine parts. Engine coolant comes in several different varieties, but its basic ingredients include ethylene or propylene glycol and water.
Your cars radiator has a reservoir that stores engine coolant. From that reservoir, coolant flows into and circulates through the engine block, protecting your vehicle from extreme heat or cold. The coolant system works as a simple loop. A pump will send engine coolant to your engine block when the car is running. From there, the coolant will run to the cars radiator, also called the heat exchanger, and then back to the pump. When you first start your car, allowing the engine to warm up, the coolant will bypass the radiator. As the car heats up, the coolant system valve will allow the coolant to flow through the radiator.

Can I Put Any Type Of Coolant In My Car
Years ago, when full service gas stations were common place, the attendant had only one option for topping up coolant in your car, it was green. Today we have multiple choices of coolant, each which their own specific concoction to improve the cooling system of your car.In order to answer the question, lets discus coolant and how it works. Coolant in its base form is Ethylene Glycol. Now most people will be surprised to hear that coolant plays almost no role in the actual cooling of your engine. Engine cooling is done by the 50/50 mixture of distilled water in the radiator. The Job of the coolant is simply to inhibit rust and lower the freezing temperature of the water.
The need for different types of coolant came about when manufacturers started using more exotic metals for their engine blocks, heads and gaskets. Some metals require more rust inhibitors than others, while some require the ability to dissipitate heat faster than others. The type of coolant your car requires is simply based on the types of metals in your engine.
