Honda’s coolant contains ethylene glycol which protects all the aluminum parts inside your car’s radiator. Honda’s coolant is high quality but has quite a low life compared to other similar products.

This coolant comes Pre-mixed with 50/50 water and glycol, which is ready to use in your vehicle. But one thing about Honda’s coolant, like Audi’s coolant or any other branded coolant is that it doesn’t come cheap.

10. K-Seal Permanent Coolant Leak Repair

Best Engine Antifreeze & Coolant 2019 - Review & Buyer's GuideThis product is the last one on our list, and it’s not a coolant as the other ones in this list. Why we wanted to include this is to give you an alternative if you want to seal your coolant system from leaks. The K-Seal is made keeping old cars into consideration. It will cover the problems faced by old vehicles and their radiators. What makes this liquid different is that it will permanently fix the minor issues in the radiator such as minor leaks and the likes. That way, you don’t have to spend too much on the repairs on your old cars and easily get off with a cheaper alternative such as K-Seal’s permanent coolant.

It even goes as far as fixing the minor leaks and cracks in your car’s water body, heater, engine head so that really makes it up for lots of costly repairs. The liquid contains microfibers which start to clog and heal the cracks and leaks immediately as the liquid circulates throughout these and the whole system.
But let’s not forget its primary purpose.

Antifreeze & Coolant FAQ & Buyer’s Guide

As you maybe already know, the purpose of the coolant is not only to raise the freezing point. The purpose of the antifreeze is also to keep away rust from the inside of the engine and lubricate the moving parts in the coolant system like the water pump and thermostat. If you have tried to run your vehicle with only water, you did probably notice that the water gets brown really fast, and all that is rust from the inside of your engine. The engine antifreeze does also raise the boiling point, which makes your vehicle to not overheat as fast as with just water.

This becomes quite simply in places where it gets freezing. In such areas, water is no option. As the temperature drops, the water will freeze inside the radiator and the water body and ruin those components. Other than that, it will simply overheat your engine as there is no liquid to transfer the engine heat too.

Difference between Coolant or Antifreeze?

Audi Coolant AntifreezeCoolant? Antifreeze? Are these two things different? No longer. These two things are the same things and you can use both terms when you go in the market to get one for your car. In earlier times, these two were different. The antifreeze was made to be used with the coolant or water in the radiator. What that did was, had the antifreeze blend in with the cooling liquid in the radiator so that in the cold areas or under freezing temperatures, the antifreeze compound wouldn’t let the liquid in the radiator.

To make it simple, these two things came in separate bottles and would need to be mixed accordingly to keep the coolant from freezing in cold temperatures. But now, with the help of special compounds and blends, these two things come in a single bottle relieving you of the hassle of having to mix them yourself. So can you just directly pour in your radiator? It depends on the brand. Some companies sell ready products so all you have to do is simply pour it in. Some brands provide the liquid in concentrated form so you’ll have to take some time to properly dilute it with water.

How long before I need to change the antifreeze coolant?

A common rule is to change or replace your engine coolant is after driving your car for about 50 to 60K miles but that depends on a number of factors like your car’s make and model. Yes. Every engine is made differently in terms of performance and efficiency. An engine which is bigger and has more cylinders will heat up quicker than a car with a smaller engine. But that car will also have a bigger radiator and a powerful waterbody. So it depends on the vehicle type as well as the antifreeze coolant. As these liquids are made with special compounds, these lose their integrity after some time and that’s when it needs to be changed and replaced. The recommended time range is between 3-5 years between the coolant replacements, depending on the coolant. Check in your repair service manual to be 100% sure or check with the last coolant you added to your vehicle. If you are not sure which coolant you have in your car, the easiest way is actually to replace it with one that you know is good and fresh.

Coming to the coolants, there are different brands with the different techniques used in their coolants. Some brands claim that their coolants can work 100% for 50,000 miles, while some claim for as high as 150,000 miles. One thing to consider besides that is that coolants now provide more benefits other than just keeping the engine cool. These features are lubricating the seals and rubber parts in the radiator and waterbody of an engine, keeping these parts from rusting and corroding and as such. So that factor also counts in the life of a coolant. A coolant may lose its integrity quickly in an older model car with an already rusted radiator whereas, in a new car, the coolant may last for as long as it’s manufacturers claim.

Also, if you happen to use your car for great distances, it is advised that you change the coolant as per the advice of the coolant manufacturers and your car’s owner manual.

After the coolant replacement, you have to bleed your car carefully. This process can be pretty tough to do yourself if you do not have the skills for it. If you want to learn a bit more about this, check out overheating coolant article here: Overheating Coolant system.

Which antifreeze should I buy for my car?

The best bet is to refer to your car’s owner manual before you go out to get the coolant for your car. The manufacturers of your car will best know that which type of coolant your car needs and benefit the most from. You can also call your authorized dealer to get your question answered fast. Remember to not mix propylene and ethylene coolant. If you choose the first prestone coolant in this article, you can mix it with all different coolants.

Antifreeze for different types of engines?

As the gasoline engine runs differently than diesel engines, the parts and oil also differ. Petrol engines tend to get a bit hotter than diesel engines and because of that, vehicles with a diesel motor are susceptible to rust and corrosion happening on the internal engine parts. For that purpose, antifreeze liquids for diesel engines and made differently to comply with the requirements of diesel working and similar, antifreeze for gasoline. Mix your coolant for higher boiling point if you have a petrol engine.

Should I use Ethylene glycol for my car?

It is extremely important to know if your radiator can handle a particular antifreeze coolant you are getting or not as it can cause problems. Some car manufacturers make their cars equipped with radiators which can handle ethylene glycol. Some are sensitive to it due to the materials in making the radiator. So it is highly advised to check your car’s owner manual on which coolant your car initially came and which coolant types are friendly with your car and can be used in your radiator without actually damaging it further.

Some vehicles use aluminium blocks, and in this case, it’s also very important to use an ethylene glycol. Don’t take any risks, check your car repair manual before purchase.

How much water should I mix my coolant with?

If the coolant comes pre-mixed, use it as it is and don’t mix it with more water. This point is important as it determines if the coolant you have bought for your car is good enough for your car and the temperature in the area or state you live in. Your car’s temperature will work as per your radiator’s efficiency and the efficiency of the antifreeze coolant itself that you prefer to use. That is to say, choose the coolant wisely as some coolants feature a low-temperature. For instance, the temperature where you live drops constantly below the freezing point, the coolant needs to be able to retain enough heat so that it doesn’t freeze. If you live in warmer countries, you may not have to mix the coolant with a high freezing point as one in a cold country, but it’s always worth doing it in my opinion.

What happens if you use only water in your car?

As we discussed, water can work in places where the temperature doesn’t get that cold or drop below the freezing point better. But do note that while water may get you going fine for a few months, in the long run, your car may suffer permanent damage. Water will cause corrosion and rust inside the radiator and waterbody. Running on water may also cause your vehicle to overheat faster if you have problems with it from the beginning.

 

Tips before using antifreeze in your car

Now that you have gone through our list, you know that many brands offer their coolants pre-diluted without needing you to mix it yourself with water. Some manufacturers, like Audi and Honda, don’t sell their coolants pre-mixed, rather they are concentrated so that if your car’s owner manual has explicit instructions regarding the use of coolant, an owner can accordingly mix water with the coolant. Also, these instructions are usually present in the coolant bottle. If not, a small instruction manual is given with the bottle which states the mixing proportions so you don’t have to worry about mixing it wrong.

 

Conclusion

It is highly recommended to always try to buy high-quality antifreeze. That is why you need to use the excellent antifreeze you may purchase on your vehicles cooling device. There are in order that many benefits to doing that. Antifreeze isn’t always an expensive product in the market and it isn’t always worth it to try to save some money and which can have you to replace or restore an engine that has badly overheated or seized up; the cost alone for this restore would be exceeding the value of the car in some cases.

Your best bet is to find that antifreeze or the brand that features all those things which your car’s owner manual requires or the similar. That way, you’ll simply be on the safe side such that your product is compliant with your particular car. Use the purchase guide we offer for you in the antifreeze opinions as a reference when shopping for antifreeze as with this knowledge, you won’t be making the mistake of getting the wrong fluid for your car.

Without antifreeze, no engine will run for long under very hot or extremely cold situations. Oils would lose their viscosity and become so thin they could no longer do their process and once metal begins hitting different unlubricated steel inside the combustion chamber, engine failure will be imminent and you will have no choice but to have the engine rebuilt.
