Best Antifreeze and Coolants for Cars, Trucks & SUVs

Vehicle coolants and antifreeze is often overlooked by owners, but it is one of the key products to ensure that your engine is in pristine condition. The cooling system of the engine works to prevent your engine from overheating and of course some coolants are better at this than others.

Coolant is usually mixed with water and then poured into the reservoir and radiator of the vehicle which then needs refilling at regular intervals. Some coolants have ingredients which break down over time, which make you need to flush out the entire system every so often. The best antifreeze and coolants don’t cause this.

To put it simply, antifreeze and coolants increase the freezing and boiling points of your vehicles fluid so it reaches these maximum limits later than it ordinarily would. This increases your vehicles threshold for overheating and freezing, by acting as a lubricant for the moving parts within the engine and any parts that the fluid comes into contact with. This generates a smooth and easy operation.

Coolants may seem like a simple product and it doesn’t matter which one you choose, however there are many different types of coolants that serve different purposes. As a result, it can be difficult to know what the best antifreeze coolant product is, but we’ve created this extensive guide to may it easy to choose.

Buying Guide

Types Antifreeze/Coolant

You may be wondering why there are so many antifreeze variations, but it’s because there needs to be different formulations for different countries. Traditionally, European countries have harder water and because antifreeze is 50% water the water quality affects the overall antifreeze mix.

Because of this, European manufacturers reduced the amount of phosphates in their antifreeze whereas Japanese manufacturers were reducing their use of silicates which tend to destroy the seals of water pumps.

In recent years, formulations have become increasingly advanced which can last as long as 10 years which translates to around 130,000 miles.

Inorganic Acid Technology

This is often abbreviated to IAT, and is the chemical form for the traditional green colored antifreeze which allows it to be easily identified. It is usually fortified with silicate or phosphate additives to make it compatible with metal cooling system components. It is extremely popular for US manufactured vehicles and has been for decades.

Its recommended that this antifreeze be flushed out of your engine system every 30,000 miles or two years.

Organic Acid Technology

Is commonly referred to as OAT and is a long life coolant which is widely used in Europe but is growing in popularity within the US. Compared to inorganic acid technology, OAT coolants contain no silicates or phosphates, so they are considerably more long lasting than IOT coolants.

Manufacturers have also added in additional ingredients that protect your engine from rust and corrosion. It usually lasts for a duration of 150,000 miles or five years and usually comes in an orange color.

Hybrid Organic Acid Technology

This type of coolant are available in a number of different colors and combines IAT and OAT coolants with nitrates, whilst it also contains silicates that work to reduce the level of corrosion and rust. Similar, to OAT, this type of coolant needs to be flushed every at regular intervals, either every 5 years or 150,000 miles.


The brand you decide to purchase will be linked to the overall quality of the product and how well it will function. The better brands that are more reputable will deliver a longer lasting consistent performance, whereas the less well known brands may be just as good quality but you will be taking a leap of faith hoping that it will perform.

Higher quality brands will also be compatible with a larger range of vehicles and engine types which means that you can spend less time worrying about whether it will work in your engine and more time focusing on things that matter.

A high quality brand will give you the peace of mind that it will not damage the inside of your engine, and throughout this guide we will highlight the top brands and their associated products.

It is generally long lasting so you won’t need to keep replacing your bottle.

Level of dilution

Its important to take not of the water dilution level that’s needed for your chosen coolant. Some are supposed to be used directly out of the bottle, whereas others are supposed to diluted with water. Poor engine cooling is often caused by using a coolant mixture that’s either too strong or weak, which is a bad outcome.

Vehicle Type

Its hugely important that you ensure that you use the correct antifreeze that’s compatible with your vehicle. This will vary depending on the manufacturer and model of your vehicle and most will have a particular coolant that’s best suited.

The best way to identify which coolant is best for your vehicle is to refer to your vehicles manual and if this is unavailable you can search through their website where it will be listed. If both these suggestions fail, then you can ask your local mechanic or auto shop for advice.

Safety Precautions

Although this won’t directly affect your final buying decision, however coolants can be highly hazardous if ingested or comes into contact with your skin for long periods of time. Antifreeze poisoning is fatal to humans and can also lead to serious health issues and complications and shouldn’t be taken lightly and always must be handled with care can kept away the reach of pets and children.

Antifreeze should either be stored at a height or ideally locked away in a cupboard or cabinet so you don’t accidently spill it. If it does get ingested, then you will need to visit the nearest hospital or emergency health provider immediately.
