How to choose engine coolants

Breaking down what engine coolant actually is and how it works is crucial when searching for the ideal product to keep your engine purring proficiently. In this simple buying guide, we’ll discuss the different types of coolant, their properties, and the subsequent effects they’ll have on your vehicle.

Ensure That the Coolant Is Compatible With the Make or Model of Your Car
The first thing to consider when shopping for an engine coolant is that it’ll be compatible with your car. Many coolants are suitable for use with all makes and models of vehicle – these are ideal for ordinary cars that don’t require a specialist product. On the other hand, premium coolants are designed with higher-end car manufacturers in mind. They use top-quality ingredients that are officially approved for use on vehicles by companies such as Audi, Bentley, Mercedes Benz, and Volkswagen. If your car is your pride and joy, you should definitely make sure you pick this kind of coolant as it’ll deliver the best results! You can also find coolants that cater specifically to one type of engine, such as those in cars made by Ford. These are designed and manufactured by a certain company only for their cars. They’re typically more expensive than all-purpose coolants though, as you’d probably expect!

Concentrate or Ready-Mixed? Making Sure You Pick a Suitable Formula
Knowing the difference between concentrate and a ready-mixed coolant will ensure that you don’t have any nasty surprises with your engine, but each type has pros and cons.

Determine the Temperature Range Before You Buy
ach coolant product will have a specific temperature that it’ll freeze or overheat at. This temperature protection scale is incredibly important to consider – as we’re sure you know, the weather is rarely predictable here in the UK! Whether preparing for the “Beast from the East” or a scorching summer heatwave, buying a coolant that can combat any type of weather is paramount in keeping you rolling all year round. To help you out, we’ll share both the freezing and overheating temperatures of each product in the specification table below the review.

The Anti-Corrosive Technology That the Coolant Uses Will Affect Its Longevity
Coolants generally have anti-corrosion properties which prevent the metal inside your vehicle from deteriorating, but these only last for a certain amount of time before the coolant needs to be flushed out and replaced. These days, most coolants come with organic acid technology (OAT). These organic acids are better for the environment and give the product long-lasting corrosion protection of up to 10 years! However, if your car was made before the year 2000, it’ll probably need a coolant with inorganic acid technology (IAT) or hybrid organic acid technology (HOAT) instead. These use silicone to combat corrosion, but they aren’t as long-lasting as OAT. IAT coolants will only give your engine 2-3 years of protection, while HOAT products will protect your engine for up to 5 years.

Check the Size to Make Sure You’re Getting a Good Deal
Buying online can sometimes entail receiving a product, opening it up, and realising it’s half the size of what you imagined. This is why it pays to check the volume in litres before hitting the “buy now” button, so you know that you’re definitely getting a decent deal – not one that’s too good to be true! If, as we mentioned earlier, the type of coolant will need changing every 2 or 3 years then you should probably go for a bigger bottle that’ll provide several refills. Those who only need to change their coolant every 10 years, on the other hand, won’t require as much. Checking the volume against whether a coolant is concentrate or ready-mixed is also important, as concentrates can double in size once you’ve added water.

Conclusion

We’d suggest your first step should be to decide what type of engine coolant that you like the best. Once you’ve made that decision, try and set yourself a bit of a budget, so you can filter out the gloves that don’t fit in your price range and find out the best engine coolants for yourself. And finally use our recommend to help you narrow down your search.
