3. Maxima 82964 Antifreezes & Coolants
The Maxima Coolanol green colored coolant is a ready to use 50/50 blend which consists of a blend of premium quality ethylene glycol based antifreeze mixed with deionized water which provides high quality corrosion and rust protection qualities for all aluminum and magnesium engines in motorcycles and ATV’s. This coolant also contains anti-foam components that reduces the water pump cavitation and increases the cooling capacity, whilst the blend also works to provide protection during freeze ups that occur in winter to as low as -34 degrees Fahrenheit. The coolant also initiates a maximum boiling system of up to 265 Degree Fahrenheit.
4. Mopar 10 Year/150,000 Mile Coolant
This OEM coolant is recommended for vehicles like FIAT, Alfa Romeo, Chrysler, Jeep, Dodge, Ram, SRT, and several others. The coolant comes in a 1-gallon can that is priced at only twenty bucks. It’s highly affordable and is perfect for the recommended vehicles. The coolant provides anti-boil and cold protection at -34°F (-37°C) and 265°F (129°C) degrees. The Mopar formula is made from monoethylene glycol using Organic Acid Technology (OAT). Therefore, this coolant is free of phosphates and silicates. OAT formula coolant is the newest type of antifreeze recommended for the latest vehicle models. The formula includes various corrosion inhibitors, which extends this coolant’s shelf life well beyond the average. This coolant comes premixed in a 50/50 ratio. There is no need to add water.
5. HAVOLINE High Performance Extended Life Antifreeze/Coolant
The compounds in Havoline High Performance Xtended Life contain no silicate, keeping your engine cool and running smoothly in the winter. Recommendations by Havoline states that you should change the coolant after driving more than 150,000 miles. It’s worth mentioning that this is an ethylene coolant, as with the most of the other coolants here and these should not be mixed with propylene coolant (Used in older cars.) Overall, this coolant is compatible with the most cars on the market with ethylene coolant. The coolant comes 50/50 pre-mixed with water. Which means that it’s ready to use in your vehicle and you do not have to mix it with water yourself and risking any damages to your vehicle, from the wrong mixed coolant.
6. Honda Type 2 Antifreeze Coolant
Honda is one of the few brands that went out and engineered their own coolant to best suit their engines, which lead to the creation of Honda Type 2. Some older Honda owners still use a different generic ethylene glycol coolant, but if your car has been running factory coolant all along, we wouldn’t recommend the switch over.
7. Preston Ready to Use Coolant
This is a safe product to use to top up your radiator whatever is already in your cooling system. This product is compatible with all other types of antifreeze and coolants and there is no need to match what is already used in the car’s cooling system. Most other products are not compatible and cannot be mixed.
8. Valvoline Maxlife Coolant
The patented Alugard Plus technology used in Valvoline MaxLife allows this antifreeze to provide optimum engine cooling even when mixed with antifreeze of other colors. Instead of flushing all of the engine coolant, a car owner can top off their antifreeze with this formula and be confident that it won’t cause excessive corrosion, which sometimes happens when mixing incompatible formulas. At a 50 percent dilution with water, Valvoline MaxLife has a boiling point of 265 degrees Fahrenheit and a freezing point of -34 degrees Fahrenheit. Valvoline uses yellow dye for this antifreeze, which they choose for color compatibility with other brands. Valvoline recommends this brand for use with both gasoline and diesel engines.
9. Royal Purple 01600 Coolant
This super coolant is one of the safest products since it does not contain any glycol. Car owners may use it with water only or antifreeze. Even though it does not provide freeze protection, it is compatible with cooling system additives that slow down or completely stop leaks. The good thing about this super coolant is that you can also use it in diesel engines. It helps improve heat transfer and reduces cavitation in this engine type. And since it is a high-performance radiator conditioner, it defends your engine from corrosion year-round.
10. KALIMEX LTD ST5501 Coolant Leak Repair

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.
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.
