Best ATV Coolant

Proper ATV maintenance is vital to keep it running at a high level. This includes using the best ATV coolant to help regulate engine temperatures.

The best ATV coolant includes the Engine Ice Hi-Performance, Maxima 82964 Coolanol Performance Coolant, Polaris 50/50 Premix Extended Life Coolant, and Can-Am Extended Life Pre-Mixed Coolant. You should use an ethylene glycol-based coolant mixed at 50/50 with water.

ATV coolant circulates through the engine and radiator to keep it from overheating. It also helps to keep the engine parts and other components from corroding by removing moisture and contaminants from the system. We review the best ones worth considering below.

‍4 Best ATV Coolant

Coolant is used to regulate the temperature of internal combustion engines, such as those found in ATVs. It transfers heat from the engine, regulates the temporary, and decreases the likelihood of overheating.

Overheating can occur when the engine works hard, such as when climbing steep hills or when the ATV is ridden in hot weather. If the engine gets too hot, it can seize up and become permanently damaged, which can be costly to repair.

It also helps to protect the engine from corrosion and wear. It is typically made from a mixture of water and an antifreeze agent, such as ethylene glycol, which helps lower the coolant's freezing point so that it can be used in cold weather as well.

With all of these factors in mind, it’s clear why coolant is so essential. We have listed the best options worth considering below.

1. Engine Ice Hi-Performance

We recommend Engine Ice Hi-Performance as the best overall ATV coolant. It uses a blend of water and propylene glycol, which has been proven to be the best for use with engines.

It also features a patented corrosion inhibitor that prevents rust from forming on metal surfaces and a patented biocide that helps prevent bacteria and algae from growing in the coolant.

This coolant is ideal for regulating the temperature in the engine, keeping boil-over temperatures to 256 degrees Fahrenheit or less. It also works in the cold, keeping freeze-up protection to -28 degrees Fahrenheit.

It’s incredibly durable and easy to use and has compatibility with nearly all ATVs, UTVs, and other high-performance off-road vehicles.

2. Maxima 82964 Coolanol Performance Coolant

The Maxima 82964 Coolanol Performance Coolant is a concentrated, long-life, non-toxic, and environmentally safe formula with excellent durability.

This means that it will last longer than other products on the market without needing any replacement or additive. It’s also made with a 50/50 blend which works flawlessly in aluminum engines found in motorcycles and ATVs.

This premium quality ethylene glycol-based coolant will provide excellent rust and corrosion resistance for the engine too. It also raises the boiling point in the engine to 265 degrees Fahrenheit.

This coolant is also a low-silicate fluid, which can benefit many power sports vehicles. It works best to protect the engine while increasing its cooling capacity.

3. Polaris 50/50 Premix Extended Life Coolant

The Polaris 50/50 Premix Extended Life Coolant is one of the best ATV coolants on the market. It is a high-performance, long-life coolant that has been developed to provide optimum protection for ATVs.

It has a high boiling point and low freezing point, which makes it suitable for extreme weather conditions. It also contains corrosion inhibitors to prevent corrosion in the ATV engine's cooling system and other parts.

The coolant also has antifreeze additives to ensure that it does not freeze at low temperatures. It can also be used in any type of weather, including when the temperature drops below freezing.

4. Can-Am Extended Life Pre-Mixed Coolant

The Can-Am Extended Life Pre-Mixed Coolant is a great product for all types of ATVs. It has a high concentration of corrosion inhibitors that will protect your engine from corrosion and rusting, which can lead to expensive repairs.

The coolant also has a high boiling point and an extended life span, which means that it will last much longer than other brands of pre-mixed coolants.

It’s highly rated with an estimated five-year lifespan. It also provides superior heat transfer, keeping the engine temperatures well-regulated for better safety.

What Type Of Coolant Works Best For ATVs?

The best coolant type to use for ATVs is a 50/50 ethylene glycol-based coolant with water. This works best with the style of engine most ATVs run.

However, the type of coolant that works best for ATVs will depend on the specific make and model of the ATV and the operating conditions in which it will be used. For example, many brands make unique compounds for their own vehicles.

This is true for brands like Polaris or Can-Am. But besides the coolant brand, we have other factors to consider to ensure it works well and provides the best compatibility with an ATV.

In general, coolant for ATVs should be a mixture of water and an antifreeze agent, such as ethylene glycol, to help lower the freezing point of the coolant.

This is important because ATVs are often used in various temperatures and weather conditions, and the coolant needs to function effectively in both cold and hot temperatures.

Using a high-quality coolant specifically designed for internal combustion engines is also important. This will help ensure that the coolant can transfer heat away from the engine and prevent overheating.

How Much Coolant Does An ATV Need?

In addition to using the correct type of coolant, it is also important to maintain the proper level of coolant in the engine. Failing to do so can result in engine damage and costly repairs.

This can typically be checked by using a dipstick or by checking the level of the coolant reservoir. The average ATV needs roughly 2.5-3 quarts of coolant when refilling the tank, and this level should be monitored regularly.

It’s a good idea to check the coolant levels every 2-4 weeks, especially in extreme temperatures. This is when coolant is most important.

What Happens When You Don’t Use ATV Coolant?

Coolant is essential and needed to drive an ATV safely. Without it, the engine is put in a difficult situation with risks like poor lubrication or lack of temperature control.

Not Enough Engine Lubrication

Coolant also helps to protect the engine from corrosion and wear by providing lubrication for the moving parts. Without it, these parts could become damaged and wear out more quickly, resulting in costly repairs.

Inability To Regulate Engine Temperature

If you don't use coolant in an ATV, the engine could overheat and become seriously damaged. Coolant helps regulate the engine's temperature by transferring heat away from the engine and into the surrounding air or water.

Without coolant, the engine could get too hot and potentially seize up, which can cause serious damage and be costly to repair.

Key Takeaways

• The best ATV coolants include the Engine Ice Hi-Performance, Maxima 82964 Coolanol Performance Coolant, Polaris 50/50 Premix Extended Life Coolant, and Can-Am Extended Life Pre-Mixed Coolant.
• The average ATV needs about 2.5-3 quarts, which should be flushed and changed every 3-5 years.
• Without coolant, the ATV engine doesn’t have enough lubrication to avoid rust or corrosion and cannot regulate temperatures.
