The Best Motorcycle Coolant

It doesn’t matter if you ride a Harley or a Honda; having motorcycle coolant is essential. This important liquid helps your bike remain cool by transporting heat from the engine block to the radiator, where it is dispersed.

Over time and due to use, your motorcycle’s coolant can deteriorate, causing many mechanical problems. This is why you need to select a high-quality motorcycle coolant that has been designed to last.

Trying to figure out the best motorcycle coolant can be confusing; fortunately, ToolsPicks is here to assist you. This article will highlight the best motorcycle coolant products available, enabling you to make an informed choice.

There will also be a buying guide that provides you with essential factors you need to consider when purchasing coolant for your motorcycle. Before highlighting the best motorcycle coolants, it is important to first highlight essential factors to consider.

Buying Guide for the Best Motorcycle Coolant

The coolants highlighted in this article are the best out there, and there is no doubt one on the list that best suits your preferences. To help make your decision easier, we at Toolspicks have taken the time to compile this guide.

Ready Mixed

While it isn’t as important to buy a coolant that is ready mixed, it can help make things easier. Moreover, if you purchase a water-based engine coolant, a ready mixed option is best as it will most likely be made using deionized water.

Compared to tap water, deionized water is free from any minerals that might cause limescale or corrosion in your cooling system.

Long Service Life

The aim of taking care of your motorcycle is to have it working for a long time. A great way to do this is to choose a coolant created to last. When you choose a high-quality motorcycle coolant, you not only improve your fuel efficiency but also help prevent a host of mechanical problems and save money.

High Boiling Point

The best motorcycle coolant is one that comes with a high boiling point. Such coolant is capable of transferring the heat away from your engine. This is why it is imperative to find a coolant with a high boiling point – of at least 250 F.

Antifreeze Protection

Coolants made today have been designed to provide year-round protection to your engine. This is achieved by including antifreeze in the mix, so you should be looking for coolants that can protect your engine at colder temperatures.

Corrosion Resistance

The best motorcycle coolant comes with anti-corrosion additives that help prevent deterioration in your cooling system. Furthermore, the coolant you select for your motorcycle should be free from carboxylates, borates, phosphates, nitrates, and silicates.

Type of Coolant

Reading the list of the best motorcycle coolant below, you will discover that they come in two major types: water-free and water-based.

Water Free

Waterless coolants don’t contain water meaning their composition helps to eliminate the probability of corrosion in your motorcycle’s cooking system. This, however, does make them expensive to purchase. Fortunately, the chemicals utilized to make the coolants come with a higher boiling point and heat capacity than water-based coolants.

This design allows heat to be transferred away from the engine more efficiently. This increases efficiency and makes waterless coolants perfect for high-performance conditions. They also tend to last a lot longer than water-based motorcycle coolants.


As the name suggests, water-based coolants contain water, with around 50% of the entire volume made up of water. Depending on the brand, you can purchase a water-based coolant ready mixed or one that requires you to add water.

This coolant is the most commonly used type as it is much more cost-effective compared to waterless coolants. Nevertheless, you should note that water-based coolants have a lower boiling point making them unsuitable for certain applications such as racing. Moreover, water can be quite corrosive to your cooling system if it contains certain minerals.
