10 Best Motorcycle Coolant – Reviews and Guideline 2020

Best Motorcycle Coolant

When replacing your motorcycle engine coolant, you can easily get confused about the best motorcycle coolant to buy to keep your engine running at safe temperatures.

You’d also want to carefully tread the coolants world to avoid getting lured by poorly made coolants that contain chemicals that do more harm than good to your bike engine.

This is where we come in…we went searching for the best quality motorcycle coolants which contain safe additives for your engine. We found the10 top-rated motorcycle coolants which we’ll share with you below.

Is Car Coolant Okay For Motorcycles?

BEFORE we outline our top products, let’s address one of the most discussed questions on various motorcycles forums…

Can you use a car coolant for your motorcycle?

The short answer is yes and no.

Confusing, right?

Let’s make it easier to understand…

Depending on the type of car coolant you have at hand, you might be able to safely use it on your motorcycle.

BUT…before you do that, you need to check a few things to ensure it’s 100% safe for your motorcycle engine and transmission.

Firstly, the car coolant MUST contain ethylene glycol. For starters, this is an antifreeze substance with an incredibly low freezing point.

Secondly, the coolant MUST NOT contain any silicate. Silicates are anti-corrosive chemicals that are quite helpful in cars as they help inhibit aluminum corrosion. For motorcycles, however, they can attack your water pump or seals. This explains why all motorcycles coolants are silica-free.

As you can see, car coolants might not be safe for motorbikes.

Instead of going through all the hassle of trying to establish whether the car coolant you have contains the chemicals mentioned above, we suggest that you go for motorcycle-specific coolant.

See, the motorcycle coolant is specially formulated for your bike, so you’re 100% sure it contains just the right composition of chemicals and additives for your bike’s engine.

Since you’ll be replacing your coolant only once every 2 years, there’s no point in endangering the life of your motorcycle engine just to save a few bucks.

Let’s look at some of the best coolants you can get for your motorcycle today…

What To Look For Before Buying?

When shopping for the perfect coolant for your motorcycle, the following factors must come into play:

Boiling & freezing points

The ideal coolant for your motorcycle should have high boiling and freezing points.

A coolant that comes with a high boiling point will do a better job at channeling away heat from your motorcycle engine. Look for coolants with a boiling point of over 200 degrees Fahrenheit.

The coolant should also have the ability to prevent engine ice. The average freezing point for a coolant should be -20 degrees Fahrenheit.

Pre-mixed coolant

You’ll come across motorcycle coolants in two distinct forms—pure and mixed.

The mixed one already comes mixed with deionized water, making it different from the pure form which requires you to do the mixing on your own.

So, which one should you get?

In our opinion, getting the pre-mixed is better. This is because it comes ready to use, so you won’t have to go through all the hassle of messing with distilled water as you try to achieve the right proportions and overall solution concentration.

Anti-corrosion properties

Your bike’s engine contains aluminum, brass, alloy, and other metallic parts that can get easily attacked by corrosion and attract costly damages.

To help prevent this, the best motorcycle coolant should contain corrosion and rust inhibitors which help keep corrosion off your engine for an extended lifespan.


We also suggest that you go through the list of ingredients that come with the coolant you wish to buy.

The most common ingredient in motorcycle coolants is ethylene glycol. It’s widely used due to its low freezing point and cheap production cost.

Keep off coolants that contain silicates, phosphates, and other harmful substances. These can not only damage your engine’s magnesium and aluminum components but are also environmentally unfriendly.

If you’re an advocate for nature, consider investing in organic-based products.

Frequently Asked Questions

1. How often should I change my motorcycle coolant?

The coolant life usually varies depending on the type used as well as the operating conditions.

That said, experts recommend that the lifespan of standard motorcycle coolant should be 2 years.

Check your bike’s user manual for more info on the manufacturer’s scheduled maintenance recommendations.

2. What happens if I don’t change my motorbike coolant?

Bad things will happen!

The coolant of your motorcycle usually goes bad after around 2 years. After this, it transits from being helpful to being a villain inside your engine. It becomes more acidic and can start eroding the interior of your radiator, engine, and water pump.

As you can see, not changing your motorcycle coolant after every 2 years, can lead to costly damages, making you spend more than you could have spent on a coolant in the first place.

3. Can I use water instead of coolant on my motorcycle?

Not a good idea! Water alone cannot work on your motorbike’s coolant tank, no matter what the climatic conditions in your area are.

There’s a reason why motorcycle coolant exists. It contains additives that help broaden the water’s freezing and boiling range.

This helps ensure regular water doesn’t freeze and cause serious damage to your motorcycle.

Water alone can even eat away the interior of your bike engine.

The best water-based coolant for your motorcycle should contain the coolant itself and pure (distilled) water mixed in a ratio of 50/50.

4. Does motorcycle coolant go bad?

No. Unlike the coolant being used in your motorcycle radiator, the coolant sitting in a can doesn’t degrade. And this means it shouldn’t expire any time soon.

You just need to follow the manufacturer's recommendations on how to store the coolant to ensure it stays in top shape for years.

Final Verdict

The motorcycle coolant helps keep your motorbike engine running within a safe temperature limit. For this reason, the best motorcycle coolant should come with high boiling and freezing point to be able to do its job perfectly well.

Moreover, the perfect coolant should come with corrosion inhibitors to help ensure the metallic parts of your engine don’t rust or corrode with time.

Our list of the top-rated motorcycle coolants above features best-performing coolants with impressively high boiling/freezing plus added corrosion inhibitors.
