This Year’s Buying Guide

 

When you’re looking for the best motorcycle antifreeze, you need to think about which features would make a product worthy of your attention. We’ve put together some advice in a comprehensive buying guide, and we deliver what we believe to be the easiest way of finding a proper motorcycle coolant.

If you’re currently in the market for items for motorbikers, you should check out our related articles on good Harley Davidson hoodies to buy or getting reliable motorcycle helmet locks.

Compatibility

The first step in choosing the right product for your needs would be to check the user manual for your motorcycle, which should at least outline a recommendation for the type of coolant that should be used with its engine.

Finding the right coolant for your specific model of motorcycle will help extend the life expectancy of particular components, given that they need to be protected against corrosion.

What’s also worth considering is that you need to check the dimension of the tank before you make a purchase and be sure to pick the right amount of liquid to fit its proportions. The process won’t work unless you get the correct amount.

 

Premixed or not

The items available for sale generally come in two forms: premixed or pure. The difference would be that the latter alternative needs to be combined with distilled water before being used, and you need to do that yourself.

It would be a lot easier to get a premixed alternative, given that it can be used straight out of its recipient without any knowledge about which are the right amounts to mix to obtain a proper concentration.

You can make this decision according to your budget, or you can consider your skill in mixing ingredients or patience to read instructions. Just make sure that you don’t ruin your engine with a liquid that’s not prepared correctly.

A high concentration can result in damage to the metallic components, due to the buildup of hard water deposits. In time, this can affect the process and make your vehicle impossible to use.

Ingredients

It’s important when choosing a motorcycle coolant for hot weather to consider issues like environmental protection or user safety. This kind of products can contain harmful substances, and you need to carefully check the description file from the manufacturer to make sure your health won’t be in danger.

Avoid anything that contains phosphates, silicates or other harmful substances. Not only do these damage the aluminum and magnesium parts by causing corrosion, but they’re also not environmentally friendly.

Search for organic-based items if you are concerned about nature and if you do not require and anti-corrosive coolant.

Switching from one coolant to another

It can be challenging to change the coolant liquid that you use, and it needs some work beforehand. If you’re switching from a silicate-based formula to an organic one especially, the process can be awkward.

The first thing you need to do is to make sure that the system is thoroughly flushed and any traces of the old coolant are removed. That is, of course, unless you manage to find an alternative which is compatible with other types of coolants, which would cut a lot of corners.

Factors such as price and availability might influence your chances to find such an option, but if you’re looking for a fast way to make a much-needed change, then it’s worth looking into this issue.

 

Protection

It’s essential to look for the product that can offer your engine the necessary protection no matter the weather conditions. If it’s during the summer, then make sure that it can keep your operating temperature within safe limits, as per required by your vehicle.

When it comes to wintertime riding, you need to check the freezing temperature of the coolant and decide whether it’s compatible with your needs and the climate you’re going to ride your bike in.

Other aspects such as protection against corrosion have been covered before, but it’s worth mentioning that you need to keep an eye out for an item that can meet as many of your requirements as possible.

 

Motorcycle coolant types

As we’ve said before, the market offers coolants that come premixed or not. Choosing between these two types is just a matter of preference, after all. If you don’t find it difficult to add water to a coolant, then you can opt for a formula that does not come premixed as it might be a bit cheaper. 

Coolants can be further divided into two other categories: water-based and water-free coolants. The water-based coolants are the ones we’ve mentioned above and they come premixed or not. This type is the most common among motorcycle riders. One reason behind that is that they are more cost-effective. 

The downside with these coolants is that they might not be ideal for certain applications such as racing since they have a lower boiling point. Moreover, if you want to use a water-based coolant, read the ingredient list to see if it contains any anti-corrosion ingredient. Otherwise, various parts of your cooling system and even the engine might get damaged, which will send you to a service for bikes sooner than expected. 

You will also find water-free coolants. One of the main advantages of these products is that, since they contain no water, they eliminate the risk of corrosion. Plus, they contain ingredients that have a higher boiling point and heat capacity than water-based coolants. 

This means that they will keep heat away from the engine more effectively and are thus suitable for more extreme applications such as racing. What’s more, this type of coolant usually lasts for longer than the one based on water. The drawback is that they are also more expensive. 

It is always a good idea to read a few reviews before purchasing a certain product to see how it helped other bike owners and users. 

Coolant brand 

With so many coolants out there, choosing the right one might prove to be a challenging task. Once you have identified the specific needs of your bike, you can further ease your shopping process by considering the brand of the coolant you need. Going for a reputable brand makes it more likely for you to get a quality product that will do its job as advertised. 

There are indeed emerging brands that offer noteworthy solutions and if you want to try one of them, it is best to read a few reviews before your purchase. However, some of the most appreciated engine coolant manufacturers include, but are not limited to, Engine Ice, Maxima, Honda, Motorex, Motul, Evans, and Royal Purple, just to name a few. 

The fame and appreciation of a brand are usually built thanks to the quality of the products offered. If this is not the first engine coolant you buy and you don’t want to risk trying something newer, then sticking to the brand that covered your needs successfully is the thing to do. 

 

Boiling point and durability

Bikes are employed for different applications. You can use yours just to get from one place to another or to engage in more extreme activities such as racing. The coolant you use should be formulated to keep up with your specific needs; therefore, another key factor to consider is the boiling point of the product you’ve set your eyes on. 

If races are part of your regular activities, you might want to choose a coolant that has a high boiling point starting at 250 degrees Fahrenheit. Coolants should protect your motorcycle no matter the weather, cold included. Opt for a product that contains antifreeze ingredients. A coolant lacking antifreeze will not protect your engine when the temperature goes down. 

The ingredient list is again the one to check before you add anything to your shopping cart. If you see no antifreeze ingredient and you intend to use your bike even when it gets cold, keep searching for a coolant that has antifreeze properties as well. 

A quality coolant does not only last but it can also improve your bike’s fuel efficiency, which can further prevent some mechanical issues. This translates into fewer visits to the motorcycle service. As we always say, reading a few reviews before buying a certain product can also help you get an idea of what it can provide you with. 

Frequently Asked Questions

 

Q: What are motorcycle coolants?

Bike engines can get really hot when working, given their mechanism. Without the use of engine coolant, the engines would reach high unsafe temperatures; therefore, a motorcycle coolant is a cooling liquid that will help your bike engine temperature stay at a safe level. 

In order to make the vehicle move, the engine burns fuel and thus energy is released. The thing is that only a third of this energy makes the motorcycle move. The remaining energy will be lost as heat. Without a cooling system, the engine block can easily overheat. 

Such a system is designed to circulate the engine coolant from the engine block of the bike to the radiator placed on the exterior part of the motorcycle. The heat from the engine is then absorbed and this system will keep the engine cool throughout your ride.   

Most engine coolants are based on water because of the high heat capacity water has, but they are also formulated with anti-corrosion agents and antifreeze. Such ingredients are added to the coolant to make sure no parts of the cooling system get damaged in the process and to prevent it from freezing when the temperatures get really low. 

 

 

Q: What kind of coolant do motorcycles use?

To make sure that you don’t damage your motorcycle engine and you get to benefit from a long-lasting cooling performance, it is best to use an engine coolant that was specifically formulated for bikes. When prospecting the market for a quality coolant for your ride, you will see that there are two types of such products. 

Propylene glycol coolants are considered to be the safest choice for motorcycles. You will also find ethylene glycol coolants, yet they are considered to be poisonous to humans. Regardless of the one you want to use for your bike, you should always make sure that you don’t mix the two types. 

Thankfully, the two coolant types have different colors to make it easier for you to identify the one that’s in your system. Before buying an engine coolant for your bike, make sure you read the ingredient list and avoid the ones that contain phosphates or silicates. 

Such ingredients will cover the metals of the cooling system with an insulating layer. If this layer gets too thick, the heat that should be transferred from the engine into the coolant might be reduced and, therefore, the engine might overheat. Moreover, such ingredients can affect the water pump seals. 

 

Q: Can you use regular coolant on a motorcycle?

If by regular coolant you mean car coolant that contains ethylene glycol antifreeze, yes, you can use it on a motorcycle. Many car and motorcycle engine coolants contain the same ingredients and, therefore, can be used for both types of vehicles. However, you must check its list of ingredients carefully before doing that. 

To make sure that heat is not a problem and the bike engine stays at a safe temperature for a longer time, it is best to go for the products that are designed for bikes as they will provide you with longer cooling performance.

There are various reasons why the market now offers different engine coolant categories and that’s because they were specifically formulated to meet certain needs. For example, motorcycle radiators feature aluminum parts and the coolant you choose should thus be safe to use with such materials. 

What’s more, it is best to mix it with ionized water to prevent scale from building up. If you use impure water, it is more likely for scale to form, which will cause further problems. Some motorcycle coolants come premixed with distilled water, another reason why it best to use a bike coolant if you can. Before purchasing it, read the ingredient list carefully and avoid products that contain phosphates or silicates. 

Q: How do you flush the coolant on a motorcycle?

Flushing the coolant on your bike holds great importance if you want your vehicle to work properly and the engine coolant to do its job. If you don’t have any previous experience yet you don’t want to go to a bike service for professional help, you can take care of that yourself as long as you follow a few simple steps. 

First of all, make sure that the engine is cool before getting started, then identify the coolant drain bolt. Bikes are different and, in some cases, this part might not be easy to spot. Continue by removing the radiator cap. 

Place a drain pan under the drain bolt and back the bolt out to allow the engine coolant to drain. As soon as the coolant stream is reduced to a light drip, you should tighten the bolt back up. Now, pour distilled water into the cooling system using the cap opening placed at the top of the radiator. 

Drain the water just as you did with the coolant. Plus, make sure you drain any old coolant that might be left in the reservoir. Add the new coolant to the system, place the radiator cap back, and reinstall any other parts that have been removed. Once everything is in place, you can start the engine and check if there are any leaks.
