Best Motorcycle Coolant Buying Guide
These coolants and additives are the best of the bunch, and we’re confident you’ll find the perfect option for your bike somewhere on our list. To help you make an informed decision, we’ve compiled this brief guide. Below, we run through what to look out for in a motorcycle coolant, the different types you can choose from, and how you can maintain it.
What to Look for in The Best Coolant for Motorcycles
When it’s time to choose a coolant for your motorcycle, keep your eyes open for the following:
- Ready Mixed
Although it’s not essential to purchase ready mixed coolant, it can certainly make your life a lot easier. If you’re buying a water-based coolant, ready mixed options are generally best because they tend to use non-ionized water. Unlike the tap water you’d have at home, this water is free from the minerals that can cause corrosion and limescale in the cooling system.
- Long Service Life
We all want to get our money’s worth when it comes to maintaining our bikes – one simple way to do this is by selecting a coolant that’s designed to last. Not only will choosing a quality coolant save you money on top-ups, it can also improve the vehicle’s fuel efficiency, and prevent an array of mechanical issues.
- High Boiling Point
Coolants with a high boiling point do a much better job of channeling heat away from the engine. For this reason, it’s important to look out for a formula with a high boiling point – at least 250 degrees Fahrenheit.
- Antifreeze Protection
Most modern coolants are designed to protect your engine whatever the weather. They achieve this through the inclusion of antifreeze ingredients. Look out of a coolant that can protect your engine at cool temperatures, ideally around -24 degrees Fahrenheit or colder.
- Corrosion Resistance
Without anti-corrosion additives, coolants can slowly cause deterioration inside the cooling system. To help prevent this, look out for a coolant that’s formulated to reduce corrosion. Silicates, phosphates, borates, and more recently carboxylates, are typical corrosion inhibitors to keep your eyes open for.
Different Motorcycle Coolant Types
You may have noticed from our list that motorcycle coolants come in two main categories:
As the name suggests, water based coolants contain water – about 50% of their total volume comprises water, in fact. Some water based coolants can be purchased ready mixed, while others may require you to add water yourself. Water based coolants are the most common type, and tend to be a lot more cost-effective than their waterless counterparts. They’re also more commonly used. However, these coolants tend to have a lower boiling point, and may not be suitable for extreme applications, such as the race track. Water can also be corrosive to the cooling system is it contains certain minerals.
- Water Free
This type of coolant does not contain water. Although it’s more expensive to purchase, this composition virtually eliminates the issue of corrosion in your car’s cooling system. The chemicals used in these coolants also have a higher heat capacity and boiling point than water, allowing heat to be channeled away from the engine more efficiently. This greater effectiveness makes waterless coolants ideal for the harsh conditions of the race or rally track. Water free coolants also tend to last for longer than water based solutions.
Average Operating Temperatures
Average engine temperatures will vary from vehicle to vehicle. In a typical modern car, this temperature should be in the range of 194 degrees Fahrenheit.
Some diesel powered vehicles will run safely at higher temperatures from 210 – 220 degrees Fahrenheit.
Whatever your vehicle’s optimum operating temperature, a high quality coolant will help to maintain it, improving power and efficiency.
Best Motorcycle Coolant FAQ:
Q: What is a motorcycle coolant?
Motorcycle coolant is a liquid used to keep the engine of your vehicle at a safe temperature. When engines burn fuel, energy is released, but only about a third of this energy actually moves the vehicle forward – the rest is lost as heat. For this reason, it’s easy for the engine block to overheat without a cooling system in place. In this system, engine coolant is circulated from the engine block to a radiator on the outside of the vehicle. The coolant absorbs heat from the engine, and becomes cooled as the vehicle moves, before being pumped back to the engine once again. Most coolants are water based, since water has a relatively high heat capacity. The coolant will also contain antifreeze and anti-corrosion agents, to help prevent it from freezing in the winter, or damaging the radiator and other cooling system components.
Q: How often should I change my coolant?
Engine coolant deteriorates over time, through chemical processes such as aluminum corrosion, and acidification. These changes make the liquid less effective at carrying heat away from the engine, and could cause damage to the cooling system. For this reason, it’s important to have your coolant changed every two years, even if you haven’t covered many miles.
Q: How do I dispose of old radiator fluid?
Many types of coolant contain highly toxic ingredients. For example, ethylene glycol is highly poisonous to humans. For this reason, it’s vital that you dispose of old coolant responsibly:
– Ensure the engine is cool
– Drain the fluid by unscrewing the sealing screw beneath the engine coolant tank
– Direct the old fluid into a large plastic bottle or bucket using tubing and a funnel
– When all the fluid has been expelled, remove the tubing and seal the bottle
– Sterilize the funnel and tubing you used thoroughly
– Never pour the old fluid down a drain, skin or toilet
– Label the bottle with its contents (ie. ‘Used coolant’) and mark it as ‘dangerous’
– Contact your local government office, or a knowledgeable garage to find a safe disposal or recycling facility
