– [MATT] Hey, what's that for everyone, it's Matt from HowToMotorcycleRepair.com. In this video I will show you how to replace the coolant on your motorcycle.
Now there are a few reasons why you sometimes need to replace the coolant. Like any other fluid, it will break down over time and not perform its job. Coolant, also called frost protection, helps regulate engine temperature and prevents the system from freezing or overheating.
As refrigerant times, its freezing point rises normally. While coolant lubricates the water pump seals, so sticking to coolant changes can help prolong the life of these components. And finally, the coolant has anti-corrosion additives to protect the engine and the radiator. So for these reasons, most manufacturers recommend replacing refrigerant every two years.
Before you start working, make sure you have the right safety equipment: goggles and gloves. Also make sure the motorcycle is at room temperature. Do not perform this job when the engine is hot. The cooling system is under pressure and is not safe to open when hot. Okay, let's talk about some of the tools you need for the job: a sewer, some hand tools, some rags, new coolant
Having the service manual at hand is also a really good idea. It will have information such as how much coolant is needed, and also where the drainage and filling point is. I would also like to mention that it is very important to use the type of coolant specified in the service manual. You may be tempted to use car coolers, but most are not rated for use in motorcycles. Your best bet is to buy coolant from your nearest motorcycle dealer. Most coolants are premixed with water and are ready to pour directly out of the bottle.
The first step in changing the coolant is to locate the drain screw located at the lowest point in the cooling system. On some motorcycles like this model, the brackets must be removed to gain access to the radiator cap and coolant drain plug. The window is usually easily removed by removing some screws.
When the drain pipe is in place, remove the screw and allow the coolant to drain into the boiler. At this time, you can loosen and slowly remove the cooling bottle to accelerate emptying.

Depending on the model, there may be a copper noise tray on the drain bolt that helps prevent leaks. If so, it is a good idea to install a new crushing tray for proper sealing. Once all coolant has been dropped, you can reinstall the bypass screw. Then find the overflow container, which is usually near the seat or behind a brass, and drain or extract the liquid with a turkey bark or liquid extractor.
Transfer the old coolant to a sealable container. Empty milk gallon containers work well for this. Keep the liquid out of the reach of children and pets until you can take it to a local car dealership that recovers coolant.
Then use a funnel and slowly pour new liquid into the cooler. Continue filling until the liquid level is half an inch or so from the top. Reinstall the cooling cap. Do not forget to fill the overfill container with coolant.

Now you can start the motorcycle and let it go up to full operating temperature. While heating up, check the drain screw for any signs of coolant leakage. When fully heated, turn off the motorcycle and allow it to cool to room temperature.
Remove the cooling cap again and see if the fluid needs to be refilled. In most cases, the level will be slightly lower due to air bubbles released during heating.
Finally, install the windows to finish the job.
Okay, I hope you enjoyed this video about changing the coolant on your motorcycle.
