This is my 2nd coolant change for the bike and I thought I will document the procedures here with pictures. Caution: Do it when the Radiator is cool at room temperature.
Here are the Tools and Fluids I am using:
1. Toyota Long Life Coolant, 1L - safe for all Japanese vehicles (something about no phosphates and silicates that can destroy seals in the water pumps)
2. Motul MoCool - 5% per total radiator volume. Improves heat removal.
3. Measuring cup: Since I live in the tropics, freezing is something I don't get so I am going with a 30% Coolant, 5% MoCool and 65% Water (filtered soft). The higher the water content, the better the cooling efficiency it gets.
4. Total volume of radiator, expansion tank, all routes: 1.9L
Start off with removing these 3 screws.
Now you can access the Radiator Cap.
Open up the Drain plug with a 8mm Socket Hex tool bit. Collect the coolant with a bucket.
Inspect the cap for rust or damage or build up. This one looks healthy so there is no need for a Radiator cleaning service.
Place a funnel on the intake and flush the radiator with water (tap water in my country is soft. If the water source is hard which contains minerals, then it is better to flush it with RO, DeIonized Water, battery water etc. Minerals in hot water = precipitation forming on hot metal surfaces. Flushed as many times until the exit water is clear. I did about 3 liters of water to clear it.
Now, onto the Expansion tank. I use a pump from a Body Gel bottle. Pumped out as much as possible. May add in fresh water and pump out a 2nd time.
Close up the drain plug.
Fill in the Mixture of Coolant/Water via this funnel. It takes about 1.7L to fill the radiator to the brim. The other 200ml would be to the Expansion tank.
Remove the funnel to expose the intake. Carefully pour into the intake, slowly so that it doesn't spill out but allows the excess to flow into the Expansion tank via a small black rubber hose connected at the intake. Fill in until the Expansion tank is full.
Fill until the expansion tank is full. Closed up the Radiator Cap fully. Warm up the bike and check for leaks and add in if insufficient as indicated by the expansion tank levels.
