Warning: To avoid burns, do not remove the radiator cap or try to change the coolant when the engine is still hot. Wait until it cools down. Coolant on tires will make them slippery and can cause an accident and injury. Immediately wipe up or wash away any coolant that spills on the frame, engine, or other painted parts. Since coolant is harmful to the human body, do not use for drinking.

- Remove the radiator cap [A] in two steps. First turn the cap counterclockwise to the first stop. Then push and turn it further in the same direction and remove the cap.
The coolant will drain from the radiator and engine.

- Remove the reserve tank [A] from the frame bracket [B].
- Remove the reserve tank cap, and pour the coolant into a suitable container.
- Place the reserve tank on the right side of frame.
- Tighten the drain bolt with the gasket.

Replace the drain bolt gasket with a new one.
Torque-Water Pump Drain Bolt: 9.8 Nm (1.0 kg·fm, 87 in·lb)
- When filling the coolant, choose a suitable mixture ratio by referring to the coolant manufacturer's directions.
Caution: Soft or distilled water must be used with the antifreeze in the cooling system. If hard water is used in the system, it causes scales accumulation in the water passages, and considerably reduces the efficiency of the cooling system.
Water and Coolant Mixture Ratio (Recommended)
- Soft Water: 50%
- Coolant: 50%
- Freezing Point: -35°C (-31°F)
- Total Amount: 1.2 L (1.3 US qt)
- Fill the radiator up to the filler neck [A] with coolant.

Note: Pour in the coolant slowly so that it can expel the air from the engine and radiator.
- Check the cooling system for leaks.
- Tap the radiator hoses to force any air bubbles caught inside.
- Fill the radiator up to the filler neck with coolant, and install the radiator cap.
- Install the reserve tank bracket and reserve tank.
Put the projection [A] on the reserve tank bracket into the hole [B] on the frame bracket.

- Fill the reserve tank up to the "F" (full) level line [A] with coolant and install the cap [B].
- Start the engine, warm it up thoroughly until the radiator fan turns on and then stop the engine.
- Check the coolant level in the reserve tank after the engine cools down.
If the coolant level is lower than the "L" level line, add coolant to the "F" level line.

Caution: Do not add more coolant above the "F" level line.
Radiator Hose and O-ring Replacement
- Drain the coolant (See Coolant Change).
Remove:
- Thermostat Housing [A] (See Water Pump Removal in the Cooling System chapter)
- Water Pump Cover [B] (See Water Pump Removal in the Cooling System chapter)
- Hoses [C]
- O-rings [D]
- Apply grease to the new O-rings and install them.
- Install the new hoses and tighten the clamps securely.
- Fill the coolant (See Coolant Change).
- Check the cooling system for leaks.
