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.
- Since coolant is harmful to the human body, do not use for drinking.
Remove:
- Left Side Cover (see Left side cover removal in the Frame chapter)
- Bolt [A]
- Reserve Tank Cover [B]

Remove the fuel tank (see Fuel tank removal in the Fuel System (DFI) chapter).
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.

Place a container under the coolant drain bolt [A], then remove the drain bolt.
The coolant will drain from the radiator and engine.
Install the reserve tank.

Caution!
- Soft or distilled water must be used with the antifreeze (see Specifications section) in the cooling system.
- If hard water is used in the system, it causes scale accumulation in the water passages, and considerably reduces the efficiency of the cooling system.
Water and coolant mixture ratio (when recommended):
- Soft Water: 50%
- Coolant: 50%
- Freezing Point: -35°C (-31°F)
- Total Amount: 2.2 L (2.3 US gt.)
Tighten:
- Torque - Coolant Drain Bolt: 9.8 N·m (1.0 kgf·m, 87 in4b)
Fill the radiator up to the filler neck [A] with coolant.

Notes:
- Pour in the coolant slowly so that it can expel the air from the engine and radiator.
- Choose a suitable mixture ratio by referring to the coolant manufacturer's directions.
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.
Install the radiator cap.
Fill the reserve tank up to the "F" (full) level line [A] with coolant and install the cap.
Install the fuel tank (see Fuel tank installation in the Fuel System (DFI) chapter).
Start the engine and warm it up thoroughly until the radiator fan turns on and then stop the engine.
Check the coolant level in the reserve tank several times while the engine is cooling down, and replenish as necessary.
★ If the coolant level is lower than the "L" level line [B], add coolant to the "F" level line.

Caution! Do not add more coolant above the "F" level line.
