WARNING
Antifreeze coolant is flammable, so keep it away from flame.
Antifreeze coolant is toxic. When removing the drain plug, be careful not to get water containing antifreeze coolant on you. If it
gets in your eyes, flush your eyes with large amount of fresh water and see a doctor at once.
Use antifreeze and appropriate water for diluting (for details, see "COOLANT AND WATER FOR DILUTION (PAGE
4-6)")
We recommend use of an antifreeze density gauge to control the mixing proportions.
Prepare a container whose capacity is larger than the specified coolant volume to catch drained coolant.
Prepare a hose to supply antifreeze coolant and water.
1. Stop the engine, then set corrosion resistor valve (1) to the
CLOSE position.
2. Loosen radiator cap (2) slightly to release the air, then remove
the cap.
