At operating temperature, the engine coolant is hot and under pressure.

Steam can cause personal injury.

Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand.

Remove the fill cap slowly to relieve pressure.

Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.

1. Drain the engine coolant into a suitable container for storage or for disposal. Drain the coolant to a level that is below the water temperature regulator. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct procedure.
