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 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.
2. Release the pressure in the cooling system by slowly loosening the filler cap on the radiator. Drain the coolant from the radiator into a suitable container for storage or disposal. The capacity of the cooling system is 49 liters (12.7 U.S. gal).3. Remove the engine compartment doors. Remove the crankcase guard from under the engine.
