At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Drain the coolant only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap from the radiator slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
1. Drain the coolant from the radiator. The capacity of the cooling system is 30 liters (7.8 U.S. Gal).
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause severe burns. Remove the drain plug only when the engine is stopped, and the drain plug is cool enough to touch with your bare hand.
2. Drain the hydraulic oil tank. The capacity of the hydraulic oil tank is 125 liters (32.5 U.S. Gal).3. Remove the hood assembly.
