24.9.1 DRAIN, FLUSH AND REFILL COOLING SYSTEM

Soon after the engine has been stopped, the coolant is hot and can cause personal injury. Allow the engine cool before draining the coolant.

Never remove the radiator cap when the engine is at operating temperature. At operating temperature, the coolant is under pressure. Steam blowing up from the radiator could cause personal injury.

Allow the engine to cool until the radiator filler cap is cool enough to touch with your hands. Remove the filler cap slowly to relieve pressure.

Never be under the machine with the engine running. To avoid serious injury, always stop the engine before being under the machine to open the drain valve.

When removing drain plug, avoid pouring coolant on yourself. + Antifreeze is flammable, so keep it away from any flame.

Flushing agents, neutralizing agents, and anticorrosive agents are strong acids or alkalize, so be careful not to get them on your skin.

If you should get any of these on your skin, wash off immediatelywith ample water.
