WARNING
• Coolant is toxic. When opening the drain valve, be careful not to get coolant on you. If it gets in
your eyes, flush your eyes with large amount of fresh water and see a doctor immediately.
• When handling the cooling water containing coolant that has been drained during changing the
coolant or repair of radiator, contact your Komatsu distributor or request a qualified company to
perform the operation. Coolant is toxic, so never pour it into drainage ditches or drain it onto the
ground surface.
Non-Amine Engine Coolant (AF-NAC) is already diluted with distilled water, so it is not flammable.
Check the density with a coolant tester.
Prepare a container whose capacity is larger than the specified coolant volume to catch drained coolant.
Prepare a hose to use when filling with coolant and water.
1.
Stop the engine.

it possible to touch the radiator cap surface by bare hand,
turn radiator cap (5) slowly until it hits the stopper, and re-
lease the pressure.
6.
Then, while pushing radiator cap (5), turn it until it touches
the stopper, and remove it.
