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 repairing the 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. (For dilution
water, see “COOLANT AND WATER FOR DILUTION (4-6)”.)
Check the density with a coolant tester.
Items to be prepared
• A container whose capacity is enough to receive the specified capacity of coolant
• A hose to add coolant
1.
Place the machine on a level ground, then stop the engine.
2.
Remove radiator top cover.
3.
Check that the coolant temperature is low enough to make
it possible to touch the radiator cap surface by bare hand,
turn radiator cap (1) slowly until it hits the stopper, and re-
lease the pressure.
4.
Then, while pushing radiator cap (1), turn it until it touches
the stopper, and remove it.
5.
Prepare a container to catch the coolant.
6.
Open drain valve (2) on the left side of the fuel tank, and
drain the coolant.
7.
Tighten drain valve (2) and add tap water.
Add water until it fills the radiator.
8.
Start the engine.
