8. Stop the engine, let the coolant
temperature lower, then loosen the drain
plug (4) and drain the coolant.
9. After draining the coolant, clean using
cleaning agent. Follow the instructions
included with the cleaning agent you are
using.
10. Repeat steps 4 to 8 to flush the cooling
system.
11. Tighten the drain plug (4), then install the
under cover (5).
12. Slowly add the new coolant (mixture of
antifreeze and tap water) through the
radiator’s filler neck up to the top of the
filler neck. Take your time doing this.
13. Close the radiator cap (3).
14. Warm up the engine. Use the instruments
to check that there are no irregularities in
the cooling system at this time.
15. Raise the coolant temperature to at least
90°C (195°F), then run the engine for
about 10 minutes.
16. Stop the engine, let the coolant
temperature lower, then check the level
of coolant in the radiator, and replenish it
up to the top of the filler neck.
17. Close the radiator cap (3).
18. Clean the interior of the reserve tank (1),
then add coolant to the upper limit (H).
19. After replacing the coolant, inspect the
coolant level once again after operating
the machine.
The coolant permeates the entire system
during operation, so the level decreases.
Replenish by the amount the level has
decreased.
